Effect of Budding Date and Benzyl Adenine on Budding Success Ratio of Clementine Mandarin

Abstract

This study was conducted at the department of Horticulture College of Agriculture, University of Baghdad for the period 1/ 9/ 2002 to 15/ 1/ 2004. To study the effect of budding date and Benzyl adenine on bud take on Clemntine mandarin, using one year old sour orange seedling as a rootstock.

The interaction between date of budding and the treatments significantly influenced the percentage of budding success and improving the vegetative characters.
