2012～2013年研究采后浸钙处理对库尔勒香梨果实Ca、Mg、K含量及萼端黑斑病发生的影响。结果表明,浸钙处理提高了香梨果皮和果肉中的Ca、Mg含量和Ca/Mg,其中6%CaCl2处理对提高Ca含量的效果更显著,同时,浸钙处理降低了K含量和K/Ca,其中6%CaCl2处理对降低K/Ca的效果更显著。浸钙处理,能够明显降低萼端黑斑病的发生,在3个处理中,以4%CaCl2溶液处理对防治萼端黑斑病的效果最好,发病率为0,6%CaCl2和8%CaCl2溶液处理的发病率比对照分别降低74.4%和79.3%。
Effects of Postharvest CaCl 2 Treatment on Contents of Ca, Mg, K and Occurrence of Black Spot on Calyx in Korla ’s Pear from 2012 to 2013. The results showed that calcium treatment increased the content of Ca, Mg and Ca / Mg in pear peel and pulp, and 6% CaCl2 treatment had more significant effect on increasing Ca content. Meanwhile, the calcium treatment reduced K content and K / Ca, of which 6% CaCl2 treatment to reduce K / Ca more significant effect. CaCl2 treatment could significantly reduce the occurrence of black spot on the calyx side. Among the three treatments, the treatment with 4% CaCl2 solution had the best effect on the control of calyx terminal black spot disease with the incidence of 0,6% CaCl2 and 8% The incidence of CaCl2 solution treatment decreased by 74.4% and 79.3% respectively compared with the control.
