Interspecific compatibility and incompatibility have been examined through the genus Populus. General methods of manipulation have been developed to break the incompatibility barriers. These methods are described and a hypothesis is put forward to account for the results. This proposes that at least two factors are involved, one attached to the pollen (P) and one to the stigma (S), and that the interaction of these (PS) is critically involved in the total process. Implications for future plant breeding are discussed.
通过杨属植物研究了种间亲和性和不亲和性。已经开发出打破不亲和性障碍的一般操作方法。本文对这些方法进行了描述，并提出了一个假设来解释结果。该假设认为至少有两个因素参与其中，一个与花粉（P）有关，另一个与柱头（S）有关，这些因素的相互作用（PS）对整个过程至关重要。讨论了对未来植物育种的影响。
