无籽西瓜具有生长势强、抗病、含糖量高和食用方便等特点,深受广大城乡居民欢迎。但是无籽西瓜是三倍体,其细胞染色体与二倍体普通西瓜不同,因而有不同于二倍体普通西瓜的特征和特性;在栽培管理上也有所不同。因此在栽培无籽西瓜时应注意以下问题。一、种子“破壳” 无籽西瓜种皮厚,尤其是种胚部位更厚,种胚又不饱满,发芽困难,所以必须机械破壳才能顺利出芽。种子消毒处理后,浸种8~10小时,捞出晾干种子表面水分,将种子竖立,用克丝钳嗑开种脐后方可催芽。二、种子催芽和育苗温度要高无籽西瓜发芽要求的温度比二倍体西瓜
Seedless watermelon with strong growth potential, disease resistance, high sugar content and easy to eat and other characteristics, welcomed by the majority of urban and rural residents. However, seedless watermelon is a triploid, its chromosomes are different from ordinary diploid watermelon, and thus have different characteristics and characteristics of diploid common watermelon; in the cultivation and management are also different. Therefore, when cultivating seedless watermelon should pay attention to the following questions. First, the seed “broken shell ” Seedless watermelon seed coat thick, especially the embryo site thicker embryo and not full, germination difficulties, it must be mechanical broken shell in order to smooth budding. Seed disinfection, soaking seed 8 to 10 hours, remove and dry the surface of the seeds of water, the seeds erected, with Kesi 嗑 open umbilicus before germination. Second, seed germination and seedling temperature is higher Seedless watermelon germination requires temperature than diploid watermelon
