Abstract

Rapid germination is an important factor determining the final yield. This study was performed to investigate the effects of different levels of methanol and drought stress on germination characteristics of lentil seedlings. The experiment was conducted in completely randomized design with three replications in summer 2014 at the Khatam Alanbia University of Behbahan. The first factor was different levels of methanol equal to 0 (control), 5, 10 and 15 volumetric percentage (v/v), and the second factor we negative water potential in four levels 0, -3, -6 and -9 bar by PEG. Results showed that there was a significant difference between different methanol concentrations regarding germination percentage, germination speed index, plumule and radical length, plumule and radical dry weight, radical area, radical diameter and consumed endosperm (P 0.01). Different levels of methanol caused a significant decrease in germination characteristics compared with to control. Drought stress with -9 bar level significantly decreased germination percentage, germination speed index, plumule and radical length, plumule and radical dry weight, radical area, radical diameter and consumed endosperm compared to other levels. Effects of drought and methanol were significant differences regarding the germination speed index, plumule length, plumule dry weight and consumed endosperm (P 0.05).

Abstract

This study was performed to investigate interactions of different levels of vermicompost extract and salinity stress on germination characteristics of chickpea seedlings. The factorial experiment was conducted in completely randomized design with three replications. Concentrations of vermicompost extract (0, 5, 10 and 20 volumetric percentage) and salinity levels (0, 30, 60 and 90 mM NaCl). Results showed that there were significant differences (P‌ 0.01) between vermicompost extract and salinity levels regarding germination percentage, radicle length, and shoot dry weight. Salinity stress with 90 (Mm NaCl) level significantly decreased all of the traits compared to the non-stress condition. Effects of vermicompost extract and salinity stress were significant differences (P‌ 0.05) on the germination rate index, radicle length, radicle dry weight and consumed endosperm. vermicompost extract at concentrations of 5 volumetric percentage in moderate salinity stress (30 mM NaCl) and non-salinity stress caused a significant increase (P‌ 0.01) in radicle length, radicle dry weigh and consumed endosperm compared to control.
