Pollen Biological Characteristics of Prunus cerasifera Ehrh.cv.Atropurpurea Jacq.

Zhang Yi (Horticultural Department,Hubei Agricultural College,Jingzhou,Hubei 434025)  
The vitability, storage time and collected time of pollen in Prunus cerasifera Ehrh.cv.Atropurpurea Jacq.and other plums were studied. Prunus cerasifera Ehrh cv. Atropurpurea Jacq. had higher pollen germination rate in low(-4?℃) and higher (22?℃) temperatures( 68.4% and 46.7% respectively) than those of 3 tested cultivars.The germination rate of pollen that was collected from flowers just before blossoming is highest. The pollen of 4 tested types of plums was stored to a average 13.5 days at low temperature(3~5?℃), longer than at room temperature (7?d) without a decrease of vitality to 50%. But the pollen of Prunus cerasifera Ehrh.cv.Atropurpurea Jacq. could be stored longer for up to 18?d and 2?d longer than those of 3 cultivars in the condition of low temperature and room temperature respectively.
