中文摘要	【目的】研究干旱胁迫、盐胁迫以及盐旱复合胁迫下的棉花多项生理指标,鉴定棉花品种(系)的抗旱及耐盐水平。【方法】以8份陆地棉品种为材料,室内利用1 /2Hogland营养液水培幼苗至4 ~ 5片真叶时设置对照、11%PEG - 6000、1.2%NaCl及11%PEG - 6000和1.2%NaCl复合胁迫4种处理48 h后,研究不同处理下棉花净光合速率(Pn) 、气孔导度(Gs) 、蒸腾速率(Tr) 、细胞间隙CO_2浓度(Ci) 、水分利用效率(WUE) 、相对含水量(RWC) 、抗坏血酸过氧化物酶(APX) 、叶绿素a(CHla) 、叶绿素b(CHlb) 、总叶绿素CHl(a + b)等10项生理指标,采用抗旱(耐盐)指数PI、综合抗旱(耐盐)指数RI、主成分分析(PCA) 、聚类分析及植物形态评价法相结合对其抗旱性、耐盐性及综合抗逆性进行评价。【结果】8份材料的光合特性及生理指标存在一定差异。基于旱胁迫、盐胁迫及复合胁迫下的10项指标,主成分分析、综合抗旱(耐盐)指数RI值、植物形态评价分析显示,各胁迫下几种方法评价结果基本一致。复合胁迫下的主成分分析分析结果表明,8份材料综合抗逆水平排序如下:新陆中36号> Y1169 > 10615 - 3 > ND359 - 5 > CQJ - 5 > KK1543 >新炮1号>新陆早26号。【结论】通过主成分分析和植物形态评价分析,对8份棉花材料抗旱、耐盐水平进行了分类与评价,为干旱盐碱化地区的品种选育提供了途径。
英文摘要	【Objective】The physiological indices of cotton under drought,salt,drought and salt combined stress were studied in order to select species with the drought and salt resistance.【Method】Control check,11%PEG - 6000,1.2% NaCl,11% PEG - 6000 and 1.2% NaCl combined treatment were set and dealt with 48 hours after 8 upland cotton species were nourished by the hydroponic nutrient of 1 /2 Hogland till the seedlings turned into 4 to 5 leaves. The comprehensive of salt,drought and combined resistance of net photosynthetic rate,stomatal conductance,transpiration rate,intercelluar CO_2 concentration,WUE,RWC,APX activity,CHl a,CHl b and CHl(a + b) content were evaluated by principal components analysis,cluster analysis, the comprehensive assessment as well as plant morphology evaluation method,and its drought resistance, salt tolerance and comprehensive resistance were evaluated.【Result】There existed certain differences in both photosynthetic characteristics and physiological index of varieties under the different treatments. Based on drought stress,salt stress and compound stress,the principal components analysis of the 10 indexes,the comprehensive drought resistance(salt tolerance) index RI value,plant morphological evaluation analysis,the evaluation results were basically consistent under different stress conditions. The results of principal component analysis showed that the comprehensive anti reverse level of 8 materials is as follows: Xinluzhong 36 > Y1169 > 10615 - 3 > ND359 - 5 > CQJ - 5 > KK1543 > Xinluzao 26.【Conclusion】By means of principal component analysis and plant morphological evaluation,the classification and evaluation of drought resistance and salt tolerance of 8 cotton materials were carried out,which provided a practical way for the selection and breeding of varieties in arid saline alkali area.
