dc.description.abstractThe effects of different seed germination and nursery techniques for Phoebe goalparensis Hutch (Bonsum) were investigated in this study and was carriedout in the laboratory and research field of Department of Silviculture and Agroforestry, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh in the year 2015-2017. The experiment in laboratory and field condition for seed was carried out in Complete Randomized Design with 8 treatments which were replicated 4 times. The treatments include, T1- Control (with pericarp), T2- Depulped and sowing in field, T3- Depulped and dipping in hydrogen peroxide (H2O2-2%) overnight, T4- Depulped and sun drying for 8 hours (one day), T5- Depulped and soaking in ambient water for 24 hours, T6- depulped and soaking in luke warm water for 24 hours, T7- Depulped, nicking and soaking in ambient waater for 24 hours and T8- Depulped, nicking and overnight soaking in giberellic acid (0.05%). Result show that highest germination percentage in lab (81.5%) and field (70.0%) and germination value inlab (0.87) and field (0.617) was recorded in treatment T8 [Depulped, nicking and overnight soaking in gibberellic acid (0.05%)]. The viability percentage of the seeds based on tetrazolium test was observed to be (84.33%) and this may be correlated with the highest germination percentage recorded in T8. Different nursery techniques on Phoebe goalparensis were analysed and carried out in Randomized Block Designwith 4 replications. The treatments include, T1- control (in transplanting bed), T2- control (under polybag), T3- Undercutting, T4 Undercutting and one time wrenching, T5- Undercutting and wrenching (4times), T6 -Undercutting and wrenching (6times), T7- Base cutting and T8- Hiko Trays (root trainers). Based on the field observations, the outplanting survival percentage was highest in T2 (96.21%)i.e., polybag at par with T7 (95.51%) i.e., base cutting followed by T6 (87.38%) i.e., Undercutting and 6 times wrenching and T5 (80.81%)i.e., Undercutting and 4 time wrenching indicates that polybag treatment cause poor seedling quality and inferior root deformation. In conclusion, tetrazolium test is a reliable method for determining the seed viability in Phoebe goalparensis. The seeds should be treated with nicking & soaking overnight in gibberllic acid (0.05%) before sowing after removal of pericarp for breaking seed dormancy and getting maximum germination. Base cutting (2.5cm) of polybag seedling, undercutting and wrenching is a successful contribution in improving the outplanting survival of plants corresponding with T7, T6 and T5 performing satisfactory outplanting survivalen_US
