摘　　要：【目的】通过联合分析不同砧木砂糖橘植株株高、产量、品质的相关指标,构建砂糖橘优良砧木筛选的综合评价模型,为砂糖橘优良砧木的选择提供依据。【方法】以10种不同的砧木嫁接砂糖橘,对嫁接后的植株株高、产量、品质进行差异显著性分析、相关性分析及主成分分析,获得筛选砂糖橘砧木的核心指标并构建综合评价模型,根据模型评分进行排序。【结果】株高、产量、品质22个指标均表现出了显著的差异性并有着多组相关关系,主成分分析筛选出了6个主成分,累积贡献率达到了93.407%,共注释了包括果实质量及横纵径大小决定因子、产量和果形指数决定因子、果皮厚度决定因子等6个关键因子。【结论】综合评价模型得分表明,红黎檬、香橙和粗柠檬可推荐为广东省适用的3个优选砂糖橘砧木。【Objective】The study aims to establish a comprehensive evaluation for the selection of superior rootstocks for Shatang mandarin by analyzing the plant height,fruit yield and fruit quality of Shatang mandarin on different rootstocks under netted house cultivation.【Methods】Ten different rootstocks were grafted with Shatang mandarin.The difference significance analysis and correlation analysis were carried out on 22 indexes related to plant height,fruit weight per plant and fruit internal and external quality.Finally,the 22 indexes were subject to principal component analysis to obtain the core indexes for the selection of Shatang mandarin rootstocks,and a comprehensive evaluation for rootstocks was thus constructed.【Results】The results showed that there were significant differences in plant height,fruit weight per plant and fruit internal and external quality of Shatang mandarin among the ten citrus rootstocks.The plant height on Sour pummelo was not significantly different from the self-rooted Shatang mandarin.Plant height on Flying dragon trifoliate orange was significantly reduced(50.79%)that on self-rooted plant,showing dwarfing effect of Flying dragon trifoliate orange rootstocks.In the results of soil and plant analyzer development(SPAD)value,it could be seen that Flying dragon trifoliate orange rootstocks with strongest dwarfing effect had the highest SPAD value,reaching 71.92.Selfrooted on Shatang mandarin had the highest plant height,on the contrary,the SPAD value was the lowest,which was 59.44,and the SPAD values of the other rootstocks were also higher than that of Shatang mandarin,which indicated that there was a certain correlation between plant height and SPAD value.Under the unified production management,yield per plant of Shatang mandarin on Goutou sour orange rootstocks was the highest.Different rootstocks had differential effects on 19 indexes related to fruit quality.The single fruit weight and pulp weight in plants on Xiangcheng and Red limonia were higher than those on the other 8 r
