无籽西瓜种子与普通二倍体西瓜种子相比,结构上具有种皮厚、种脐坚硬、种胚发育不全、种腔大等特点。决定了其种子在萌发过程中对发芽条件具有特殊要求。若采用普通二倍体西瓜种子发芽技术,对无籽西瓜种子进行催芽,其发芽率仅为20%～30%,而且芽势不整齐。导致生产上培育壮苗难,生产成本高。严重制约了无籽西瓜在生产上的大面积发展。针对上述问题,笔者从无籽西瓜种子的生理特点入手,实践总结出一
Compared with common diploid watermelon seeds, seedless watermelon seeds have the characteristics of thick seed coat, hard umbilicus, hypoplastic embryogenesis and large seed cavity. Determined that the seeds in the germination process on the germination conditions have special requirements. If using ordinary diploid watermelon seed germination technology, seedless watermelon seeds germination, the germination rate of only 20% to 30%, and the buds are not regular. Lead to strong seedling production difficulties, high production costs. Severely restricted the large-scale development of seedless watermelon production. In response to the above problems, the author start from the physiological characteristics of seedless watermelon seeds, the practice summed up a
