摘　　要：为筛选‘云柠1号’柠檬养分高效利用型砧木,于柠檬第1次生理落果期、第2次生理落果期、果实膨大期和果实成熟期分别测定不同砧穗组合柠檬叶片和果实9种矿质元素含量,并在果实成熟后测定果实品质。结果表明,C35和枳壳2种砧木下,‘云柠1号’叶片的N和Zn以及果实的N、P、Mg、Mn、Zn、Cu元素均在生理落果期含量最高,随着果实膨大和成熟其含量逐渐减少。枳壳砧木处理柠檬果实纵径和可滴定酸含量显著高于C35砧木,果实其他指标没有显著差异。结合大、中、微量元素高效吸收利用特性和果实品质,可考虑以枳壳作为‘云柠1号’的砧木,以达到柠檬对矿质元素养分的高效吸收。In order to select‘Yunning No.1’ rootstock for efficient nutrient utilization,this study measured the content of nine mineral elements in lemon leaves and fruits of different rootstock combinations at the first physiological fruit drop,the second physiological fruit drop,the fruit expansion and fruit ripening stages,respectively.Fruit quality was measured after fruit ripening to compare the differences in mineral nutrient uptake and fruit quality of lemons on different rootstocks.The results showed that with‘Yunning No.1’ as scion,the N and Zn contents of leaves of both rootstocks C35 and trifoliate orange,and the N,P,Mg,Mn,Zn and Cu contents of fruits were the highest in the physiological fruiting stage.And then the contents gradually decreased as the fruits enlarged and matured.In terms of fruit quality indexes,the longitudinal diameter and titratable acid content of trifoliate orange rootstocks were significantly higher than those of C35 rootstocks,and there was no significant difference in other indexes.Combining the characteristics of efficient nutrient uptake and utilization and fruit quality,trifoliate orange could be considered to use as the rootstock of‘Yunning No.1’,to achieve efficient nutrient uptake of mineral elements.
