dc.description.abstractABSTRACT The present investigation entitled “Effect of chemical stimulants on oleoresin production and wood quality of Pinus roxburghii Sargent” was undertaken in the Department of Forest Products, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-173230 (HP) during 2020-2022 with the objectives to find out the effect of chemical stimulants and methods of tapping on oleoresin production and quality, effect of chemical stimulants on wound healing of Borehole and Rill method and effect of methods of oleoresin tapping on the wood quality of Chir Pine respectively. Among the different chemical stimulants used for oleoresin tapping, treatment T7 (20 per cent H2SO4 + 20 per cent HNO3) showed best results for oleoresin yield. Healing rate in both Boreholes and Rill tapped blazes of Pinus roxburghii trees ranged from 4.64 (2.37) per cent to 96.25 (79.34) per cent. In contrast to traditional methods, where healing of these Boreholes and Rill tapped blazes takes at least 2-3 years and 20-30 years respectively, but by the application of new chemical stimulants, especially auxins like NAA (Napthalene Acetic Acid), rapidly healed the Boreholes and Rill tapped blazes within a year. Oleoresin tapping methods had significant effects on physical, chemical, and anatomical factors associated with wood quality. In order to improve oleoresin yield and wound healing, different chemical stimulants can be tailored and modified such as CEPA can be replaced with NAA, which can be used in combination with sulphuric acid which helps in prolonged resin flow. NAA is an auxin that aids in cell differentiation and growth leading to rapid healing of wounds caused by tapping, which could result in eco-friendly sustainable practices to ensure the long-term health and productivity of trees.
