Different concentrations of the three varieties of corn Uniconzole was determined in corn germination , seedling quality , the whole growth period of soluble sugar content , soluble protein content , chlorophyll content , leaf area index , specific leaf weight physiological indicators of change , and leaves of maize seedlings under low temperature stress relative conductivity, peroxidase activity, superoxide dismutase activity , malondialdehyde (MDA) content , proline content , test results show that : Uniconzole treatment can significantly inhibit the corn germination potential, but does not affect the germination rate of corn . Uniconazole corn seedlings the strong seedling role , reflected : to inhibit seedling height , stem diameter , promote root growth and increase the number of leaves . In the whole growth period , Uniconazole can significantly improve the soluble sugar , soluble protein content , chlorophyll content increased , increasing the specific leaf weight and delay the late growth stage reduction of the leaf area index . Uniconzole treatment showed increasing effect concentration roughly 30 - 90mg / L is better . By Uniconzole process under low temperature stress , the corn recruits and the damage degree can be significantly lower than the unprocessed plants . Performance : slow down the proliferation of the blade lipid peroxidation product malondialdehyde , proline content increased , and has remained at a high level , reduced cell membrane permeability , and significantly inhibited by cold corn leaf superoxide dismutase (SOD) and peroxidase (POD) activity decline , pushing its ease cold damage mechanism of action , may regulate the metabolism of reactive oxygen species . The uniconazole test three varieties of corn , and the results are obvious performance Uniconazole low concentration of soaking treatment , resilience better than high concentration . The optimal concentration of different varieties .
