摘要: Based on the "Qingyu No.1" and "Qingyu No.2 " the two Jerusalem artichoke varieties as experimental materials, the Jerusalem artichoke with different concentration of polyethylene glycol, PEG-6000 stress (0,10%, 20%, 10%) of drought stress on the content of the different parts of the sugar in the treatment of the different time after change were studied; The results showed that: under the stress of PEG, the sugar content in leaf, Qingyu No.1 and Qingyu No.2 all time increases as the stress increases with increasing time; The content in stem, Qingyu No.1 changes in different with stress time increasing, Qingyu No.2 in PEG concentration was 30% and stress 24h the effect is most obvious; the content in root, Qingyu No.1 and Qingyu No.2 with the increase of stress time its content increased.
