<![CDATA[This study aims to determine the effect of rootstock age and shade on early grafting growth of durian (Durio zibethinus L.). The environmental design used in this study was using a Split Plot with the main plot being the effect of shading and the subplot being the age of the rootstock which was replicated 3 times. The treatment design consisted of a main plot and subplots. The main plot is the effect of shading (N) with 3 different light intensity levels : N1: 40% light intensity N2: 60% light intensity N3: 80% light intensity. Subplots were the effect of rootstock age (U) which consisted of 3 levels, namely: U1: Age of rootstock 2 weeks. U2 : Age of rootstock 4 weeks. U3 : Age of rootstock 6 weeks. The results showed that the 4-week rootstock age treatment had the best effect on the parameters of the number of open leaves, leaf greenness index; increase in scion diameter at 1-8 (week after grafting/WAG), and increase in rootstock diameter at 8 MSP; Shading treatment of 60% had the best effect on the parameters of shoot rupture age, number of open leaves, leaf greenness index, shoot length increase at 4-8 WAG; The best interactions occurred at 60% shade treatment and 6 weeks of rootstock age on the parameters of bud break age and leaf greenness index; Shade treatment 60% and rootstock age 8 weeks on parameters Number of open leaves, and increase in shoot length; Shade treatment of 80% and rootstock age of 8 weeks for the parameters of scion diameter increase; and 40% shading treatment and rootstock age of 6 weeks for the parameter of rootstock diameter increase.]]>
