摘要
测定经过热锻炼的14个高羊茅品种在50℃恒温水浴下处理不同时间的相对电导率值,拟合Sigmoidal曲线计算半致死时间,从而鉴定不同高羊茅品种的耐热性。结果表明,耐热性强的是TF01和TF05;耐热性中等的是(从强到弱排列):TF03、TF13、TF16、TF06、TF07、TF19、TF08和TF14;耐热性较弱的是(从强到弱排列):TF11、TF10、TF18;耐热性最差的是TF12。
The relative electronic conductance rate of 14 tall rescue varieties under 50℃ uater bath for different time was tested. According to the semi-lethal time, which derived from the sigmoidal curve,heat tolerance of the 14 tall rescue varieties were compared. The results showed that TF01 and TF05 had the strongest heat tolerance; then it comes to TF03,TF13,TF16, TF06, TF07,TF19, TF08 and TF14 ; while TF11, TF10 and TF18 were weak in heat tolerance; and TF12 were the weakest.
