目前世界上各国生产无籽西瓜均采用三倍体获得无籽的方法。由于这一方法制种困难,而且采种率低,发芽率低,成苗率低,因而加大了生产成本,降低了经济效益。为了克服三倍体无籽西瓜的缺陷,早在1937年日本就开始试验用激素来处理西瓜雌花柱头,使之单性结实,从而得到激素无籽西瓜。但由于使用方法上的缺点,成瓜数少,畸形瓜多,品质也较
Currently, seedless watermelons are produced in all countries in the world using triploidy methods to obtain seedless seeds. Because of this method of seed production difficulties, and the low seed rate, low germination rate, low seedling rate, thus increasing the cost of production and reduce economic efficiency. In order to overcome the shortcoming of triploid seedless watermelon, as early as 1937, Japan began to test the treatment of the stigma of watermelon female with stigma to make the hermaphrodite strong, so as to obtain the hormone seedless watermelon. However, due to the shortcomings of the use of methods into a small number of melons, melon deformity, quality is better
