摘要: 用不同浓度CaCl2溶液对木洞杨梅果实进行采前喷钙处理,研究其对果实品质和延缓衰老的影响,达到延长贮藏期的目的。结果表明:钙处理能有效维持果实的硬度,延缓可滴定酸、可溶性固形物、Vc含量的下降;钙处理能显著降低果实的腐烂率、损失率和呼吸强度;钙处理在一定程度上抑制了果实膜透性和丙二醛(MDA)含量的增加,显著抑制超氧化物歧酶(SOD)活性的降低。从而延缓果实成熟衰老进程,较好的保持了果实品质。3种喷钙浓度处理中以 0.25% CaCl2 溶液效果最好

Abstract: In order to provide basic theory for the optimal storage conditions and methods for Red bayberry Mudong fruits , the influences of calcium treatment(preharvest spraying Calcium) on storabilities of Red bayberry Mudong fruits were studied . Results indicate that the calcium treatments effectively retained the fruit firmness and soluble solid,titratable acid and Vc content ; calcium treatments significantly reduced the rate of fruit loss , rotten fruit rate and fruit respiration ; calcium treatments could inhibit the increase of fruit membrane permeability and MDA content , and remarkably restrain the decrease of SOD activities. Thus the storage quality is inproved and the shelf life Red bayberry Mudong can be prolonged . the effect of 0.25% CaCl2 was the best among the three kinds of calcium concentrations treatments.
