| 摘 要： | 通过测定核桃枝条的总酚和黄酮类化合物的含量、酚酸的种类及含量,结合其抗性表现,分析核桃枝条酚类物质含量与其抗性的关系。结果表明:供试5个核桃品种中,总酚含量存在极显著差异,以中林1号为最高,晋龙1号最低。中林1号和晋龙1号的黄酮类化合物含量极显著高于京861和薄壳香,礼品2号居中。共检出7种酚酸,即没食子酸、对羟基苯甲酸、香草酸、咖啡酸、丁香酸、对香豆酸和阿魏酸,其中没食子酸含量(约占酚酸总量的70%)高于其余6种酚酸,对羟基苯甲酸、香草酸和咖啡酸在部分品种中未检出。抗寒和抗抽条能力强但抗病性中等的中林1号总酚含量(45.46 mg/g)与其余4个品种存在极显著差异,没食子酸含量(4.50 mg/g)和酚酸总量(5.14 mg/g)均为最高;并检出了其余4个品种中均未检出的香草酸和很少检出的咖啡酸,未检出其余4个品种中均检出的对羟基苯甲酸,丁香酸(0.084 mg/g)和对香豆酸(0.065 mg/g)的含量明显低于其余4个品种。而抗病性强的薄壳香丁香酸(0.371 mg/g)和对香豆酸(0.296 mg/g)的含量则相对较高。

| Abstract: | Considering walnut's resistance performance,the total phenolic content,flavonoids content,phenolic acids types and content in walnut branches were determined to study the relationship between phenolic content and its resistance.There are significant(P≤0.01) difference among different walnut cultivars in total phenolic contents.Of all the five cultivars tested,Zhonglin No.1 is the highest and Jinlong No.1 is the lowest.The flavonoids content of Zhonglin No.1 and Jinglong No.1 are significant(P≤0.01) higher than that of Jing861 and Bokexiang,and Lipin No.2 middle.Seven phenolic acids are detected in the five cultivars which were gallic acid,p-hydroxybenzonic acid,vanillic acid,caffeic acid,syringic acid,p-coumaric acid and ferulic acid.The content of gallic acid is relative high(accounting for 70% of the sum of the phenolic acids).P-hydroxybenzonic acid,vanillic acid and caffeic acid are not detected in some cultivars.Zhonglin No.1 with strong cold resistance is very different from the other four cultivars in which the total phenolic content(45.46mg/g),gallic content(4.50mg/g) and the sum of phenolic acids content(5.14mg/g) are all the most,and the vanillic acid and caffeic acid are detected which they are not or few in the other four cultivars.The p-hydroxy benzoic acid were not detected which were all detected in the other four cultivars.The syringic acid(0.084mg/g) and p-coumaric acid(0.065mg/g) levels were significantly lower than that in the other four varieties.However,the syringic acid(0.371mg/g) and p-coumaric acid(0.296mg/g) contents were relatively high in Bokexiang which had strong disease resistance. |
