Abstract

The study was conducted during the growing season of 2015, at Tawella, locating on 100 km south east of Sulaimani city, Kurdistan Region- Iraq. The aim of this study to determine the best date of budding between two date of budding (June5 and June20) and the best concentration kinetin between three concentration of kinetins (0, 5 and 10) mg/l. The results showes that June20 recorded the maximum value for budding success percentage (73.33%), bud shoots length(64.24cm), bud shoots diameter (0.98cm) and number of leaves (21.05). But higher value of number of branches (1.53) and leaf area (30.68cm2) recorded on June 5. On the other hand 5mg/l of kinetin recorded the maximum value for bud shoots length (72.71cm), bud shoots diameter (1.05cm), number of leaves (22.28) and number of branches (1.65).Whereas, 10mg/l of kinetin recorded the maximum value for budding success percentage (85%) and leaf area(30.75cm2). Interaction of June20 and 5mg/l of kinetin gave (90%) of budding success percentage. But, June5 and 5mg/l of kinetin recorded the maximum value (73.75cm) for bud shoot length, (1.88) for number of branches and (31.91cm2) for leaf area. However, June20 and (0 mg/l) gave the maximum value for both the bud shoots diameter and number of branches (1.18cm and 24.20) respectively.
