摘 要:【目的】采用不同植物生长调节物质处理蓝果忍冬植株,探究植物生长调节物质对果实脱落以及果实品质的影响,筛选出蓝果忍冬最适植物调节剂施用浓度,为蓝果忍冬栽培生产提供理论依据。【方法】以蓝果忍冬蓓蕾品种为试材,选取不同浓度2,4-二氯苯氧乙酸(2,4-D)、赤霉素(GA_(3))、乙烯利(ETH)和脱落酸(ABA)处理植株,对果实脱落率进行统计,并于果实成熟期测定果实外观品质及营养成分。【结果】GA_(3)和2,4-D处理蓝果忍冬蓓蕾果实脱落率的每次统计结果均小于对照,ABA和ETH浓度不同对脱落影响不同。50 mg·L^(-1)的GA_(3)处理后果实单果质量、果形指数、硬度均显著高于对照,可溶性固形物含量与总酸含量显著增加,在改善外观品质的同时增加了蓝果忍冬果实风味。在功能成分总酚、黄酮类化合物、总花青素含量的指标测定中,各种类型植物生长调节物质的不同浓度处理,其作用结果不同。【结论】100 mg·L^(-1)的2,4-D、50 mg·L^(-1)的GA_(3)处理是延缓果实成熟脱落的最佳选择,100 mg·L^(-1)的ABA和50 mg·L^(-1)的ETH处理是促进果实成熟脱落的最佳选择,其中50 mg·L^(-1)的GA_(3)处理提高果实品质效果最好。【Objective】Fruit abscission is a major limiting factor in the production of blue honeysuckle(Lonicera caerulea L.).Cultivars with different maturity periods can cause economic losses during mechanical harvest.Plant growth regulators can regulate fruit abscission and quality.However,the effects of plant growth regulators on fruits in blue honeysuckle remain largely unclear.In this work,we explored the effect of 2,4-dichlorophenoxyacetic acid(2,4-D),gibberellin(GA_(3)),ethephon(ETH)and abscisic acid(ABA)with different concentrations on fruit abscission and quality of blue honeysuckle,and screened the most suitable spraying concentrations for blue honeysuckle production.Our research will provide theoretical basis for high quality and efficient cultivation of bule honeysuckle and increase economic benefit.【Methods】Berel,a main cultivar in China was selected as the experimental material.The leaves of Berel were sprayed with different concentrations of 2,4-dichlorophenoxyacetic acid(25mg·L^(-1),50 mg·L^(-1),75 mg·L^(-1),100 mg·L^(-1) 2,4-D),gibberellin(25 mg·L^(-1),50 mg·L^(-1),75 mg·L^(-1),100mg·L^(-1)GA_(3)),ethephon(50 mg·L^(-1),100 mg·L^(-1),150 mg·L^(-1),200 mg·L^(-1) ETH)and abscisic acid(50mg·L^(-1),100 mg·L^(-1),150 mg·L^(-1),200 mg·L^(-1) ABA).Water was used as the control(CK).For each treatment,three plants with the same growth potential and without pests and diseases were used.The plants were sprayed once every 7 days,a total of 4 times.Three branches in different directions of each tree were selected to calculate abscission rate,and the number of fruits was investigated every five days from the fruit expansion period.The mature fruits with different treatments were randomly selected for fruit quality measurement experiments.We investigated the appearance indicators(fruit weight,vertical diameter,horizontal diameter,hardness)and nutrient contents(soluble solids,total acid,chlorophyll,total phenols,flavonoids,anthocyanin,soluble pectin,propectin)of the fruits.In addition,SPSS software
