3个品种油茶对低温的生理响应OACSTPCD
Physiological Effects of Low Temperature on 3 Camellia Varieties
针对油茶受低温的影响,在信阳地区不能大量种植的问题,以安徽油茶、江西油茶、福建油茶等3个品种油茶为试验材料,研究了低温对3个品种油茶幼苗叶光合和生理指标的影响.结果显示:幼苗最大光化学效率(Fv/Fm)下降,相对电导率上升,超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)抗氧化酶类的酶活性升高,丙二醛、可溶性糖、脯胺酸含量上升.3个品种油茶幼苗中,安徽品种具有更好的低温适应性.
In view of the problem that Camellia oleifera was affected by low temperature and cannot be planted in large quantities in Xinyang area,the influence of low temperature on the leaf photosynthesis and physiological indexes of Anhui,Jiangxi and Fujian Camellia oleifera seedlings were studied as test materials.The results showed that the maximum photochemical efficiency(Fv/Fm)decreased;the relative conductivity increased;the enzyme activity of superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)antioxidant enzymes increased;the content of malondialdehyde,soluble sugar and proline acid increased.Anhui varieties in three varieties showed better low temperature adaptability.
