当植物的营养生长达到一定阶段后,在光、温度等因素及内部某些激素的诱导下,在生长锥或叶腋内形成花芽或花序的原基。这标志着植物在进行营养生长的同时进入生殖生长。西瓜的花芽分化是在叶腋内进行的。据报导,西瓜从子叶开展至团棵(4—5片真叶)为幼苗期,此期以幼苗叶的生长建成和结果前期功能叶分化发生为中心,同时在苗端叶腋内开始分化发生生殖器官。早花西瓜品种从播种到开放第1朵雄花需45天。第1个果实发育成熟需30天。早花是目前广泛栽培的早熟品种之一。通过对幼苗的叶和花芽的形态发生和分化过程及它们间的相关性的
When the vegetative growth of plants reaches a certain stage, primordia of flower buds or inflorescences are formed in the growth cone or leaf axils under the influence of light, temperature and other internal hormones. This indicates that plants enter reproductive growth while they grow vegetatively. Watermelon flower bud differentiation is carried out in the leaf axils. It is reported that watermelon from the cotyledon to the trunk (4-5 true leaves) seedling stage, the seedling leaves to the completion of the growth and the results of the early functional differentiation of leaves as the center, at the same time begin to differentiate in the terminal foliage of the seedlings reproductive organ. Early flower varieties of watermelon from sowing to open the first male flowers need 45 days. The first fruit matures for 30 days. Early flowering is one of the earliest cultivars widely cultivated. Through the seedling leaves and flower buds morphogenesis and differentiation process and the correlation between them
