The profiles and tensile strength on straight roots of plants withstand transient tensile injured after self-repair

Abstract Plants roots are severely injured during the process of withstanding transient tensile, and the injured roots can self-repair. We investigated the change law of the growth characteristics and tensile strength on straight roots withstand transient tensile injured after self-repair. The survi...
