摘  要：
以猴樟、香樟当年生幼苗为材料,研究10月至次年3月自然温度变化对猴樟和香樟幼叶中丙二醛(MDA)、超氧化物歧化酶(SOD)和脂肪酸含量的影响。结果表明,在自然降温过程中,2种樟树叶片中的MDA含量呈现先升高后降低的单峰曲线变化趋势,SOD呈现升-降-升-降的双峰曲线;脂肪酸组成成分主要有肉豆蔻酸、棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸;IUFA值(脂肪酸不饱和指数)变化趋势与亚麻酸含量及不饱和脂肪酸含量变化趋势相同,均呈先上升后下降趋势。其中猴樟的MDA含量、SOD活性及IUFA值高于香樟,综合各项指标,猴樟幼苗的抗寒性略强于香樟。

摘  要：
Taking the seedling of Cinnamomum bodinieri and Cinnamomum camphora as material,a study was carried out on the effect of SOD,MDA and fatty acid in their leaves with the changes of natural temperature during October to March.The result indicated that: with the changes in temperature and season,the content of MDA in the two camphor tree leaves shows a single peak curve trend first and then decreased.SOD shows a up-down-up down bimodal curve.The majority of fatty acid compositions were myristic acid,palmitic acid,static acid,oleic acid,linoleic acid,linolenic acid.IUFA value showing a trend of increased and then decreased.The linolenic acid value and the unsaturated fatty acid value take the same trend as the IUFA.Compare the test indicators in the comprehensive analysis of the experimental,the cold resistance of Cinnamomum bodinieri seedlings is slightly stronger than Cinnamomum camphora seedlings.
