无籽西瓜又叫三倍体西瓜。它的栽培技术基本上与普通西瓜(二倍体西瓜)相似,但由于它的某些植物学特征和生物学特性与普通西瓜不同,所以在栽培上也有所差别,其要点如下: 一、播种选种和种子处理 无籽西瓜在制种过程中,可能会混杂一些二倍体、四倍体西瓜的种子,因此在播种前要进行一次严格的粒选。各类型西瓜种子特征是:二倍体西瓜种子,形态较小,珠眼不突出,脐部较窄,种壳无纵裂;三倍体西瓜种子,种胚不充实,珠眼突出,种壳表面常凹陷不平,并有较深的木栓质纵裂;四倍体
Seedless watermelon also known as triploid watermelon. Its cultivation technology is basically similar to that of ordinary watermelon (diploid watermelon), but due to its different botanical and biological characteristics, it differs in its cultivation. The main points are as follows: I. Sowing Seed selection and seed treatment Seedless watermelon in the seed production process, may be mixed with some diploid, tetraploid watermelon seeds, so before sowing to conduct a rigorous pelleting. The characteristics of each type of watermelon seeds are: Diploid watermelon seeds, small shape, beads are not prominent, narrow umbilical, seedless longitudinal slits; triploid watermelon seeds, seed embryo is not full, Surface often depressed, and deep cork longitudinal split; tetraploid
