Abstract：To select excellent apple rootstock resources,using four rootstocks (SD1,SD2,SD3,SD4)as candidate rootstocks and four apple stocks commonly used in production (Malus hupehensis (Pamp.) Rehd.,Malus robusta Rehd.,Malus 26) as materials,the mechanical characteristics were researched.The compression test and tensile property test were conducted with the accurate micro-controlled electronic universal testing machine,and the torsion test was conducted with the microcomputer control electron torsion testing machine.The results were as follows.The compressive strength parallel to grain of apple rootstocks ranged from 20.36 MPa to 29.40 MPa.The compressive strength of SD1 (29.40 MPa) and SD3 (28.79 MPa) were highly significantly greater than that of Malus hupehensis (26.61 MPa) and Malus 26 (23.01 MPa).The tensile strength parallel to grain of apple rootstocks ranged from 37.53 MPa to 57.37 MPa and that of SD1 (56.63 MPa),SD2 (57.37 MPa) were all significantly or very significantly greater than that of Malus prunifolia var.ringo (37.53 MPa) and Malus 26 (47.73 MPa).The torsional strength of apple rootstocks ranged from 22.04 MPa to 30.43 MPa,and that of SD2 (30.43 MPa) was highly significantly greater than that of other apple rootstocks,while SD3 (25.68 MPa),SD1 (24.90 MPa) and SD4 (24.54 MPa) had no significant differences with Malus hupehensis (25.53 MPa) and Malus 26 (24.33 MPa).In conclusion,the basic mechanics indexes of candidate rootstocks were not inferior to common apple rootstocks in production,and satisfied the requests in production.
