研究厚皮与薄皮两类不同生态型的甜瓜表明：甜瓜两子叶一心时便开始花芽分化，３—４真叶后分化显著加快。第１子蔓较第２子蔓分化慢，生长势弱。花芽按萼片→花瓣→雄蕊→雌蕊向心分化，各分化期与花原基大小相关。分化之初花原基无性别差异，当长为０．６—０．７毫米时可鉴别雌雄。最初，每节具花原基２—８个或更多，但雌花节仅一个原基得以发育，其他退化。出雌率，孙蔓＞子蔓＞主蔓。薄皮甜瓜达到同样生理苗龄的时间比厚皮甜瓜短，花、叶、茎分化快；但生理苗龄相同时，后者较前者的分化数多。
The study of two types of muskmelon with different ecotypes showed that when two cotyledons of melon began to flower, differentiation of flower buds began to occur, and the differentiation of 3-4 true leaves was significantly accelerated. The first submanus than the second submanifferentiation slow, weak growth. Flower bud sepals → petals → stamens → pistil to the heart of differentiation, the differentiation of the flower base size. Differentiation at the beginning of the flower base no gender differences, when the length of 0.6-0.7 mm can identify male and female. Initially, each flower has 2-8 or more primordia, but only one primordial female flower node develops, others degenerate. A female rate, Sun Man> Sub-Man> Lord Man. Thin muskmelon to achieve the same physiological age of seedlings shorter than the muskmelon, flowers, leaves, stems quickly differentiated; but the same physiological age, the latter more than the former number of differentiation.
