The effect of tying and wrapping materials and their color on budding success in kiwifruit.

摘要

Field experiments were conducted in Turkey, in 2002 and 2003, to study the effect of tying and wrapping materials and their colour on budding success in kiwifruit cv. Hayward. Three-year-old, gallon-container-grown Hayward seedlings were chip-budded with Hayward chip-bud sticks in the first quarter of May. Raffia (black), cannabis fibre, leathery polyethylene band (white), soft rubbery polyethylene tape (white), paper tape, cotton yarn and plastic string (white) were used as tying and wrapping materials in the first experiment. Green, red, black and white raffia were used as wrapping materials in the second experiment. In the first trial, the soft rubbery plastic tape gave the highest graft-take (100%), sprouting rate (96.67 and 100%, for 2002 and 2003, respectively), graft shoot diameter (7.58 mm and 7.62 mm, for 2002 and 2003, respectively) and length (70.43 cm and 78.01 cm, for 2002 and 2003, respectively). Paper tape gave the lowest results. In the second trial, white raffia gave the best results on graft success (96.67 and 93.33%, for 2002 and 2003, respectively) and graft shoot length and diameter. The soft rubbery plastic tape could be effectively used for tying the kiwifruit bud-grafts and white wrapping material increased bud success. The conventional wraps such as cannabis fibre, plastic string, cotton yarn or paper tape were not suitable for kiwifruit budding..
