【摘要】 在龙眼假种皮发育期间,树冠喷施硼营养剂和清水2次,并在果实采收时进行浓度为3g/L、 6g/L的壳聚糖溶液涂膜处理,以探讨硼营养和壳聚糖对龙眼果实品质和耐贮性的影响。结果表明: 采前喷硼改善了龙眼果实的内在品质,提高了果实的耐贮藏性;采后壳聚糖涂膜处理都明显提高了 贮藏期间龙眼果实的好果率、降低失重率,有效减缓了果肉营养成分的变化,其中采前喷硼和采后壳 聚糖涂膜相结合处理的效应优于其它处理,但两个浓度壳聚糖处理产生的效应差异不明显。更多还原

【Abstract】 B nutrient solutions and water (CK) were sprayed on leaves and fruits two times during the developmental stage of aril, effects of boron nutrition and chitosan films on fruit quality and storability of longan were also discussed. The results showed that pre -harvest boron nutrition spray had obviously increased internal quality and storability of longan fruit. Postharvest chitosan films had also significantly increased healthy fruit rate, decreased fruit weight lose rate, inhibited changing speed of nutrition of flesh during storage; The effect of B+chitosan treatment was greater than others treatment, but the effects of 3g/ L and 6g/L chitosan treatment on storability were not significant different.更多还原
