干旱胁迫下5个种源砂地柏抗旱性研究
Drought Resistance of Juniperus sabina from Different Provenances
摘要
Abstract
In order to evaluate the drought resistance of Juniperus sabina with different provenances,the cuttings of 3 year old Juniperus sabina with 5 provenances from Neimeng,Qinghai,Shanxi,Ningxia and Xinjiang were used as experimental materials,and potted water control method was a-dopted.The leaf water content(LWC),chlorophyll(CHL)content,free proline(PRO)content,ma-londialdehyde(MDA)content,soluble sugar content(SS)content,superoxide dismutase(SOD)ac-tivity and peroxidase(POD)activity were measured respectively,and the membership function meth-od was used to evaluate the drought resistance of the leaves.The results showed that the membership function values of the five provenances of Qinghai,Neimeng,Shaanxi,Ningxia and Xinjiang were 0.518,0.396,0.440,0.437 and 0.550,respectively.The membership function value of Xinjiang was 0.550,ranking the first with the strongest drought resistance.The membership function value of Ju-niperus sabina from Inner Mongolia provenance is 0.396,indicating the weakest drought resistance.The drought resistance was in the order of Xinjiang provenance＞Qinghai provenance＞Shaanxi prove-nance＞Ningxia provenance＞Neimeng provenance.关键词
