dc.descriptionThe present study was accomplished to know the population of Heritiera macrophylla Wall. inside the Reserve forest in an effort to study further and conservation for the future, effects of seed germination and various nursery techniques. The study was conceded out in 4 Reserve forest in the plain area surrounding Pasighat forest range (Loki, Pikimuk Reserve forest in Pasighat range, Poba Reserve forest in Ruksin range, and Siko Reserve forest in Mebo range) and in the laboratory and field of Department of SAF, CHF, Pasighat, Arunachal Pradesh in the year 2017-2019. On surveying the reserve forest, only one Reserve forest was found to have occurred with the species and the data collected from there gives the frequency, density and abundance of 20%, 0.25 and 1.25 respectively. Among the 14 treatments for germination parameters in the laboratory, condition T13 {seed soaking in gibberellic acid 0.05% (overnight)} gives highest in germination percentage, germination value and peak value with 83.33%, 8.23 and 2.87 respectively. Energy period was fast in T14 {Split open the pericarp on ā€˜Cā€™ with knife followed by gibberellic acid 0.05% soaking (overnight)} with 26 days. Similarly, in field condition, germination percent was highest in T13 {seed soaking in gibberellic acid 0.05% (overnight)} with 86.67% and the rest parameters - germination value, peak value and Energy period were highest in T14 {Split open of the pericarp on ā€˜Cā€™ side with knife, gibberellic acid 0.05% (overnight)} with 9.40, 3.17 and 20 days respectively.en_US

For seedling growth in the polybags, among the 22 treatments, T12 {Soil + Sand + Vermicompost (1:1:1)} gives the tallest plant with (43.00 cm), T9 {Soil + Cocopeat + Vermicompost (1:1:1)} gives the longest root with (26.67 cm), T10 {Soil + Cocopeat + Vermicompost (1:1:1)} gives the highest collar diameter with (9.27 mm), T11 {Soil + Sand + Vermicompost (1:1:1)} gives the maximum number of leaves with (11.67), T9 { Soil + Cocopeat + Vermicompost (1:1:1)} gives the best root-shoot ratio with (0.38) and T18 { Soil + Sand + FYM (1:1:1)} gives the finest in root fibrosity, shoot biomass and total biomass with (264.00 cm2), (9.13 g), (14.60 g) and T15 gives the best root biomass with (5.93 g). the potting media mixture indorsed for the seedling growth are T12, T10 and T9.en_US
