Abstract

This study was carried out to determine the different effect of scion types on bench grafting. Rootstock 110R and Hafizali and Cardinal cvs. were used as a plant material. Scion types performed burst cutting-burst scion, burst cutting-swollen scion, and burst cutting-unburst scion. 21 days after grafting, all grafted cuttings were measured and recorded. The results indicate that discarded grafted-cuttings ratio (%) was found totally to be 3%. In bud, burst values swollen and unburst scions were in same statistical group (53.72 and 52.92%). Best results of shoot length ratio from burst scion in group 0-5 cm (38.62%) and group 5-10cm (4.00%)was found. Rotting in bottom of cuttings was found to be between 4.67 (burst scion) to 11.44% (unburst scion). Rooting ratio were increased along with development of bud; 1.42, 3.44 and 4.67%, respectively for unburst, swollen and burst scions. Highest total callus fresh weight was obtained from swollen scion (1159.35 mg).
