摘要:
以佛甲草、胭脂红景天、凹叶景天和中华景天4种景天属植物为试验材料进行人工低温处理（0，-3，-6，-9，-12，-15 ℃）24 h。低温处理后在20 ℃、相对湿度70%的人工气候箱内恢复生长15 d，再对其叶片各项生理指标进行测定。结果表明，恢复生长中，相对电导率由大到小依次是凹叶景天＞佛甲草＞中华景天＞胭脂红景天；叶绿素由大到小依次是中华景天＞胭脂红景天＞凹叶景天＞佛甲草；SOD活性由大到小依次是佛甲草＞凹叶景天＞中华景天＞胭脂红景天；可溶性蛋白含量由大到小依次是佛甲草＞凹叶景天＞胭脂红景天＞中华景天；MDA含量由大到小依次是佛甲草＞凹叶景天＞胭脂红景天＞中华景天；脯氨酸含量由大到小依次是胭脂红景天＞佛甲草＞凹叶景天＞中华景天。根据作者人工低温处理直接测定的结论，进一步论证了4种景天属植物抗寒能力依次为胭脂红景天＞中华景天＞佛甲草＞凹叶景天。
Abstract:
The plants of Sedum lineare,S. spurium ‘Coccineum’,S. emarginatum and S. hispanicum were treated with low temperature (0, -3, -6, -9, -12,-15 ℃) for 24 h, then put in the artificial climate box with 20 ℃ and 70% of relative humidity and then the physiological indexes were tested.The results showed that in the recovery growth process,relative electric conductivity,from higher to lower,was S. emarginatum＞S. lineare＞S. hispanicum＞S. spurium ‘Coccineum’.Total chlorophyll, in order, was S. hispanicum＞S. spurium ‘Coccineum’＞ S. emarginatum＞S. lineare. The order of SOD activities was S. lineare＞S. emarginatum＞S. hispanicum＞S. spurium ‘Coccineum’.Soluble protein content order was S. lineare＞S. emarginatum＞S. spurium‘Coccineum’＞S. hispanicum. As for MDA content, the order was S. lineare＞S. emarginatum＞S. spurium‘Coccineum’＞S. hispanicum. For proline content,the order was S. spurium‘Coccineum’＞S. lineare＞S. emarginatum＞S. hispanicum. The cold resistance of S. spurium ‘Coccineum’ and S. hispanicum were better than that of S. lineareand S. emarginatum. Combined with previous conclusions of low temperature treatment,the cold-resistance ability of them had been further demonstrated, showed in order asS. spurium ‘Coccineum’＞S. hispanicum＞S. lineare＞S. emarginatum.
