Effect of NaCl Stress on Pisum sativum Germination and Seedling Growth with the Influence of Seed Priming with Potassium (KCL and KOH)

摘要

Abiotic stress is an important environmental problem limiting crop growth and productivity. Macronutrients such as K+ have ability to overcome stress up to some extent. The study was carried out to investigate the effects of priming with macronutrients K+ as KCl and KOH on Pisum sativum grown under salinity stress condition. Seeds were primed with 250 and 500ppm KCl and KOH and then treated with different concentrations (0mM, 40mM, 60mM and 80mM) of NaCl. Effects of NaCl, KCl and KOH were observed on germination percentage, seedling shoot length, seedling root length, seedling fresh and dry biomass. It was observed that germination and seedling growth (shoot length, root length, fresh and dry biomass) showed reduction in saline conditions. Applications of 250 and 500ppm KCl and KOH showed improvement in above mentioned parameters under saline as well as non-saline conditions.
