摘要: 以马铃薯品种克新1号为实验材料,利用0.5%和1.0%Ca(NO3)2进行采后浸钙处理,分析其对细胞膜的相对透性及过氧化物酶(POD)活性的影响。结果表明:钙处理能有效降低相对电导率和丙二醛(MDA)含量,提高过氧化物酶活性,从而增加马铃薯块茎的耐贮藏性,其中以1.0%Ca(NO3)2处理的效果最好。

Abstract: Take potato variety Kexin 1# as the experimental material, processing the leaching of calcium by 0.5% and 1.0% Ca(NO3)2 after picking, to analysis the effect on the cell relative membrane and POD activity. The results show that: Calcium treatment may reduce the relative conductivity and MDA content effectively, improve the POD activity, thereby to increase the storability of the potato tubers, and founded that the processing by 1.0%Ca(NO3)2 may obtain the best result.
