Abstract:

A suitable root conditioning treatment encourages development of fibrous root network which plays an important role in outplanting performance in seedlings. To overcome the problem of root coiling in polybag and possibility of root conditioning in Phoebe goalparensis. Hutch seedlings, the experiment consists of base-cutting, root-trainer, different combinations of undercutting and wrenching along with control (untreated seedling in raised bed and polybag) was investigated for their out planting success at Experimental Farm of College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh. Results one year after outplanting for survival were 96.21 % in control (i.e. seedling under polybag with root coiling deformation), and 95.51 % in base-cutting polybag at 1.5 cm from bottom (which need transportation care during outplanting). Owing to get the improved outplanting survival and minimum transportation cost, the bare-rooted seedlings with undercutting depth of 18 cm in July and six times wrenching from month of September to June exhibited 87.38% survival, followed by undercutting depth of 18 cm in July and four times wrenching from month of September to April was 80.18% survival. The results revealed that the undercutting and wrenching treatments were considered appropriate for better performance of seedlings to withstand outplanting stress. The seedling which was not subjected to any undercutting and wrenching treatments (bare root control in raised bed) had lowest outplanting survival (49.94%).
