低温胁迫对近无柄雅榕叶片丙二醛和可溶性糖含量的影响

Influence of Low Temperature Stress on MDA and Soluble Sugar Content in Ficus concinna var. subsessilis Leaves

在0、-2、-4、-6、-8℃温度下对近无柄雅榕(Ficus concinna)叶片中MDA、可溶性糖的变化进行研究。结果表明:随着温度的降低叶片中MDA含量呈现先升后降趋势,在0^-4℃条件下逐渐增高,在-4℃时达到最高值,在-4^-8℃条件下逐渐降低;可溶性糖含量随着温度的降低呈现先上升后下降的趋势,从0^-2℃大体呈现上升趋势,-2℃时达到最高值,从-2^-8℃过程中呈现逐渐降低的趋势。

Experiments were conducted on variation of MDA and soluble sugar content in leaves of Ficus concinna var. subsessilis with different temperatures of 0℃,-2℃,-4℃,-6℃ and-8℃. The results showed that MDA content increased from 0℃ to-4℃, and then decreased from-4℃ to-8℃. The contents of soluble sugar increased from 0℃ to-2℃ and decreased from-2℃ to-8℃.
