Abstract
The studies concerns with electronic conductivity, nitrate reductase(NR) activity, solubility protein content, solubility sugar, sucrose content, K +, Mg 2+ and Ca 2+ content of lixivium of plants, plant height, plant dry weight, plant fresh weight and dry matter weight of remain seeds of corn during germination under chilling(3.0℃)condition. Height, dry and fresh weight of seedlings decreased, solubility protein, solubility sugar and sucrose content assume the trend of decrease along with the increase of leaf age and day-age, but relative electronic conductivity, K +, Mg 2+ and Ca 2+ content of lixivium of plants submit the trend of increase. These illuminate accordingly that the chilling resistance of corn seedlings is decreased gradually during the autotrophic period transformed from heterotrophic period, i.e. chilling sensitivity is increased gradually. The difference of apiece index between chilling treated and contract plant are biggest at 15 d (or 17 d) without exception, that account for chilling sensitivity of corn seedlings is biggest at this period as independent of albumen period.
