摘要
The effects of fourteen tying and wrapping materials (soft silicone polyethylene, leathery polyethylene, soft polyethylene, parafilm, cannabis, reed thread, cotton cloth, cotton yarn, plastic yarn, stretch film, electrical tape, plastic sticky tape, paper sticky tape, and teflon tape) and two grafting techniques (chip budding and whip -and-tongue grafting) on graft adhesion, sprouting, shoot length, and shoot diameter were investigated in Japanese flowering crabapple grafting. The budding and grafting were done on April 26, 2015 and 2016. The Japanese flowering crabapple scion was grafted on two-year old Malus floribunda seedling rootstocks in the nursery conditions. Graft adhesion varied from 28.3% to 100.0% in 2015 and from 26.7% to 93.3% in 2016. Sprouting varied from 11.7% to 100.0% in 2015 and from 10.0% to 90.0% in 2016. The highest graft adhesion rate and sprouting rate were obtained from chip budding and whip-and-tongue grafts wrapped with soft silicone polyethylene tape, while the lowest results were obtained from chip budding wrapping with cotton cloth in both years. Graft shoot length varied from 25.1 cm to 69.5 cm in 2015 and from 26.4 cm to 61.7 cm in 2016. Graft shoot diameter varied from 4.0 mm to 6.4 mm in 2015 and from 4.1 mm to 6.0 mm in 2016. The highest shoot length and diameter were obtained from soft silicone polyethylene tape, while the lowest results were recorded from cotton cloth in both years. The best type of tying and wrapping materials were soft silicone polyethylene tape. The lowest results were obtained with cotton cloth. Within non-professional tying and wrapping materials, electrical tape produced better results.
