结果表明：风味皇后和恐龙蛋2个杏李品种的自花授粉坐果率均为0，说明2品种自花不实，属异花结实果树。

These results suggested that internal hormone content and balance of pistil tissue and young fruits might be related with final effect of pollination and fertilization after self-pollination among different pear culturals.

这表明不同梨品种自花授粉后雌蕊组织及幼果中的内源激素含量及其平衡状态可能与最终的授粉受精效果有关。

The results showed that: pollen tube grew normally and entered into the style base after self-pollination of self-compatible cultivar and cross-pollination of self-incompatible cultivar.

Self-pollination, in general, produces lower percentages of seeds than controlled cross-pollination.

与自然传粉和杂交控制传粉相比，自花传粉常常导致较低的结实率。

Furthermore, our study can provide valuable references for the pollen-mediated gene flow in other self- and wind-pollination crops, such as wheat, for the pollen-mediated gene flow models of wind-pollination crops may follow the same principles.

特别是花粉介导的基因漂移模型的一般形式，在风媒传粉作物间应该是一致的。

Our study can provide valuable references for the pollen-mediated gene flow in other self- and wind-pollination crops, such as wheat, for the pollen-mediated gene flow models of wind-pollination crops may follow the same principles.

特别是花粉介导的基因漂移模型的一般形式，在风媒传粉作物间应该是一致的。

Self-pollination was brought as the essential reason for causing emptied seeds by former researchers. Based on those studies, potassium antimonate and electron microscopy were used to study the calcium distribution of pollens in the micropylar canal of self-pollinated and cross-pollinated ovules and morphological changes in certain cells undergoing programmed cell death from pollination to fertilization, and observation of histo-chemical changes during microgametopyte development was performed by paraffin section.

前人研究认为自交是华北落叶松产生空粒的主要原因，本论文在此基础，运用焦锑酸钾沉淀法配合电镜观察研究了传粉后到受精前异交控制和自交辅助授粉胚珠珠孔道内花粉的钙分布情况，及此过程中细胞程序化死亡超微结构的变化，并通过石蜡切片研究了华北落叶松传粉后到受精前雌配子体发育过程及细胞内含物的变化，以研究在受精前胚珠内是否存在花粉识别与选择系统，探讨钙信号传导和花粉与胚珠相互作用及细胞程序化死亡的关系。

The nectaries of Ensete glaucum had the highest starch content, and those of Musa basjoo and E. glaucum had fibrillar material presented in nectar ducts. Pollination syndromes among the three species showed high diversity, while inflorescence and flower characters (such as pendant or erect inflorescences, bract color, nectar volume and production over time, etc.) and pollination patterns were highly correlated.
