基于不同方法对长白山食用玫瑰的抗寒性评价
Evaluation of Different Methods for Cold Resistance of Edible Roses in Changbai Mountain
摘要
Abstract
Three methods were used to evaluate the cold hardiness of Changbaishan edible roses,namely,overwintering suitability class evaluation,recovery growth test after low temperature stress,and cold overwintering assay.The results of statistical analysis showed that the overwintering suitability class evaluation showed that the cold hardiness index of Changbaishan edible roses was 0.27 and they could be planted in the open field with normal growth and development in Tonghua,Jilin.In the low-temperature stress recovery growth test,the bran-ch sprouting rate of Changbaishan edible rose ranged from 60％to 98％,which was the best performance in comparison with the other three rose varieties.The effect of the cold-proof overwintering assay showed that the cold-proof treatment did not have a significant effect on the growth of each of the new branches of Changbaishan edible roses the following year.Therefore,the test results obtained by the three methods matched.关键词
