摘要
该文介绍了杨树 (Populusspp .)生殖生物学的研究概况 ,包括 :①杨树有性生殖过程中雌雄生殖系统形态结构和细胞化学变化及其生物学意义 .②雄性不育的机理 .③杨树杂交不亲和性的表现和原因及其克服的方法 ,花粉-柱头识别反应 .④杨树生殖工程取得的成就 .
In this article, the advances in reproduction biology of poplars are reviewed in four respects as follows: ①The morphological and cytochemical changes and the biological significance of female and male reproductive systems in sexual reproduction of poplars; ②The mechanism of male sterility in poplars; ③The reasons and descriptions of cross incompatiblity in poplars, the methods to overcome the cross incompatibility and the stigma pollen recognition reaction; and ④The progress made in reproductive engineering in poplars.
