萌发

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

Therefore,foliar spraying ofboron was the main measure during flowering period so as to stimulate thegermination and growth of pollen tube,regulate endogenous hormone balance ofovary and promote gynospore formation and,during the phase of young embryodevelopment,spraying of relevant plant growth regulators and potassiumsupplement were essential to stimulating the increasing of endogenous GA1/3 andiPAs,raising the key nutritious substance content in ovary and promoting youngembryo development.

因而花期调节以喷B为主，以便促进花粉管萌发生长，调节子房内源激素平衡，促进大孢子形成；幼胚发育期以植物生长调节剂喷布和K素补充为主，以便启动子房内源GA1/3、iPAS等上升，增加还原糖、淀粉、蛋白质积累和K素吸收，促进幼胚发育。
