1.After a flower has been open for a time the anthers and stigmas may come together allowing selfing if there has been no cross-pollination.
花开放一段时间后，如果不能异花受粉，它的花药和柱头就可以接触进行自交。
2.The production of weak offspring as a result of selfing, inbreeding depression, may be hard to distinguish from late-acting SI systems.
因为自交产生的后代较差（自交衰退），因而很难与后作用SI系统区分开来。
3.The commonest form of inhibition of selfing is some form of physiological self-incompatibility (SI) system.
抑制自交最常见的形式是生理上的自交不亲和系统。
4.Most seed orchard theory is based on the assumption that panmixis will occur and that selfing will not be a serious problem.
大多数关于种子园理论，是以假定能发生随机交配和自花受精而不会成为严重问题为依据的。
5.Homozygous races do not segregate on selfing.
自体受精不能分离纯合的生理小种。
6.On selfing or crossing heterozygotes some double recessives may appear, giving viable offspring.
在自交或杂交产生的杂合子中双隐性性状可以表现出来并产生可育后代。
7.The fertility of newly found sterile plants "3213A" was studied by cross, reciprocal -cross, selfing and test -cross methods.
以新发现的天然不育株3213A为材料，采用正反交、自交和测交等方法，分析研究其后代的育性分离表现。
