摘　　要：【目的】研究新选育的柑橘砧木‘蜀砧1号’对‘春见’生长发育及果实品质的影响,为该砧木应用提供理论支撑。【方法】以‘蜀砧1号’‘资阳香橙’和红橘为砧木,‘春见’为接穗,测定3种砧穗组合4 a生树体生长、叶片生理生化、矿质营养和内源激素水平、果实产量和品质。【结果】3种砧穗组合叶片的可溶性糖、可溶性淀粉含量、IAA含量和单株产量以及果实的单果重、纵横径、果形指数和可滴定酸含量无显著差异,春见/蜀砧1号的春梢、夏梢和秋梢长度分别为17.70、22.88和15.18 cm,均高于另外2种砧穗组合的春梢长度。春见/蜀砧1号叶片中N含量(2.49%)、K含量(1.52%)和ZR含量(1.84 ng/g)显著高于另2个砧穗组合,果实可溶性固形物含量为12.24%,显著高于春见/红橘,但与春见/资阳香橙差异不显著。【结论】‘蜀砧1号’适宜作为川渝地区柑橘砧木使用。【Objective】To investigate the effect of the new citrus rootstock'Shuzhen No.1'on the growth and fruit quality of'Harumi',and provide theoretical data support for its application.【Method】The growth,leaf physiological and biochemical characteristics,mineral nutrient contents,endogenous hormone levels,fruit yield,and quality were evaluated in four-year-old trees resulting from three different graft combinations,utilizing'Shuzhen No.1','Ziyang Xiangcheng',and Citrus reticulata as rootstocks,with'Harumi'as the scion.【Result】No significant differences were observed in the levels of soluble sugar,soluble starch and IAA content in leaves,as well as in single plant yield,fruit weight,longitudinal and transverse diameter,and fruit shape index among the three rootstock combinations.In the Harumi/Shuzhen No.1 combination,the length of spring,summer and autumn shoots were 17.70,22.88 and 15.18 cm,respectively,all of which were higher than the other two rootstock combinations in terms of spring shoot length.The content of N(2.49%),K(1.52%),and ZR(1.84 ng/g)in leaves of Harumi/Shuzhen No.1 were significantly higher than the other two combinations.The soluble solids content in the fruit of'Harumi'grafted onto'Shuzhen No.1'was 12.24%,which was significantly higher than that of'Harumi'grafted onto C.reticulata,and the difference was not significant with that of'Harumi'grafted onto'Ziyang Xiangcheng'.【Conclusion】'Shuzhen No.1'is suitable for use as a citrus rootstock in Sichuan and Chongqing areas.
