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.

At the same time, there was remarkable difference in the calcium distribution on the wall of micropylar canal between self-pollinated and cross-pollinated ovules: abundant calcium precipitates were found on the wall of self-pollinated ovules, whereas none on cross-pollinated pollen.

同时，自交和异交授粉胚珠珠孔道壁钙信号表达也存在很大差异，自交授粉胚珠珠孔道壁有大量钙颗粒密集，而异交授粉胚珠珠孔道壁无钙沉淀积累。
