Abstract

To Select an appropriate medium for the growth of plant is one of the problems of most greenhouse owners in production of pot ornamentals. So, current research was conducted to evaluate effect of some available media in mixtured by perlite on the growth of pothos. Study was based on a completely randomized design with 5 treatments, 8 measuring times and 6 replications in a fiberglass greenhouse of Gorgan University of Agricultural Sciences and Natural Resources during 2009-2010. The treatments include ratios of perlite+ leaf compost, perlite+ rice husk, perlite+ cocopeat, perlite+ composted forest trees and perlite+ mushroom compost. Parameters such as plant height, stem diameter, leaf number, leaf fresh and dry weight and chlorophyll content were measured. Moreover, plants were compared according to their overall shape and appearance. The results of data analysis showed that the effect of medium, measuring time and their interaction were significant in all
traits. The marketing value of pothos including plant height, leaf number and chlorophyll content, had a better response in perlite+ leaf compost and perlite+ mushroom compost media.
