喷钙对红地球葡萄果实钙、果胶含量和品质的影响

Effects of spraying calcium on contents of calcium and pectin and fruit quality of Red Globe Grape (Vitis vinifera L.)

  • 摘要: 为明确适用于红地球葡萄的补钙钙源、 时期和部位,设计了在葡萄果实发育的不同时期(幼果膨大期和采收前2周)对不同部位(叶片和果实)分别喷施硝酸钙和糖醇钙的田间试验,分析了喷钙后果实钙、 果胶含量和果实品质的变化。结果表明, 外源喷钙显著提高了红地球葡萄叶柄和果实各部位的钙含量。从喷钙时期上看,幼果膨大期喷钙对果实各部位钙含量的提高明显大于采收前2周喷钙;从钙源种类上看,硝酸钙适合叶片喷施,糖醇钙适合果穗喷施;从喷钙部位看,叶片喷糖醇钙对提高果实采收期的叶柄钙含量效果最为明显,喷钙后,在果实各部位中,果皮钙含量增加最多,为对照的6.6~20.3倍。在幼果膨大期和采收前2周两个时期,果穗喷钙对果皮钙含量的影响均明显大于叶片喷钙,叶片喷钙则更有利于果籽中钙含量的提高。幼果膨大期果穗喷糖醇钙处理采收后的果肉钙含量最高,达到3.98 mg/g,DW,是对照的2.84倍。果肉钙含量与果肉原果胶含量、 总果胶含量以及果粒硬度均呈极显著正相关,说明通过喷钙来提高果肉钙含量有助于提高果实的贮运品质。

     

    Abstract: In order to figure out appropriate calcium source, stage, and apparatus of exogenetic calcium supply for Red Globe (Vitis vinifera L.) grape, a field experiment was conducted to investigate the effects of calcium spray on berry calcium content, pectin content, and fruit quality by spraying calcium nitrate or alditol calcium on leaves or clusters during the young berries stage or two weeks before the harvest. The results indicate that all calcium spray treatments enhance the calcium contents of petioles and all organs of berries significantly, and the calcium contents under the calcium spray during the young berries stage are much higher than those under the calcium spray during 2 weeks before the harvest for both calcium sources and both apparatus spray treatments. Alditol calcium is suitable for cluster spray, while calcium nitrate is suitable for foliar spray. The foliar spray of alditol calcium on both stages induces the highest calcium contents in petiole. The calcium contents in peels increase significantly among all organs of berries, at values of 6.6 to 20.3 times of the control. For both calcium sources and both spray stages, the calcium contents in peels under the cluster spray are higher than those under the foliar spray, while the latter is more favoring to seed calcium contents. The calcium contents in flesh under the alditol calcium spray during the young berries stage are the highest among all treatments, at a value of 3.98 mg/g, DW, which is about 2.84 times of the control. High significant positive correlations are found between the flesh calcium content and flesh total pectin content, flesh proto pectin content and berry firmness, which implies that the calcium spray enhances the calcium content of flesh and thus improves the fruit storage quality.
