葡萄成熟时随浆果内含钙物质的减少,耐贮性能大大降低,品质也明显下降.为提高葡萄的商品性能和耐贮性能,通过采收前喷钙能有效地克服不利因素,延缓浆果内果胶酸向糖的代谢过程,使葡萄的耐贮期延长,果实的抗压性能及货架寿命期明显提高,浆果在贮存期的褐变速度大大减缓,从而提高了葡萄的商品价值. With the decrease of calcium content in berry fruits, the storability and the storage quality of grapes decrease significantly as the grapes mature.To improve the commercial performance and storability of the grapes, pre-harvest spraying can effectively overcome unfavorable factors, The pectic acid to sugar metabolism process, so that the shelf life of the grape is prolonged, the compressive properties of the fruit and shelf life significantly increased, the berry in the storage period of browning greatly slowed down, thereby increasing the grape’s commercial value.
