effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...

in this study, the effect of drought stress on morphological and physiological characteristics of wheatgrass and tall fescue was investigated in a factorial-split plot in time arrangement based on a completely randomized design with three replications. after turf establishment, half pots were exposed to drought stress and the half other were completely irrigated. based on the results tall fescu...

in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted taking into account three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), drought stress of three levels (irrigated at 5, 10 and 15 days intervals) and two olive cultivars (mary and mission) in a factorial experiment based on ra...
