Present investigation was carried out in Department of Horticulture and Agroforestry, CSKHPKV, Palampur, India, during 2018-19. For this, one-year-old seedlings of Citrus jambhiri (Khatti) were grafted with scions of different Citrus spp. viz., C. sinensis (Malta), C. limon (B lemon) and C. aurentifolia (K-lime) on five different nd st nd dates viz., June 2nd week (D1 ), June Last week (D2 ), July 1st week (D3 ), July 2nd week (D4) and July last week (D5 ). Veneer grafting performed during active growth season showed proper callusing and union formations in all graft combinations. However, graft combinations of C. limon and C. sinensis onto C. jambhiri gave best results in terms of grafting success (86.383 and 83.318 %), plant height (27.015 and 28.800 cm), number of leaves and lateral shoots per plant, shoot diameter, root growth and plant biomass production. This method of grafting in citrus proved to be a promising method for multiplication, especially when bark of rootstocks could not be split easily forbudding operations underMid-Himalayan region of HP, India.Downloads
