| 摘要: |
| 为评估不同甘蔗(Saccharum officinarum L.)品种在低温胁迫条件下的耐冷性能，并综合考量多个生理生化指标对低温胁迫的响应，本研究选用10个不同甘蔗品种，经过低温处理后对其生理生化特征进行测定，并通过主成分分析法进行综合评价。结果表明，在低温胁迫条件下，各品种之间存在显著差异，呈现出多样的生理生化响应。主成分分析成功解释了84.130%的表型变异，并确定其可溶性蛋白(Soluble Protein，SP)含量、超氧化物歧化酶(Superoxide Dismutase，SOD)活性和质膜透性(Plasma Membrane Permeability，PMP)等可作为主要的甘蔗耐冷性评价指标。综合分析的结果显示，在低温胁迫下，中蔗11号表现出的耐冷性最强，而中蔗13号的耐冷性最弱。研究结果可为耐冷品种优选和耐冷性育种提供重要的参考依据，同时深化对甘蔗耐冷生理生化机制的理论认识与实践应用基础。 |

| Abstract: |
| This study aims to evaluate the cold tolerance of different sugarcane varieties under low-temperature stress and comprehensively assess multiple physiological and biochemical indexes via Principal Component Analysis (PCA).Ten sugarcane varieties were selected for the experiment,and their physiological and biochemical characteristics were measured after low-temperature treatment.The results demonstrated significant variations among varieties,which exhibited diverse physiological and biochemical responses to low-temperature stress.PCA explained 84.130% of the phenotypic variation,identifying key physiological and biochemical indexes,including Soluble Protein (SP) content,Superoxide Dismutase (SOD) activity,and Plasma Membrane Permeability (PMP).Comprehensive analysis revealed that Zhongzhe 11 showed the strongest cold tolerance,while Zhongzhe 13 exhibited relatively weak cold tolerance under low-temperature stress.These findings provide important references for the screening and breeding of cold-tolerant varieties and deepen the theoretical understanding and practical application foundation of the physiological and biochemical mechanisms underlying the cold tolerance of sugarcane. |
