摘要:
以11种新疆蔷薇属植物为试材，测定不同温度冰冻处理下的相对电导率（REC），运用Logistic方程计算其半致死温度（LT50），并结合第2年自然冻梢程度，对新疆蔷薇属植物的抗寒性进行对比评价。结果表明：刺蔷薇(R.acicularis)的抗寒性最强，异味蔷薇（R.foetida）的抗寒性最弱。第2年的自然冻梢程度与测定的半致死温度（LT50）呈强且为正的直线相关关系，验证了半致死温度（LT50）作为蔷薇属植物抗寒性指标的可靠性。
Abstract:
Taking 11 Rosa species in Xinjiang as test materials，the relative electric conductivity (REC) with different temperature freezing was determined.The logistic equation was constructed based on the relationship between REC and temperature，then the semi-lethal temperature (LT50) was determined.The relation between the extent of frozen tips in the second year and the (LT50) was calculated.The results showed that R.acicularis was defined as the hardiest species and R.hugonis was defined as the most cold sensitive one in the experiment.The relation between the extent of frozen tips in the second year and the LT50 was showed a strong and positive linear correlation,that has proved the (LT50) was a credible indicator to evaluate the cold resistance for Rosa species.
