摘要： 为加快山西省平欧榛抗寒育种的进程，深入挖掘平欧榛抗寒资源，为平欧榛生产育种提供理论依据，以 ‘85-28’、‘达维’、‘薄壳红’、‘B-11’、‘玉坠’、‘84-72’、‘魁香’、‘辽榛3号’等生产中主要的8个平欧榛品种（系）成熟1年生枝条为试材，在自然越冬过程中，对其可溶性蛋白、可溶性糖含量进行测定及差异性分析，并结合露地越冬试验，分析与抗寒性的关系。结果表明，在休眠主要低温期，各品种可溶性蛋白及可溶性糖含量均随温度降低呈递增趋势，且抗寒性强的品种较抗寒性弱的增幅大，平欧榛抗寒性与可溶性蛋白及可溶性糖含量呈正相关性。试验各品种（系）抗寒性强弱顺序依次为‘B-11’、‘达维’、‘85-28’、‘84-72’、‘辽榛3号’、‘玉坠’、‘薄壳红’和‘魁香’，与冻害调查结果相吻合。

Abstract: The paper aims to speed up the cold-tolerance breeding of Corylus heterophylla× Corylus avellana in Shanxi Province, deeply explore Corylus heterophylla× Corylus avellana cold-tolerance resources, provide a theoretical breeding basis for the Corylus heterophylla × Corylus avellanas. 8 main cultivated Corylus heterophylla× Corylus avellana varieties including‘85-28’,‘Davey’,‘Bokehong’,‘B-11’,‘Yuzhui’,‘84-72’, ‘Kuixiang’and‘Liaozhen 3’were used as test materials. Content of soluble protein and sugar of 1 a mature branches of the 8 varieties were tested, and difference analysis was discussed, so as to study relationship between the content of protein, sugar and cold resistance combined with open-field overwintering test. Results showed that during the main low-temperature stage of the dormant period, soluble protein and sugar content of different varieties displayed an increasing tendency, yet varieties with strong cold- resistance had great increasing extent compared with that of varieties with weak cold-resistance, and the content of soluble protein and sugar was positively correlated with cold resistance in Corylus heterophylla× Corylus avellana. The order of cold resistance from strong to weak for the 8 tested varieties was as follows:‘B-11’,‘Davey’,‘85-28’, ‘84-72’,‘Liaozhen 3’,‘Yuzhui’,‘Bokehong’and‘Kuixiang’, which was almost the same as the result of freezing damage investigation of different Corylus heterophylla× Corylus avellana varieties.
