Abstract

The present study was carried out to investigate the effect of light and GA3 on the germination of purple passion fruit (Passiflora edulis sims) under agro climatic condition of Prayagraj. The perforated polythene bags of 4 x 5 cm size (150 gauges thickness) were used for sowing. The bags were filled with a mixture of farmyard manure (FYM), sand and soil in the ratio of 1:1:1. Pre-sowing-dip method was adopted for seed treatment.The treatments included application of [T0: Shade net(light 20,100), T1: GA3 200 ppm + light 24,500 lux,T2:GA3 200 ppm + light 30,100 lux,T3: GA3 250 ppm + light 24,500 lux,T4:GA3 250 ppm + light 30,100 lux, T5: GA3 300 ppm + light 24,500 lux,T6: GA3 300 ppm + light 30,100 lux,T7:GA3 350 ppm + light 24,500 lux, T8: GA3 350 ppm + light 30,100 lux]. The experiment was laid in randomized block design with nine treatments and was replicated three times. Treatment T8 performed best in term day to 1st germination(20.01), day to 50% germination(26.68), day to complete germination(35.25),germination percentage(89.09), seed vigour index (1400.48),seedling height(10,20,30,40 days) (10.37,11.50,13.69,16.25), number of leaves (10,20,30,40 days) (3.00,4.78,6.22,9.45), shoot length (10,20,30,40 days) (4.68,4.97, 5.05,5.20), root length(10.66), shoot: root(0.62),stem girth(2.70),chlorophyll content (43.37) and survivality percentage(83.65).
