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 artificial whole-spike and pollination conditions, the average seed setting rate per panicle did not significantly affect seed weight. Heterologous cytoplasm of wheat has certain influence on the size and weight of seeds, the size of the cytoplasm depends on the relatives of cytoplasm, and is closely related to the interaction of nuclei; therefore, if the combinations are properly selected, the nuclei can be utilized And the dual advantages between quality, nuclear and nuclear; so the nuclear hybrids may have practical value and theoretical significance for their utilization in production.
