摘要: 基于油用芍药属植物,从花部综合特征、传粉过程、花粉柱头活性特征、育性特征与受精卵发育命运上对该属植物繁育系统进行了研究。结果发现:1)花粉量超大,花冠硕大,无花蜜,雌性先熟,花枝建成具有母枝大小依赖性;2)甲虫等古老传粉者与高效蜂类传粉者混合而具有过渡性,符合基部被子植物的进化地位,同花期伴生植物蜂类强度大时容易发生盗粉行为;3)花粉活力变异大,存在花粉活性和柱头活性最优期,花粉初级呈现高强度采粉访问和次级呈现低强度搜索访问并存,二者传粉模式不同;4)自交亲和,杂合性在遗传亲缘性越远而越低,合子前障碍为花粉管分枝与胼胝质阻塞;5)胚胎败育可能受到结构资源限制的调节,高产促成要率先考虑结实率,其次考虑败育率。芍药属牡丹组必须适度控制同花期伴生植物种类的访花蜂群规模而不能短时超强度过度采粉,访问高峰期与单花柱头花粉最优活性相吻合,并合理化个体与构件密度,优化营养和生殖关系。芍药属尺度上繁育系统多元系统研究利于粮油潜力量化评估和定向培育技术的系统集成。

Abstract: Studies were made of the reproductive system of oil-used plants of Paeonia L. from their floral sydrome,pollination process,pollen pistill liveness,sexuality and fate of zigote. The results showed that 1) this genus of plants had a large amount of pollen,bigger corolla,no netar,protogeny and size dependency of mother branch during the establishment of flower branch; 2) The pollinators had mixed and transitive features with both age-old beetles and efficient bees and catered for evolutionary status of base angiosperm,and the pollen-stolen behaviour happened while high density bees existed in the acompanying plant species of the same anthesis; 3) The pollen vigour had a big variety,and there could be the optimum time of pollen and pistill activity, the pollen flow coexisted in two different models:primary pollen showing a high density visit to pollen colletion and secondary pollen showing a low density visit to searching nectar; 4) This genus was self-compatible,the lower heterozygosity had a further affinty,and the barrier before the zigote formation was the branching of pollen tube and clogging of callose; 5) The embryo abortion was possibly adjusted by architecture and resource limitation,and for the promotion of high yield the first consideration was the fruit-setting rate,and then the second was the seed abortion rate.
