Growth and development characteristics of seedless watermelon

First, the self-flowering is not fruitful, so it needs to be pollinated. The male and female gametes of female and male flowers of seedless watermelon are abnormal, the pollen of male flowers has no vitality, and can not stimulate the development and expansion of female ovary after pollination, so it is difficult to set fruit. Second, it has obvious hybrid advantage. Triploid seedless watermelon is a hybrid of tetraploid and diploid watermelon. therefore, triploid seedless watermelon plants show exuberant growth, strong resistance and high demand for fertilizer and water in the field.
