Abstract
An experiment was conducted at the Division of forest biology and tree
improvement (FBT), Faculty of Forestry, SKUAST-K. Flowering shoots (Scions) of
five Populus species (P. deltoides, P. ciliata, P. alba,
P. balsamifera and P. nigra) were cleft grafted on rootstock of Populus
deltoides. Days to shoot emergence, percentage of grafting success, number
of sprouted buds per cutting, number of branches, and percentage of graft
survival were recorded for each species. P. alba buds started bursting
after 16.66 days of grafting followed by P. ciliata (14.66 days), P.
balsamifera (13.00 days), P. deltoides (12.66 days) and P. nigra
(11.66 days). P. deltoides (94.00%) showed highest grafting success
while as P. alba (70.00%) showed lowest grafting success. Number of
sprouted buds per cutting were highest in case of P. deltoides (5.24)
while as lowest were in case of P. alba (2.32). Number of branches were
highest in case of P. deltoides (3.92), and lowest in case of P. alba
(2.04). The highest percentage of grafting survival was recorded for P.
Deltoides (88.00 %) followed by P. ciliata (80.00 %), P. alba
(68.00 %), P. nigra (56 .00%) and P. balsamifera (52.00 %). In
nutshell it can be concluded that the homoplastic grafting between P.
deltoides on the rootstock of P. deltoides showed better grafting
success and survival as compared to heteroplastic grafting.
