Abstract :
AbstractDetection of medicinal plants growth under different irrigation conditions and drought stress can be a guide to planting resistant plants in arid or low water areas. In order to evaluate the effect of manure and mycorrhizal fungi on physiological indices of growth of naked seed pumpkin seedlings (cucurbita pepo L.) in underwater stress conditions, a split factorial in randomized complete block design with four replications in spring and summer 2009 The research center of Faizabad, Qazvin Agricultural and Natural Resources Research Center, was conducted. Irrigation at three levels including: I1 = 60, I2 = 120 and I3 = 180 (millimeter evaporation from a class A evaporation pan) in the main plots that were applied in the pre-flowering stage and the manure factor was at three levels: 0, 15 and 30 ton/ha, along with mycorrhizal fungi in two levels (application and non-application) in subplots. The results of four sampling stages showed that application of 30 tons per hectare of manure and application of mycorrhiza in dry matter conditions increased dry matter, relative growth rate and growth rate of crop. Also, after applying stress, physiological indices decreased.
