| Abstract: | A study on the effect of maleic hydrazide (MH) on vegetative growth, flowering and yield of bottle gourd (Lagenaria siceraria (Mol) Standl.) was conducted during the rainy and summer seasons of 1979 and 1980, respectively. MH at 150 mg l?1 stimulated the elongation of the main shoot, while MH at 50 mg l?1 induced more branches per plant. Staminate flowers appeared late and at the lowest node number in control plants, whereas MH at 150 mg l?1 had a profound effect on the earliest appearance of pistillate flowers at the lowest node number. Male: female ratio was lowered with MH at 50 mg l?1 and was most effective in producing the maximum number of fruits and fruit weight per plant and ultimately the yield. GA3, NAA and ethrel did not influence yield, while MH did. |
