Nanoemulsion seed coating for heat stress management in soybean

Abstract

An experiment was conducted to access the effect of methyl cellulose nanoemulsion seed coating in soybean (JS-93-05) against heat stress. The nanoemulsion was prepared by using methyl cellulose, vitamin E and tween 80 (in the form of oil in water) with the help of high energy homogenizer. The properties of nanoemulsion were characterised by using Particle size analyzer. (PSA), Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). Soybean seeds e coated with nanoemulsion @ 20ml/kg and kept in plant growth chamber where the temperature and relative humidity were maintained at 400C and 50% for a duration of 0, 3, 5, 7, 9, 11 and 13 days and simultaneously seed quality was determined. The results demonstrate that nanoemulsion coated seeds recorded higher rate of germination, speed of emergence, seedling length, vigour index and root volume compared to uncoated seeds under high temperature stress condition.
