本试验采用 0 .2 %硼酸 ,在胡柚、柑花期进行叶面喷施 ,研究硼对不同柑桔品种果实的钙硼含量、生理病害及耐贮藏性的影响 .结果表明 :硼处理显著提高柑桔幼果期、果实膨大期及成熟期的叶片、果皮、果肉硼含量 .其中 ,硼含量幼果期 >膨大期 >成熟期 ,叶片 >果皮 >果肉 ;硼含量的提高显著影响各部位钙的含量 ,显著降低了叶片及幼果期、膨大期果实的钙硼比值 ;硼处理还显著降低了柑桔生理病果率和贮藏烂果率 ,硼与生理病果率的相关性幼果期 >膨大期 >成熟期 ,果皮 >叶片 >果肉 ,与烂果率的相关性则有随生育进程而增大的趋势 .两品种比较 ,胡柚对低硼条件更为敏感
In this experiment, 0.2% boric acid was applied to foliar spray at the flowering stage of grapefruit and ponkan to study the effects of boron on calcium and boron content, physiological disease and storage of fruits of different citrus varieties.The results showed that boron treatment was significant The contents of boron in leaf, peel and pulp of the young fruit, the peel and the fruit in the young and mature stages of fruit were increased, and the content of boron in young fruit> swelling period> maturity and leaf> peel> Calcium content significantly reduced the ratio of calcium to boron in leaves and young fruit and swollen fruit; Boron treatment also significantly reduced the rate of physiological disease and storage of bad fruit, boron and physiological disease rate of young fruit The correlation between the rate of rotting and peel, fruit peel, leaf> flesh increased with the growing process.The two cultivars were more sensitive to low boron
