1. the method that after detecting Maize Seedling drought, whether rehydration compensatory growth occurs, is characterized in that, comprises the following steps:

  • Step one, choose growth consistent, emerge after the maize seedling of 6 ~ 12 days, implant in 2n identical Culture basin with every basin m, described 2n basin maize seedling be divided into experimental group a and control group b at random, often organize n basin;

    Step 2, experimental group a carried out to rehydration process after drought, to control group b adequate water supply all the time, ribosylzeatin content in the maize seedling blade of regular sampling detection experiment group a and control group b;

    Step 3, there is drought by the testing result determination Maize Seedling of ribosylzeatin content in the maize seedling blade of comparative test group a and control group b after rehydration compensatory growth whether occur, if the testing result of ribosylzeatin content is significantly less than control group b in maize seedling blade during experimental group a drought stress, after drought, the some skies of rehydration are significantly greater than control group b afterwards, after drought after the rehydration long enough time with control group b without difference, then there is rehydration compensatory growth after drought in Maize Seedling.
