摘要
以冷藏后的库尔勒香梨健康果和发生顶端腐烂的果实为试材,采用原子吸收分光光度计测定方法,分析比较了健康果与发病果不同部位的Ca、Mg、K含量,以探讨这种病害发生的原因。结果表明:库尔勒香梨果皮、果肉、果心中Ca、Mg、K含量差异显著。患病果果皮和果肉中的Ca含量明显低于健康果,且顶部Mg、K含量低于健康果,但其差别小于Ca含量的差别。因此,库尔勒香梨萼端腐烂可能与果实果皮、果肉组织缺钙,以及顶部果皮缺Mg有关。
The healthy and diseased fruits of Korla fragrant pear after cold storage were used as materials,and the atomic absorption spectrophotometry mehod was applied to compare the different on the contents of Ca,Mg,K with various parts at two kinds fruits,in order to explore the etiology of this disease. The results showed that the contents of Ca,Mg, K were different in various tissues. It was much lower on Ca content of peel and flesh in diseased fruits, and also lower on Mg,K content of upper tissue than that of health ones,but this different on Mg,K content was smaller than that of Ca content. Thus,the top rot could be related to deficiency of Ca in peel and flesh and lower Mg in upper peel in Korla fragrant pear.
