摘　　要：为了筛选适合鱼菜共生栽培系统的耐热生菜品种,利用主成分分析法对11个高温条件下处理的生菜品种(含对照)的形态指标和生理指标进行了比较。结果表明:高温条件下不同生菜品种的形态指标和生理指标均显著高于对照,其中生菜品种‘辛普森’和‘罗马直立生菜’表现较好。利用主成分分析法将10个耐热指标通过降维处理转化成2个互不干扰的主成分综合指标,累计贡献率为93.11%。基于耐热性综合评价将11个生菜品种聚成3类:不耐热品种、中等耐热品种和耐热品种。其中,耐热生菜品种为‘罗马直立生菜’‘辛普森’‘美国大速生’。该聚类结果与供试生菜品种的耐热指纹图谱聚类结果基本吻合,说明该评价体系可以很好地反映参试生菜品种的综合耐热能力。In order to screen heat-resistant lettuce varieties suitable for aquaponics cultivation system,the morphological and physiological indexes of 11 lettuce varieties(including control) treated under high temperature were compared by principal component analysis. The results showed that the morphological and physiological indexes of different lettuce varieties were significantly higher than those of the control under high temperature conditions,and lettuce varieties ‘Simpson’ and ‘Romaine lettuce’ performed better. The principal component analysis method was used to transform 10 heat-resistant indexes into 2 non-interference principal component comprehensive indexes through dimensionality reduction,with a cumulative contribution rate of 93. 11%. Based on the comprehensive evaluation of heat-resistance,11 varieties of lettuce were grouped into 3 categories:heatsensitive varieties,medium heat-resistant varieties and heat-resistant varieties. Among them,the varieties of heatresistant lettuce were ‘Romaine lettuce’,‘Simpson’ and ‘American fast growing’. The clustering results were basically consistent with those of the heat-resistant fingerprint of the tested lettuce varieties,indicating that the evaluation system could well reflect the comprehensive heat-resistant ability of the tested lettuce varieties.
