ABSTRACT

An experiment to know GA, NAA and Ethephon's (plant growth regulators) influences in vegetative, flowering and fruiting of strawberry was carried out in November, 2005 to February, 2006 at Kakani of Nuwakot district in RCBD design with ten treatments and four replications. The vegetative parameters were significantly affected by GA at its all concentrations. Among which GA 150 ppm showed the highest value of plant height (39.5 cm) and leaf number (11.7), whereas GA 100 ppm gave the longest petiole (7.9). NAA (20 and 50 ppm) also produced significantly longer petiole length. GA 50 ppm and NAA 20 ppm showed the highest flower number (20.54) and fruit number (16.3) respectively. Both fruit yield and fruit size improved with GA 50 ppm as compared to other treatments. Ethephon did not give visible significant increase over control; rather it produced inferior fruit with reduced vegetative growth.
