ثیرا توماوونگسا چاتاپوند موزیموندو سانتی واتانا استفان گیل راتاکت چویکلین نطاووت ویریاتاناودی وونگ نودوان موانگسانشماره 1 , دوره 14 , بهار 2024Habenaria janellehayneana Choltco, Moloney, & Yong Gee (Orchidaceae) is a lithophytic orchid with striking pink flowers that is endemic to Phitsanulok Province, northern Thailand. Only a few populations of this species are found in Phu Hin Rong Kla National Park. To چکیده کاملHabenaria janellehayneana Choltco, Moloney, & Yong Gee (Orchidaceae) is a lithophytic orchid with striking pink flowers that is endemic to Phitsanulok Province, northern Thailand. Only a few populations of this species are found in Phu Hin Rong Kla National Park. To maintain rare plant species in ex situ collections thereby preventing extinctions, along with the aim of mass propagation for ornamental reasons, it is crucial that suitable propagation methods are developed. In this paper, we describe protocols for the asymbiotic and symbiotic germination of H. janellehayneiana. Of the four growing media tested, germination percentages were greatest on ½ VW (18.97%), followed by ½ MS (14.20%), MS (12.46%), and VW (11.93%) at 16 weeks, and protocorm development was most advanced (stage 4) within 10 weeks. Of the three plant growth regulators tested, including 6-benzylaminopurine (BAP), gibberellic acid (GA), and thidiazuron (TDZ), at 0, 1, 3, and 5 mg/L concentrations, 1 mg/L BAP significantly enhanced seed germination (p <0.05) when compared to the control (8.47%). For symbiotic seed germination, two non-mycorrhizal endophytic fungi isolates of the genera Aspergillus and Colletotrichum increased seed germination by 14.03% and 11.00% respectively, when compared to the control (6.15%). These findings demonstrate that it is possible to germinate the seeds of H. janellehayneana via both asymbiotic and symbiotic method, with a symbiotic approach providing the best outcomes, and this could assist in the conservation of this and other rare terrestrial orchids, as well as increase their value in the ornamental market. پرونده مقاله -

2 - Wastewater Treatment through Ornamental Plants: A Review
Zia Rehmanشماره 1 , دوره 11 , بهار 2021This review deals with two untreated wastewater types, including domestic wastewater (in tourist destinations) and pharmaceutical industry wastewater, to shed light on the efficiency of constructed wetlands (CW). In mountainous areas, it has always been difficult to hav چکیده کاملThis review deals with two untreated wastewater types, including domestic wastewater (in tourist destinations) and pharmaceutical industry wastewater, to shed light on the efficiency of constructed wetlands (CW). In mountainous areas, it has always been difficult to have a proper sewage treatment and disposal system for which a proper method is proposed in this paper. In CW, toxic materials should be removed from the water for which a surface CW layer is constructed. Ornamental plants (Canna flaccida, Zantedeschia aethiopica,and Canna indica)were used inthis study and they showed usefulness in reducing 80% of BOD (biological oxygen demand) and COD (chemical oxygen demand). Carbamazepine is a pharmaceutical drug that is widely used and pollutes aquatic environments when it is discharged untreated. This problem can be solved by constructing a horizontal subsurface flow wetland in which the vertical subsurface flow in the wetland is considered and the wastewater is then stabilized in ponds. Three different ornamental species were used (Thypha latifolia, Iris sibirica,and Zantedeschia aethiopica) and their performance was explored on parameters like dissolved oxygen, pH, oxidation/redox potential (Eh) whose average mass removal was 62.5 ± 4.5% and 59.0 ± 4.5%, respectively. The results showed the amazing performance of the two former species. The ornamentals used to get the flowers for commercial production included Zantedeschia aethiopica, Strelitzia reginae, Anthurium andraeanum and Agapanthus africanus. After the system was supplied with the target wastewater, Zantedeschia aethiopica grew about 60 flowers and maintained a healthy outlook while other species grew large leaves, and some died due to the harsh environmental conditions. The reviewed data depicts that Canna indica gave great results for the BOD and COD removal with Z. aethiopica having the potential of giving a greater number of flowers while tolerating the weather conditions. However, for carbamazepine, two species that could take up the pollutants were found to be Iris sibirica and Zantedeschia aethiopica. پرونده مقاله -

The findings presented here are the results of the study of several hundred papers published all over the world. Tissue culture techniques are routinely used for micropropagation. Enhancement of efficiency and efficacy of plant regeneration are primary goals of micropropagation. In this article, maximum and minimum use of some basic issues concerned with plant tissue culture in vitro especially micropropagation such as types of explants, types of culture media, types of sterilizing agent for explants, types of plant growth regulators (PGRs) for general studies of miro-propagation, shoot and root induction, somatic embryogenesis (SE) and callus induction have been considered. Maximal application for explants, culture media and sterilizing agent are single node, Murashige and Skoog (MS) and sodium hypochlorite (NAClO), respectively. BA and NAA are the most application among cytokinins (CKs) and auxins for general studies of miroprop-agation. Among all PGRs used for general studies of miropropagation, NAA is on the top. BA and IBA are the most use among CKs and auxins for shooting and rooting of explants, respectively. 2,4-D, NAA and TDZ are used more than the other PGRs for induction of SE. Among all types of auxins and CKs used as singular or in combination with them for callus induction, 2,4-D is at the top level. Combination of BA and NAA is the maximum for general studies of miropropagation. This review article can help to the future studies on micro-propagation due to the correct selection of the treatments پرونده مقاله -

We report the result of three replications and a factorial design experiment that assesses the effect of plants (Epipremnum aureum and Dracaena trifasciata ) on the removal of indoor air pollution. To gain the objects, potted plants were placed individually in 125 liters airtight glass containers (chamber) which had a small valve to inject and sucking airs. Each plant was exposure to, benzene 25 and 50 µl/l, acetone 25 and 50 µl/l, ethanol 50 µl/l and methanol 50 µl/l during a day (24 hours). According to the biochemical examination electrolyte leakage (%) of pothos was decreased especially in acetone 25 µl/l versus on treated sansevieria increased. Total chlorophyll content of sansevieria in all treatments was increased, while it was decreased when pothos exposure to benzene 25, benzene 50 µl/l and methanol 50 µl/l catalase activity and superoxide dismutase showed converse results. In both plant species catalase activity was decreased especially in acetone 50, however superoxide dismutase activity was increased in all treatments and in sansevieria exposure to benzene 50 µl/l more than others. There was no significant change in proline content of pothos, although there was significant increase in acetone 50 µl/l and ethanol 50 µl/l of sansevieria. The results indicate when plants exposure to the benzene, tissue cells damaged more than other treatments while, acetone had least amount of tissue cell damage. According to this paper results, both plant species have the potential of indoor air pollution phytoremediation but, pothos had higher adaptability in pollutant indoor area. پرونده مقاله -

Proline is one of the active amino acids in the osmotic regulation phenomenon and it has an effective role in reducing cell damage and improving drought tolerance. A pot experiment as factorial arrangement in a completely randomized design with three replications was performed in order to study the effect of foliar application of proline (0, 50 and 100mg L-1) on some morpho- physiological characteristics of pot marigold under drought stress (normal irrigation, 25, 50 and 75 % field capacity). The results showed that the highest fresh and dry weight of aerial organ, longevity of the flower on the plant, carotenoid and total chlorophyll were observed in normal irrigation+ proline 100 mg L-1. The highest fresh and dry root weight, root length and total antioxidant activity (DPPH) were for 75 % FC + proline 100 mg L-1. The highest plant height and number of flowers were in normal irrigation+ proline 50 mg L-1. The highest proline content was belonged to 25 % FC+ proline 100 mg L-1. In general, the results of this experiment showed that application of proline can partially compensate for the adverse effects of dehydration and on the other hand, despite the fact that the pot marigold plant is always able to survive in drought stress, it is recommended to irrigate 75% FC in order to increase pot marigold performance. پرونده مقاله -

The aim of this study was to determine histological events during graft union formation in Gymnocalycium cactus influenced by BA (Benzyladenine) application, grafting method and rootstock. The basal end of the scions and the top end of the rootstocks were first dipped into BA solution at concentrations of 0, 100 and 500 mg L-1 for 10 s, before being grafted on Lemaireocereus marginatus and Myrtillocactus geometrizans rootstocks using horizontal or wedge techniques. Longitudinal sections of the graft union were taken weekly to observe the developmental process of graft formation. The rootstocks did not have a significant effect on grafting success and scion growth, while horizontally grafted Gymnocalycium showed better grafting success rate. The grafting rate and scion growth were enhanced by application of BA compared with the control. The best results were obtained from treating the graft cut-surfaces of both scions and rootstocks with 100 mg L-1 BA. Histological observations showed that the graft union process involved development of a thin necrotic layer, callus formation at the graft interface, cambium differentiation and initiation of new vascular elements, developing the new vascular tissue, and connection of scion and rootstock vascular bundles. BA stimulated rapid proliferation of callus between the scion and rootstock as well as differentiation of vascular elements. We suggest the horizontal graft and application of BA (100 mg L-1) on the cut surfaces of both scion and rootstock as an easy and reliable method for successful graft union in Gymnocalycium cactus, which may have potential use in the commercial production of other cactus species as well. پرونده مقاله -

Balanced and optimal nutrition is easily چکیده کاملLilium is scientifically named Lilium longiflorum is a cut bulbous flower. In the process of producing lilium flowers, the quality of the flowers has a special importance and one of the most important factors is proper nutrition. Balanced and optimal nutrition is easily possible in hydroponic systems. In contrast, improper management of the nutrient solution significantly reduces plant growth and impairs the quantitative and qualitative production of the product. Nutrients often interact and the diagnosis of deficiency or toxicity of the nutrients is made by experimental studies under controlled conditions. In order to study the effect of different concentrations of potassium on lily growth and postharvest life, a hydroponic experiment based on a randomized complete design with different concentrations of potassium at three levels of 0, 3 and 6 mM in three replicates in planting bed of 40% perlite + 60% sand was performed. The results showed that most of the plant growth indices, especially shoot dry weight, decreased with potassium consumption in nutrient solution, but at a concentration of 6 mM potassium in nutrient solution, postharvest life increased significantly compared to the control. پرونده مقاله -

The reason is mainly coming from their versatility in handling and mounting, long working time, wattage use efficiency and lower heat production. In this study we examined their potential in promoting seed germination and producing quality flower seedlings for which we designed four growth chambers each equipped with a different light quality sources, namely red, blue, combination of 25% blue and 75% red and fluorescent lamps. Seeds of four annual bedding flowers including impatiens (Impatiens balsamina), zinnia (Zinnia elegans), petunia (Petunia × hybrida) and verbena (Verbena aubletia) were sown and grown to produce seedlings. Plants were illuminated 12 hours per day in the growth chambers. According to the results, seedlings under red light showed the highest emergence percentage, rate and value. Light quality variably affected growth characteristics among plant species. Impatiens and zinnia plants under blue light showed a significant increase in leaf number. The stem diameter of impatiens increased under red light. By contrast, in petunia stem diameter increased under blue light significantly. Inclusion of 25% blue light to red light reduced hypocotyl and shoot height and increased root fresh weight and root length of most plant types. Light quality did not affect the time of emergence (T50), true leaf stage, four-leaf stage and shoot fresh weight. Our study demonstrated that light-emitting diodes could be an effective and reliable source of lighting under controlled environment for production of quality flower seedlings. Generally, the pure red light enhanced seedling emergence and during growth period, high quality seedlings could be produced when 25% blue light was added to red light. پرونده مقاله -

However, there are arguments that some organic types of mulches prevent seed germination and the growth of plants due to their allelopathic effects. This study examined the allelopathic influence of the extracts of some organic mulches on seed germination percentage, and growth of the seedlings of some ornamental plants in two interrelated experiments. In the first experiment, allelopathic effects of six organic mulches including pine wood chips of the plane tree, pine cones, pine leaves, pine barks, sawdust,and grass clippings of Festuca arundincea were examined on germination and early growth of lettuce seeds as an indicator species. The second experiment was designed based on the results of the first experiment so that the extracts of the mulches with the lowest germination rates were selected and their effect on seed germination of five flowering plants of Alyssum maritimum, Celosia argentea, Tagetes sp., Zinnia sp. and Rudbeckia sp. were evaluated. The results showed that pine leave extracts had inhibitory effects on germination of lettuce seeds (in the first experiment) and also showed significant and strong inhibitory effects (P<0.01) on seed germination, radicle length, plumule length, plumule fresh and dry weights of all seasonal flowers. Based on these results, pine leaves after being released in the soil or after decomposition may act as a source of allelochemicals and should be used by care as mulch in landscaping at least if it is combined with ornamental plants. پرونده مقاله -

The aim of the study i چکیده کاملSansevieria zeylanica is a species of xerophytic perennial herbs with a wide range of distribution found in dry tropical and subtropical parts of the world. It is a wonderful medicinal plant and holds the widespread range of beneficial properties. The aim of the study is to determine the cytotoxic activities of the human breast cancer - MDA-MB-231 cell lines and to evaluate the anti-microbial activities by employing the methanolic leaf extracts of S. zeylanica plants. The main experiment was to determine the susceptibility of a microbial organisms against the methanolic leaf extracts of S. zeylanica. The percentage growth inhibition was calculated and concentration of sample to inhibit cell growth by 50 % (IC50) values was generated for the percentage viability. The leaf extracts produced from S. zeylanica plants showed a cytotoxic effect against the human breast cancer - MDA-MB-231 cell lines. The IC50 value of 1167.78 µg/ ml was obtained for the MDA-MB-231 cell lines after the exposure of 24 h treatment. The increase in cell death of MDA-MB-231 cell lines with an increase in the concentration indicates that the methanolic leaf extract of S. zeylanica plants was found active. For the first time, we made an attempt to examine the biological properties of methanolic leaf extracts from S. zeylanica plants with reference to their wide applications. The results obtained support for the therapeutic applications and this acts as an anti-microbial agent. These studies showed the results from the phytochemical screening, anti-microbial and cytotoxic activities of S. zeylanica indicating that this plant as a “natural herbal source”. This can be used for its pharmaceutical and pharmacological applications in a large-scale industry. پرونده مقاله
