Effect of Sodium Chloride on Growth, Nodulation, Flowering & Yield of Pea Plant (Pisum sativum L.) under Photoperiods

Abstract

Garden pea (Pisum sativum L.) is a popular nutritious vegetable crop grown in winter season through out of the world, belong to family Fabaceae .A study was made on the influence of sodium chloride upon the growth, chlorophyll content, nodulation, flowering and yield of Pea Plant (Pisum sativum L.) CV. P.Arkel under both photoperiod’s i.e. Long day and short days. The finding revealed that plant length, plant fresh and dry weight, leaf no. ,leaf area/ plant, Chlorophyll pigments, carotenoids, root nodules number, root nodules fresh & dry weight, flower number & pod number were higher under long days irrespective to short days in control. No significant effect was observed in the leaf area & photosynthetic pigments with low concentration, while a significant decrease was noticed for each, with two higher concentrations (100,200mM) in photoperiods, ie.SD and LD. As evident from the data, the number of flowers was significantly higher under long days. Salt stress differentially affected the pod yields in both photoperiods. The number of pods was increased 61.5 % in long days, when compare to short days. The long day had more fresh and dry weight of pods in comparison to short days in CV. P. Arkel.
