The experiment was conducted to characterize the fruit morphological parameters and to study the effect of different pre-sowing treatment on seeds of wild edible fruit tree Phoebe cooperiana U.N Kanjilal ex A. Das. of Arunachal Pradesh. Fruit and seed morphological parameters were based on 100 fruits collected from Lower Dibang district of Arunachal Pradesh. Eight pre-sowing treatments in three replications were given to the seeds before sowing at Department of Tree Improvement nursery, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh. The average fruit weight for the 100 fruits was recorded to be 9.64 ± 1.90g; fruit length 3.62 ± 0.37cm; fruit diameter 2.42 ± 0.59cm; seed weight3.10 ± 0.70g; seed length 2.45 ± 1.01cm; seed diameter 1.35 ± 0.24cm; pulp weight 6.69 ± 1.10g; pulp thickness 1.07 ± 0.10cm and pulp-fruit ratio 0.64 ± 0.21. Significant differences in germination were observed across the treatments. The study revealed that treatment T5 (soaking in 0.05% gibberellic acid for 12 hrs) showed highest germination percentage (51.40 followed by T4 (soaking in 2 % H2O2 12hrs). Although by soaking of seed in water the germination percentage was significantly lower (40.14% and 38.34%) it can be resorted as an economical method of seed treatment for higher seedling production.
