EFFECT OF TEMPERATURE ON GERMINATION, FLOWERING AND POD FILLING STAGES OF MUNGBEAN GENOTYPES (Pages : 1 - 4)

Climate is changing and air temperature is rising due to increasing concentration of CO2 and other atmospheric greenhouse gases. The rise in atmospheric temperature causes detrimental effects on growth, yield, and quality of the crop varieties by affecting their phenology, physiology, and yield components. The effect of different temperature on four mungbean genotypes (MM-8, MI-12, Binamoog-8 and Binamoog-11) was investigated at germination, flowering and pod formation stage to find out temperature tolerant genotype. Germination of the mungbean genotypes was investigated under different temperature levels (20, 25, 30, 35 and 400C). The experiment was laid out in CRD with three replications. The highest germination (97.16%) of mungbean genotypes was found in 300C followed by 350C (94.25%). MM-8 and MI-12 showed the highest germination (97.00%). Binamoog-11 produced shorter root whereas Binamoog-8 had shorter shoot. The mungbean genotypes were again investigated under high temperature (380C) at flowering and pod filling stage for 3 days in plant growth chamber along with ambient temperature. The experiment was laid out in RCBD with three replications. High temperature (380C) at flowering and pod filling stage significantly decreased yield and yield attributes. MM-8 produced the highest seed yield followed by Binamoog-11 under the temperature treatments.Download
