    • Cucurbits are generally cross pollinated crops.
    • Anthesis and pollination starts in about 40-45 days after sowing.
    • Sequence of flowering follows a set pattern first 4-6 flowering nodes bear the male flower and later female flower.
    • Ratio of male and female 25-30:1 to 15:1 which results in greater number of female f1owers per plant and increase the fruit set percentage. Sex ratio is highly influenced by environment.
    • Abundance of light tends to produce more number of staminate flower and lower light promotes pistillate flowers.
    • High temperature and long days tends to keep staminate phase.
