Abstract:

To investigate the biological characteristics of flowering and pollination of Prunus salicina Lindl.cv.‘Fengtangli’ and provide a theoretical foundation for floral management and pollinizers allocation in the field, ‘Fengtangli’ and its pollinating cultivars ‘Siyueli’, ‘Fenghuangli’, and ‘Yinhongli’ were utilized as the materials. The flowering phenology, pollen quantity, pollen viability of ‘Fengtangli’ and its pollinating cultivars, and stigma receptivity of ‘Fengtangli’, as well as the fruit set rate of ‘Fengtangli’ with different pollination combinations and different exogenous treatments were investigated. The results showed that the flowering period of the four test cultivars were consistent and overlapped with each other. The pollen quantity ranged from 504.76 to 1 622.64 grains. The pollen germination rate ranged from 34.47% to 51.22%, and the pollen viability was ranked as ‘Fenghuangli’>‘Siyueli’>‘Yinhongli’>‘Fengtangli’. The stigma receptivity of ‘Fengtangli’ was the strongest on the day of flowering. The highest fruit set rate was recorded in ‘Fenghuangli’ pollinated flowers (49.56%), while the lowest fruit set rate was observed in self-pollination (12.20%), indicating that ‘Fengtangli’ and ‘Fenghuangli’ had the highest pollination compatibility and ‘Fengtangli’ was self-compatible. In conclusion, the suitable pollinizers for ‘Fenghuangli’ in this experiment were: ‘Fenghuangli’>‘Siyueli’>‘Yinhongli’>‘Fengtangli’. In addition, spraying boron during flowering could effectively improve the fruit set rate of ‘Fengtangli’.
