不同类型果袋对“中梨1号”梨果点性状的影响

Effect of different types of bag on fruit dots traits of Zhongli No.1 pear

为探究6种不同类型果袋套袋对“中梨1号”果点的影响,以不套袋为对照,对成熟期各处理果实单果质量、可溶性固形物、糖酸及果形指标等进行测定,并观察、测定不同处理的果点大小、果点密度、果点凹凸、果点显隐性状。结果表明,套袋后,“中梨1号”梨果面果点变小,果点凸值明显降低,果点颜色变浅;不同果袋处理的梨果实平均单果质量略降低,果形指数和可溶性固形物含量无显著差异,可滴定酸含量降低;不同类型果袋相比,无纺布袋、外黄内白蜡纸袋果实仍保持绿色,果实品质下降程度最小,果点大小显著降低,果点凸值降低程度小;外黄内黑和外黄内红果袋处理的果实浅黄色,果实外观品质降低程度大。

To explore the effects of six types of bag on the fruit dots of Zhongli No.1 pear,with no bagging as control,the fruit weight,soluble solid,sugar and acid,and fruit shape indexes of pear fruit bagged with different bags at maturity were measured.The fruit dot size,density,height,and area under different bagging treatments were observed and measured.The results showed that the height of the fruit dots decreased significantly and the color of the fruit spot became lighter after bagging.The single fruit weight and the titratable acid content of bagged fruits decreased slightly.There was no significant difference in fruit shape index and soluble solids content among different bagging treatments.The surface of fruits bagged with non-woven cloth bag and yellow outside and white inside wax bag remained green,with the least decrease in fruit quality,and significantly decreased fruit dot size and small decrease of fruit dot height.The fruit surface of fruits bagged with the yellow outer and black inner bag,and yellow outer and red inner fruit bag was light yellow,and the appearance quality was greatly decreased.
