| 摘 要： | 为探讨钙、硼营养对黄冠梨品质和褐斑病的影响，于幼果套袋之前进行叶面喷施0.3% H3BO4 (B)、0.5% CaCl2(Ca)、0.3% H3BO4＋0.5% CaCl2 (B＋Ca) 3次，每次间隔7d的试验。结果表明，3种处理均能显著降低果实贮藏前期果皮多酚氧化酶（PPO）活性、提高过氧化物酶（POD）活性和冷藏期间果皮褐斑指数；其中B+Ca处理效果最明显，并显著提高采收时单果重、果皮中Ca含量、Ca/Mg和Ca/K；Ca、B+Ca处理能降低果皮中可溶性酚含量；B处理显著提高果皮和果肉中的硼含量。这说明B+Ca处理能明显改善黄冠梨果实采收品质和贮藏性能。

| Abstract: | The foliar sprayings of 0.3% H3BO4(B), 0.5% CaCl2(Ca) and 0.3% H3BO4 +0.5% CaCl2(B+ Ca) be-fore the fruit bagging stage for 3 times at 7 day intervals were carried out respectively to study effects of calcium and boron nutrition on quality and browning spot disease of Huanggnan pear. The results show that pelyphenol oxidase(PPO) activi-ty of peel during prophase of storage is significantly decreased in the three treatments (B, Ca and B + Ca), while peroxi-dase(POD) activity is increased, and browning spot of peel is decreased during the cold storage at 0℃. These effects are obvious in the spraying of B + Ca; and fruit weight per fruit, Ca content, Ca/Mg and Ca/K of peel at harvest are signifi-cantly increased in the spraying of B + Ca. Soluble phenol content is reduced in the Ca and B + Ca treatments, and B contents of fruit peel and flesh are significantly increased in the spraying of B. Therefore, quality and storability of Huanggnan pear are significantly improved for spraying of B + Ca. |
