Abstract

Germination per cent and growth of ML 267 and ML 131 cvs of mungbean (Vigna radiata Wilzec) seedlings was adversely affected by high temperature stress (42°C). Pre-sowing seed soaking in fluridone (flu) significantly increased germination per cent and seedling growth at both normal and high temperatures. Total free sugar accumulation was significantly increased under stress and Flu pre-treatment significantly increased it, both at 30° and 42 °C. Enzyme activities of α- and β-amylases were found correlated with increased accumulation of sugars under stress. Flu pre-treatment partially ameliorated the effects of heat stress.
