The effects of different applications on rooting and graft success of grafted plant propagation in almond

In this study, the effects of different applications on rooting and graft success of grafted plant propagation in almond were investigated. Hardwood cuttings of GF 677 and Garnem (GN 15) taken at two different times (December and January) were grafted with the almond cultivar named Ferragnes by using whip and tongue grafting method. Subsequently, grafted plants were treated with 0 (control),1000, 2000 ppm IBA, 1600 ppm putrescine, 1600 ppm put + 1000 ppm IBA and 1600 ppm put + 2000 ppm IBA applications, respectively. 60 days from planting, some characters such as graft success ratio (%), rooting ratio (%), callus formation rate (%), number of roots (piece) and root length (mm) were determined separately on grafted plants removed from rooting media. According to the results, the highest rooting (53,3 %) and graft success (96,7 %) ratios were obtained from 1000 ppm IBA application on Garnem, grafted in January. For GF 677, the highest rooting ratio (20 %) and graft success (96,7 %) was observed in 2000 ppm IBA and 1000 ppm IBA applications in January, respectively. It was seen that the rooting ratios, obtained from putrescine and IBA combinations were more less than IBA applications.
