钙硼营养对龙眼果实品质及耐贮性的影响

果园土壤低硼条件下,于龙眼假种皮发育期间,树冠分别喷施1?Cl2、0.2%H3BO3、1?-Cl2 0.2%H3BO3溶液及清水3次,探讨Ca、B营养对龙眼果实品质及采后耐贮性的影响。结果表明,0.2%H3BO3、1?Cl2 0.2%H3BO3处理显著提高了果实组织B含量,对增大龙眼果型、提高单果重、增加果实的可食率和果肉糖含量有明显效应,但0.2%H3BO3处理的效果优于1?Cl2 0.2%H3BO3处理,两处理均降低了贮藏期间果实失重率、提高好果率,减缓了果肉营养成分的变化;1?Cl2处理显著提高了果实组织Ca含量,也提高了龙眼果实的耐贮藏性,但对果实品质的影响不明显。

Effects of Calcium and Boron Nutrient on Quality and Storage of Longan Fruit

Effects of Ca and B nutrient on quality and storage of longan fruit were discussed under the condition of lacking of boron nutrient in soil, and spraying three times on leaves and fruits with 1?Cl2, 0.2%H3BO3, 1?Cl2 0.2%H3BO3 solutions and water(CK) respectively during the developmental stage of longan aril. The results showed that both 0.2%H3BO3 and 1?Cl2 0.2%H3BO3 spray had significantly increased B content, shape, weight, edible portion and sugar content in fruits. However, the effect of 0.2%H3BO3 treatment on quality was better than 1?Cl2 0.2%H3BO3 treatment. Moreover, both the two treatments had increased healthy fruit rate, decreased fruit weight lose rate and inhibited changing speed of nutrition of flesh during storage. 1?Cl2 spray had obviously increased content of Ca in fruits, defer postharvest senescence of fruit, but not significantly influenced on quality of longan fruit.
