What to Do When Watermelon Plants Do Not Set Fruit? Analysis of Climate and Other Causes
Watermelon Fruit Set Failure Caused by Climate and Other Factors
(Agricultural Wealth Network) Causes of fruit set failure due to climate and other factors: First, poor flower bud differentiation. There are male flowers but no female flowers, or female flowers but no male flowers, or the anthers of male flowers cannot dehisce normally, with no pollen or low pollen fertility. Second, the influence of rain. If the flowering period encounters overcast and rainy days or rain every few days, with too much water, weak light and delayed management, normal pollination and fertilization are affected. Third, reduced pollen activity. Watermelon male flower pollen is extremely prone to drying out, losing water and shedding, losing activity, and cannot pollinate or fertilize.
