摘要

Flower bud differentiation on three cultivars of David group of ornamental peach (Prunus persica x Prunus davidiana), which are the pistil abortion cultivar 'Baihua Shanbitao', and two low-yield cultivars 'Pinxia' and 'Pinhong', were studied by the paraffin method. The high fruit yield cultivar 'Jiangtao' was the control. The results showed that pistils of the three studied cultivars developed normally at the initial stage of flower bud differentiation, however, compared with the control cultivar, different types of pistil abortion occurred at the stage of sex cell differentiation, including a thin and deformed style, the stigmatic surface was depauperate and ovule primordial hypoevolutism. It was concluded that the pistil abortion period of 'Baihua Shanbitao', 'Pinxia', and 'Pinhong' started at the sex cell differentiation stage after the formation of the ovary. 'Pinxia' and 'Pinhong' are the F1 progeny of 'Baihua Shanbitao' as their pollen parent, and both inherited the characteristics of pistil abortion from their male parent.
