摘要
介绍了有关梨树的生殖生物学的研究概况,具体包括:梨树有性生殖过程中雌雄生殖系统形态结构、发育变化情况和受精过程;雄性不育的机理;梨树自交不亲和性的分子机理和S-基因型的鉴定。
The researches on reproductive biology of pear were reviewed in three respects, and its were as follows： morphological structure, development changes of female and male reproductive systems and the whole process of fertilization during sexual reproduction of pear ; the mechanism of male sterility; the molecular mechanism of self-lncompatibility and identification of S-genotypes in pear.
