Abstract

Abstract:

Abstract: In order to explore the effects of dwarfing interstock on pear tree growth, the 23 different interstocks, each of which was combined between Pyrus betulaefolia （as the base stock） and Whangkumbae pear (as the scion), were used as test material. After four years of growth, the indexes of graft union circumference, interstock circumference, length of scion shoot, number of shoot leaves and leaf curl were investigated. Statistical analysis results showed that: BA29, OHF97 and K6 dwarfing interstocks had the best dwarfing effect on Whangkumbae pear. There was a certain correlation between interstock graft-compatibility and rootstock circumference, branch and leaf growth, and the correlation order for the base stock circumference > shoot internode length > ratio of upper graft union circumference to scion circumference (D/E) > ratio of lower graft union circumference to interstock circumference (B/C) > shoot leaf curls > shoots length. The leaf curl was thought to be useful for the early screening of the graft-compatibility, and the ratio of upper graft union circumference to scion circumference (D/E) was more accurate to indicate graft-compatibility.

Key words: pear, graft compatibility, plant height, leaf curl
