摘要:

【目的】在库尔勒香梨授粉液中添加几丁聚糖,研究植物免疫诱抗剂几丁聚糖对花粉活力、香梨树坐果率及果实品质的影响,筛选出最佳的几丁聚糖喷施浓度,为生产上合理利用几丁聚糖提高香梨坐果率及改善果实品质提供理论依据。【方法】以授粉花粉(鸭梨花粉)与库尔勒香梨树为试材,采用花粉离体萌法和田间人工液体授粉法,研究7个浓度的几丁聚糖处理下授粉花粉活力、香梨坐果率及果实品质的变化。【结果】几丁聚糖浓度在0.25~1.25 mL/L时能够提高花粉萌发率、坐果率及改善果实品质,几丁聚糖浓度达到2.50~5.00 mL/L时会导致花粉萌发率、坐果率及果实品质的下降。0.5 mL/L几丁聚糖在提高花粉萌发率和坐果率的同时改善香梨品质。【结论】香梨授粉液中以添加0.5 mL/L几丁聚糖为最适用量。

Abstract:

【Objective】 By adding chitosan to the pollination solution of Korla Fragrant Pear, the effects of plant immune inducer chitosan on pollen viability, fruit setting rate and fruit quality of Korla Fragrant Pear were investigated, and the most suitable concentration of chitosan was screened out in the hope of providing a theoretical basis for the rational use of chitosan in production to improve the pollination efficiency and fruit quality of Korla Fragrant Pear.【Methods】 With pollinated pollen (Yali pear pollen ) and Korla Fragrant Pear tree as test materials, pollen in vitro germination method and field artificial liquid pollination method were used to study the changes of pollinated pollen vitality, fruit setting rate and fruit quality of Korla Fragrant Pear treated with 7 concentrations of chitosan.【Results】 When the concentration of chitosan was 0.25-1.25 mL/L, the pollen germination rate, fruit setting rate and fruit quality could be improved, and 0.5 mL/L was the best.Through independent analysis of each quality index and principal component analysis of fruit quality, it was concluded that 0.5 mL/L chitosan improved the quality of Korla Fragrant Pear while increasing pollen germination rate and fruit setting rate.【Conclusion】 It is recommended to add 0.5 mL/L chitosan as the most suitable amount in the pollination solution of Korla Fragrant Pear.

Key words: Korla Fragrant Pear; chitosan; pollination; fruit setting rate; quality
