摘要

来自许多不同分类群的相容授粉显示非随机交配。在这里,我们描述了一个系统来检查问题的非随机交配拟南芥。利用该系统,我们证明了拟南芥在不同的植株之间表现出非随机交配。对这些数据的统计分析表明,在这些交配中存在花粉竞争和雄性-雌性互补性。细胞学实验暗示花粉萌发和花粉管生长速率可能是这些非随机交配效率的原因。

Incidence and post-pollination mechanisms of nonrandom mating in Arabidopsis thaliana.

Compatible pollinations from many different taxa display nonrandom mating. Here we describe a system for examining questions of nonrandom mating in Arabidopsis thaliana. Using this system, we demonstrate that Arabidopsis thaliana displays nonrandom mating between distinct accessions. Statistical analysis of these data demonstrates aspects of both pollen competition and male-female complementarity in these matings. Cytological experiments implicate pollen germination and pollen tube growth rates as possible causal factors in these nonrandom mating efficiencies.
