异源细胞质对小麦籽粒大小和重量影响的初步研究

异源细胞质对小麦籽粒大小和重量影响的初步研究 PRELIMINARY STUDY ON THE EFFECTS OF ALLOCYTOPLASM ON SIZE AND WEIGHT OF WHEAT SEEDS 徐乃瑜 first-author 廖兰杰 刘祖华 在人工整穗和授粉条件下,每穗平均结实率的高低并不明显影响种子的重量。小麦异源细胞质对种子大小和重量有一定影响,其影响大小随细胞质亲缘不同而有异,并与核质互作有密切关系;因而,在籽粒重量方面,如果组合选配得当,可以利用核与质、核与核之间的双重优势;所以核质杂种可能具有生产上利用的实践价值和理论意义。 Under the condition of artificial pruning of ears and artificial pollination, the average percentage of seed set of each ear did not evidently affect the weight of seeds. The alien cytoplasm of wheat certainly influence on the size and weight of seeds, the intensity of influence varied depending on the difference of relationship of cytoplasms, and had close relation with the interactions between nuclear genome and cytoplasmic factor. If compatible combination were chosen between nucleus genotype and cytoplasm, the introduction of alien cytoplasm into wheat had the potential for wheat improvement. There, the nucleo-cytoplasmic hybrids may possess the practical value and theoretical meaning. 异源细胞质 核质杂种 同核保持系 恢复系 核质互作 Allocytoplasm Nucleo-cytoplasmic hybrids Maintainer with same nuclear genome Restorers Interaction between nuclear and cytoplasm 中国科学院科学基金 1987-03-01 2021-04-01 3
