- ABSTRACT Plant resistance to drought had relationship with root length. The root branching and weight could be increased by the root pruning. The research intends to study the effect of roots and leaves pruning on drought resistance of young tea plant. The research was done in Pagilaran tea plantation, Batang district from March to October 2004. This experiment was arranged in the RCBD (Randomized Complete Block Design) factorial 3 x 4, consisted of 2 factors and 3 replications. The first factor was root pruning consisted of control /without pruning (Ak), root prunned 25% of polybag length (A25), and root prunned 50% (A50). The second factor was leaves prunned 25% (D25), pruning consisted of control/ without pruning (Dk), leaves prunned 50% (D50) and 75% (D75) their lenght. Roots and leaves pruning were done on 5 months old of tea seedling. Result of the experiment showed that: no interaction between roots and leaves pruning of tea seedling on all of observed data. Roots pruning of 25% and 50% polybag length repaired the growth of root and lengthened the time length to achieve permanent wilting condition, a character of drought resistant plant. The leaves pruning 25% increased the growth of plant but the leaves pruning more than 50% of their length inhibited the growth of plant. Key words : Pruning, root, leaf, drought, tea.
