The effect of drought stress during seed development on seed vigour, membrane peroxidation and antioxidant activity in different species of Balangu (Lallemantia sp(

In order to The effect controlled ageing on parameters germination, membrane peroxidation and antioxidant activity the stressed seeds of Balangu (Lallemantia sp), a four- factor factorial study in a completely randomized design with three replications was conducted in laborartory seed science and technology shahed university in 2015. Dragons’ head (Lallemantia iberica) and Lady’s mantle (Lallemantia royleana ), were imposed three drought stress level (control, mild and severe) during seed development and the produced seeds were aged at different seed moisture content( 5, 15 and 25%) for 24 and 48 hours duration). Analysis of variance showed that the interaction effect of species, moisture stress during seed development, duration of aging and seed moisture content on germination percentage, germination rate, mean germination time, membrane peroxidation and catalase activity was significant. It was observed increasing germination percentage and rate germination, mean germination time and catalase activity in the Lady’s mantle stressed seeds and reduced membrane peroxidation and increasing membrane peroxidation and reduced germination percentage and rate germination, mean germination and catalase activity in the Dragons’ head stressed seeds. Were impressed Dragons’ head stressed seed from maternal by more aging were affected by negative effect of aging more than stressed seeds of Lady’s mantle from maternal.
