Effect of plant growth regulators on quality, yield and growth of bottle gourd [Lagenaria siceraria (Molina) standi.]

摘要

Bottle gourd cv. Warad (MGH4) with three growth regulators having three concentration NAA (80,100 120ppm), GA3 (20,40 & 60ppm) and Ethrel (5,10 & 20ppm). The growth regulators were sprayed at four lei stage and pre flowering stage. Growth regulator NAA lOOppm was found most effective treatment, i. vine length (8.85m), Number of node to first male flower appearance (7.86), Number of node to first fema flower appearance (8.69), Number of male flowers per vine (49.35), No. of female flowers per vine (18.85 days to initiation of first male flower (59.20), days to initiation of first female flower (60.81), diameter ( fruit (17.34cm), highest fruit length (43.53cm), fruit weight (1.549kg), Number of fruits per plant (10.82 fruit yield per plant (17.759kg), total fruit yield (65.48t/ha), Ascorbic acid (11.19mg/100g), T.S.S (18.15°Bri: and seed-pulp ratio (1:10.18).
