Abstract
Distant hybridization compatibility between peach [Primus persica (L.)Batschj and plum(P. salicina Lindl.) was studied with a fluorescent microscope and paraffin slice method. The results showed that the fertilization rate and fruit set rate were about 3% when peach used as female parent. Plum pollen germinated normally on the stigmas of peach. Pollen lubes developed slowly after they got the middle of style, most of them couldn' t get to the ovule and fertilized. This is the main reason of incompatibility between peach and plum.

Claim · model-written summary
The authors attribute peach–plum incompatibility to slow pollen tube growth and failure to reach the ovule.
