以3个杂交水稻品种的商品种子为材料,研究了裂颖和裂纹对杂交水稻种子发芽和幼苗生长的影响。结果表明,杂交水稻种子普遍存在裂颖和裂纹现象,种子裂颖率和裂纹率都较高;与非裂颖和非裂纹种子相比,裂颖和裂纹种子发芽势和发芽率降低,幼苗素质较差;裂颖对种子发芽势和发芽率的影响大于裂纹,而糙米裂纹对幼苗生长的影响大于裂颖。
The commercial seeds of three hybrid rice varieties were used as materials to study the effects of crack and crack on germination and seedling growth of hybrid rice. The results showed that there were common crazing and cracking phenomena in hybrid rice seeds, and the seed cracking rate and the cracking rate were high. Compared with non-split and non-cracked seeds, the germination potential and germination rate of cracked cracked and cracked seeds were decreased, Poor; crack Ying on the seed germination potential and germination rate greater than the crack, and brown rice crack growth on seedlings greater than crack Ying.
