comparison of different pot mixtures containing perlite on growth and morphological characteristics of pothos (scindapsus aureum l.)

To select an appropriate medium for the growth of plant is one of theproblems of most greenhouse owners in production of pot ornamentals. so,current research was conducted to evaluate effect of some available media inmixtured by perlite on the growth of pothos. study was based on a completelyrandomized design with 5 treatments, 8 measuring times and 6 replicationsin a fiberglass greenhouse of gorgan university of agricultural sciencesand natural resources during 2009-2010. the treatments include ratios ofperlite+ leaf compost, perlite+ rice husk, perlite+ cocopeat, perlite+ compostedforest trees and perlite+ mushroom compost. parameters such as plant height,stem diameter, leaf number, leaf fresh and dry weight and chlorophyllcontent were measured. moreover, plants were compared according to theiroverall shape and appearance. the results of data analysis showed that theeffect of medium, measuring time and their interaction were significant in alltraits. the marketing value of pothos including plant height, leaf number andchlorophyll content, had a better response in perlite+ leaf compost andperlite+ mushroom compost media.
