Abstract

This experiment was conducted in order to investigate the morphological and physiological responses ofvetiver grass (Chrysopogon zizanioides L. Roberty), to water deficit stress and salicylic acid applicationat Department of Horticultural Sciences, University of Zanjan in 2015. After 6 months of plantingtransplants into pots, three soil AVAILABLE WATER levels (40, 70 and 100%) and salicylic acid concentrations(0, 1 and 2 mili Molar) were applied in a factorial experiment based on completely randomized designwith three replications for six weeks. Salicylic acid applied through foliar spray weekly. Generally, waterdeficit reduced root and SHOOT DRY WEIGHT and leaf chlorophyll content. Root length, TOTAL PHENOL, prolineand electrolyte leakage of leaves were increased by reducing the amount of AVAILABLE WATER. Salicylic acidapplication improved negative effects of water deficit in all attributes and its effect was more pronouncedin 40% AVAILABLE WATER treatment. In all AVAILABLE WATER levels, there was no significant differencebetween 1 and 2 mili Molar salicylic acid treatments in root dry weight and leaves TOTAL PHENOL whereas inother factors. 2 mili Molar salicylic acid application had better result and plants in this treatment hadhigher SHOOT DRY WEIGHT, proline and chlorophyll content and less electrolyte leakage than 1 mili Molarsalicylic acid treatment, suggesting that in order to increase water deficit TOLERANCE of vetiver grass, higherconcentration of this plant growth regulator must be evaluated.
