Abstract

In order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the Research Center of Plant Sciences in Ferdowsi University of Mashhad. The first factor was different levels of methanol including, 0 (control), 20, 25, 30, 35 volumetric percentage (v/v), which were used as foliar applications at three times during growth season of chickpea, with 10 days intervals. Second factor was drought stress condition in two levels 25 and 100 percent of field capacity. Results showed that there was significant difference (P‌AWT IMAGE0.01) between methanol levels concentrations regarding to leaf protein content, proline content, total soluble sugar, H2O2 content, catalase, peroxidase and SOD enzyme activity. Spraying with 30% volume level significantly increasedleaf protein, proline and total soluble sugar content compared to control. Effects of drought and methanol were not significant on antioxidant enzyme activity, leaf protein content, total soluble sugar and H2O2 content but on the proline content was significant (P‌AWT IMAGE0.05).

Abstract

Organic fertilizers are a source of very useful for improving soil quality and yield of various crops. Vermicompost and derived products such as compost tea as a product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of various environmental stresses on plants. In order to evaluate the effects of compost tea on some morphological characteristics of lentil under water deficit stress, a factorial experiment was conducted factorial based on completely randomized design with three replications in 2015 at the Khatam Alanbia University of Behbahan. The first factor was different levels of compost tea including, 0 (control), 25, 50 and 75 volumetric percentage and second factor was water stress in three levels, 25, 50 and 100 field of capacity. Foliar application of compost tea was applied 3 times during plant growth stage (seedling, flowering and podding). Results showed that there was significant difference (p 0.01) between vermicompost levels concentrations regarding to plant height, number of branches, leaf number per pod, root and shoot dry weight, taproot length, root diameter, root volume, root area and number of pod. Foliar application of compost tea, for most traits of shoot compared to the control group increased significantly but in the root characteristics under moderate and severe water stress, there was no significant difference between treatments. Considering that, compost tea contains many of the growth regulators and micro and macro element will be introduced as an appropriate fertilizer to increase morphological parameters.
