Abstract

The experiment was carried out to examine the impact of different concentrations of exogenously applied of epibrassinolide (e-BL) and zinc (Zn) on the physio-biochemical processes of garden pea (Pisum sativum L.) under subjected waterdeficit stress environment.

A polyhouse experiment was performed using completely randomized design with three replications by e-BL pre-treating the seeds of garden pea genotype HUP-2 with concentrations of 0.01 and 0.05 mM and/or Zn before subjecting the plants to an induced water deficit stress at various stages of growth and development.

Garden pea seeds that had been pre-treated with e-BL and Zn micronutrients showed a favorable reaction against a water shortage condition in terms of membrane stability and a variety of enzymatic activity. It is possible for e-BL and Zn to mitigate the impact of post-anthesis water shortage, which is more likely to result in yield reduction. Both seed pre-treatment with e-BL and basal administration of Zn have shown to be effective in protecting the HUP-2 genotype of Garden pea from the negative impact of water deficiency.
