不同套袋时间对甜瓜果实外观及品质的影响OACSTPCD
Effects of different bagging time on the appearance and quality of melon fruit
以甜瓜18X-9和W4-3为试材,研究授粉后10 d和授粉后20 d两个套袋时间对甜瓜果实基础性状、质构特性和营养品质的影响,初步筛选甜瓜套袋的适宜时间,明确套袋对甜瓜果实外观和内在品质的影响.结果表明:套袋处理对2个甜瓜材料的果形指数影响不显著,授粉后10 d套袋处理的18X-9果肉厚度、可溶性固形物含量和单果重均高于对照,而授粉后20 d套袋的18X-9果肉厚度、可溶性固形物含量和单果重均显著低于对照.授粉后10 d套袋的W4-3果肉厚度和可溶性固形物含量显著高于其他2个处理,授粉后20 d套袋处理的W4-3除单果重外,果肉厚度和可溶性固形物含量均高于对照.套袋可以显著降低甜瓜的果肉硬度,对果皮硬度的影响较小;果实脆性显著增加,且授粉后10 d套袋效果最佳.授粉后10 d套袋处理的18X-9各品质指标均显著提高,其中,蔗糖和类黄酮含量增加最为显著;授粉后20 d套袋处理的18X-9除果糖和总酚外,其他品质指标值均高于对照.W4-3的2个套袋处理的果实品质均好于对照,其中授粉后10 d套袋对W4-3甜瓜果实品质提升的效果显著好于授粉后20 d套袋.可见,套袋处理对W4-3品质的促进作用好于18X-9,授粉后10 d套袋的效果最佳.
Using melon 18X-9 and W4-3 as test materials,the effects of two bagging time,10 days and 20 days after pollination,on the basic traits,texture characteristics,and nutritional quality of melon fruit were studied to preliminarily screen the appropriate bagging time for melon and clarify the effects of bagging on the appearance and internal quality of melon fruit.The results showed that bagging treatment had no significant effect on the fruit shape index of the two melon materials.The flesh thickness,soluble solids content,and single fruit weight of 18X-9 bagged 10 days after pollination were higher than those of control,while the flesh thickness,soluble solids content,and single fruit weight of 18X-9 bagged 20 days after pollination were significantly lower than those of control.The flesh thickness and soluble solids content of W4-3 bagged 10 days after pollination were significantly higher than those of the other two treatments.The flesh thickness and soluble solids content of W4-3 bagged 20 days after pollination were slightly higher than those of the control,except for single fruit weight.Bagging could significantly reduce the flesh hardness of melon,but had a relatively small impact on the skin hardness;The brittleness of the fruit significantly increased,and bagging 10 days after pollination had a better effect.The quality index of 18X-9 bagged 10 days after pollination were significantly improved,with sucrose content and flavonoids content increasing the most significantly;18X-9 bagged 20 days after pollination showed higher quality index than the control except for fructose content and total phenols content.The fruit quality of the two bagging treatments of W4-3 was better than that of control,and bagging 10 days after pollination significantly improved the fruit quality of W4-3 melon compared to bagging 20 days after pollination.It could be seen that bagging treatment had a better promoting effect on the quality of W4-3 than 18X-9,and bagging 10 days after pollination had a better effect.
