Abstract
Hevea brasiliensis is an important tree that serves as the Natural Rubber source for commercial utilisation. The exploitation of latex from Hevea is by controlled wounding of the bark of the plant called tapping. The bark tissue system, which is formed as secondary phloem during the secondary growth of the plant, is the central tissue system that contains latex-containing latex vessels. Therefore, anatomically the bark characters have a pivotal physiological role in the latex production in the latex vessels and thereby its commercial exploitation. The present investigation aims to understand the interrelationship of various anatomical factors in nine prominent clones of Hevea. Statistical analysis proved that characters including laticifer area index, the girth of the plant, total bark thickness, inner hard bark thickness, stone cell area in inner hard bark, sieve tube diameter, total latex vessels density, number of stone cell rows in inner hard bark have significant interrelation. The most significant outcome of this study is that these statistical inferences can be used to find out the selection of clones in Hevea.
