Position of Leaf TissueThere is considerable variation in the nutrient content of leaves related to their position in the canopy. This variation is influenced by the intensity of exposure to the sun’s radiation and in some instances (e.g. in oil palm for which leaves are selected according to their position on the stem) on the age of the tissue. In order to minimize variation, the type of leaf and/or the position of leaves from mature plants to be selected have been identified for use in Malaysia as follows: Rubber - Basal leaves of top whorl of shoots of branches in shade of canopy, Cocoa- Third or fourth leaf of the last maturing flush, Coffee- Third or fourth pairs of leaves from tips of fruit-bearing branches at midheight of tree, Coconut - Leaf 14, Oil palm - Leaf 17, Mango - Fifth leaf from base of current flush after harvest.
