This study explores the possibility of using interstock in
vegetative propagation to improve the growth and yield of Hevea
brasiliensis (m.e.l. Arg.).
The parameters investigated were growth and yield of young
and mature trees. Other parameters studied included leaf and
stomatal characters, photosynthetic rate and bark anatomy of
scion with the objective of providing possible explanations for
some of the interstock effect on scion growth and yield.
The various aspects of scion growth affected by inter stock
clones were scion height, girt h and its increment, dry weights
of various plan parts, mean relative growth rate and mean net
assimilation rate, t he distribution of dry matter intovarious
plant parts, leaf area, leaf area ratio, photosynthetic rate,
stomatal frequency and stomatal size
