正常的西瓜多为圆形或椭圆形,但当果实的生长发育受到阻碍时,很容易“长偏”而形成各种不同类型的畸形瓜。西瓜果实“长偏”(畸形)后,其商品性状变差,品质变劣,甚至不堪食用,直接影响经济效益。1.西瓜果实“长偏”(畸形)的原因一是受精不良。据研究,西瓜果实内的种子能产生生长素,刺激果实的发育。瓜内种子发育好而多的部位,果肉发育也好;反之,果肉发育就差。如果开花时遇到低温、降雨,或传
Most of the normal watermelon round or oval, but when the growth and development of the fruit is hindered, it is easy to “long bias” and the formation of a variety of different types of deformed melon. Watermelon fruit “long deviation ” (deformity), the deterioration of their traits, deterioration of quality, or even unbearable, a direct impact on economic efficiency. 1. Watermelon fruit “long partial ” (deformity) one reason is poor fertilization. According to the study, the seeds of watermelon fruit can produce auxin to stimulate fruit development. Melon seed development is good and many parts of the flesh development Ye Hao; the other hand, poor flesh development. If the flowering encountered low temperature, rain, or pass
