喷硼对梨果硼、钙含量及石细胞形成相关酶活性的影响

Effects of foliar application with H3BO3 on contents of boron and calcium and sclereid development related enzymes in pear fruits

  • 摘要: 以黄花梨为试验材料,分别于幼果期、膨大期和成熟期进行叶面喷施硼酸,研究外源硼对梨果实硼和钙含量、石细胞含量及相关酶活性的影响。结果表明:1)从叶面喷硼对果实吸收硼的短期效果来看,果实发育的不同时期叶面喷施硼酸均促进果实对硼的吸收,其各处理的促进效果顺序为幼果期果实膨大期果实成熟期,不同时期叶面喷施硼酸均提高了果肉中水溶态硼、半束缚态硼和束缚态硼的含量; 2)幼果期喷硼提高了梨果实的钙含量,而果实膨大期和成熟期喷硼降低了果实内的钙含量,但各时期喷硼处理均提高梨果肉细胞壁内的钙含量; 3)不同时期叶面喷施硼酸降低了梨果石细胞含量,果实过氧化物酶、多酚氧化酶和苯丙氨酸解氨酶活性也低于对照,且幼果期处理效果最佳。

     

    Abstract: An experiment was performed to investigate the changes of contents of boron and calcium, and sclereid related enzymes in Huanghua(Pyrus pyrifolia Nakai cv.)pear fruits treated with foliar application with H3BO3. The results show that the foliar H3BO3 application at different developmental stages could increase the contents of soluble, semi-bound and bound boron in fruits, and at which the young fruit stage shows the best effect, followed by the swelling and ripening stages. In contrast with the application at young fruit stage, treatments at swelling and ripening stages could decrease the calcium content of pear fruits, however, the contents of calcium in cell wall are increased whenever the applications are performed. The contents of sclereid and activities of some enzymes, such as POD, PPO and PAL are decreased under the applications of H3BO3, and the effect of the application at young fruit stage is the best.
