1. Evaluation of the Mechanical Strength of Gerbera Flower Stem in Response to Silicon and Salicylic Acid Application

Mesbah Babalar; Behzad Edrisi; Roohangiz Naderi

Volume 6, Issue 3 , Summer 2016, , Pages 163-171

Abstract
  Stem and peduncle bending by the weight of the flower is one of the main postharvest problems in gerbera (Gerbera jamesonii Bolus.) and sometimes caused stem crushing or water loss. In this research, silicon and salicylic acid were applied to enhance the mechanical strength of inflorescence stem, and ...  Read More

2. The Enhancement of Drought Stress Tolerance of Kentucky Bluegrass by Prohexadione-Calcium Treatment

Javad Rezapour Fard; Mohsen Kafi; Roohangiz Naderi

Volume 5, Issue 4 , Autumn 2015, , Pages 197-204

Abstract
  Kentucky bluegrass (Poa pratensis L.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. Oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. The objective of this ...  Read More

3. Exogenous Putrescine Delays Senescence of Lisianthus Cut Flowers

Davoud Ataii; Roohangiz Naderi; Azizollah Khandan-Mirkohi

Volume 5, Issue 3 , Summer 2015, , Pages 167-174

Abstract
  The anti-senescence biogenic polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) are involved in plant growth processes and responses to stress. The physiological mechanism of exogenous Put to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh ...  Read More

4. Delaying of Postharvest Senescence of Lisianthus Cut Flowers by Salicylic Acid Treatment

Davoud Ataii; Roohangiz Naderi; Azizollah Khandan-Mirkohi

Volume 5, Issue 2 , Spring 1394, , Pages 67-74

Abstract
  Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were ...  Read More

5. Pollen Germinability and Cross-Pollination Success in Persian Cyclamen (Cyclamen persicum Mill.)

Mohammad Kermanshahani; Roohangiz Naderi; Reza Fattahi; Ahmad Khalighi

Volume 4, Issue 4 , Summer 1393, , Pages 65-73

Abstract
  Low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. This study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. In order to achieve a high level of pollen germination, the effect of different ...  Read More
