新白凤桃为雄性败育品种的主要授粉品种之一，其大部分花粉能育，败育花粉占８％～３７．７％。花粉败育与药壁绒毡层无关。导致花粉败育的主要因素是由于花粉母细胞的不正常减数分裂，致使在减Ⅱ末期出现多于４核的大小不一的多核现象。在四分体时期，这些核被分配到４个子细胞中，因此部分子细胞中具２～３核现象。由异常减数分裂所产生的花粉粒，其细胞质和细胞核解体消失，而呈现空囊状的孢壁，或具细胞质和核的异形花粉。 New Baixian peach is one of the main pollination varieties of male abortion varieties, most of which pollen fertile, abortion pollen accounted for 8% to 37.7%. Pollen abortion has nothing to do with the tapetum. The main cause of pollen abortion is due to the abnormal meiosis of pollen mother cells, resulting in more than 4 nuclei in different sizes and multinucleation at the end of stage II. In the quartet, these nuclei are distributed to four daughter cells, so some of the daughter cells with 2 to 3 nuclear phenomenon. The pollen grains produced by abnormal meiosis disappear from the cytoplasm and nucleus and present empty cystic spores or irregularly shaped pollen with cytoplasm and nucleus.
