| Abstract:
The effect of growth regulators (Ethrel, MH and IAA) on summer squash cv. Mullah Ahmed was studied. Applied growth regulators suppressed staminate flowers, enhanced pistillate flower development, lowered the node position of first pistillate flowers, increased the number of pistillate flowers, and increased the pistillate to staminate flower ratio. Ethrel was more effective than both MH and IAA. Total yield increased by the application of growth regulators compared to control. In general IAA at 200 ppm was more effective in increasing the total yield as compared to control. | |
