Abstract:
Studies were conducted on vegetative propagation of jack. Grafting, budding
and layering were tried. Approach grafting was found successful. All other
methods of grafting, budding and layering on bearing tree gave negative results.
Layering on one year old seedlings gave very good results. Best results were
obtained with ring layering done within 10 cm from bottom of the plant with coconut
pith as the media. Since juvenile factor is supposed to play an important role
in rooting, it may be possible to propagate jack vegetatively by inducing new shoots
near the collar region of the selected mother plants and then undertaking layering on
these new shoots.
