1 NETWORK PROJECT ON HARVESTING, PROCESSING AND VALUE ADDITION OF NATURAL RESIN AND GUMS CENTRE: Department of Forest Products, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) Crop/Activity assigned: Rosin (Oleoresin from Chirpine) NAME OF INVESTIGATORS: Principal Investigator: Co-PI: Dr Kulwant Rai Sharma Dr Bhupender Dutt OBJECTIVES To carry out survey for collection and documentation of information on present status of production, processing, marketing, utilization & characterization of gum arabic, guar gum, karaya gum, guggul and rosin. Identification of technological gaps in harvesting/tapping, post harvest processing and value addition of gum Arabic, guar gum, karaya gum, guggul and rosin. To develop agro-forestry models based on gum, resin and gum-resin trees.. Salient achievements of the centre: Bore Hole Method', a new method has been experimented and standardized. This method involves drilling holes into the wood to open the maximum number of resin ducts. The advantages of this technique over conventional methods include higher labour productivity, improved product quality and reduced tree stress. The tree diameter and number of boreholes has significant effect on oleoresin yield. Highest oleoresin yield has been obtained from 40-45cm and cm diameter class. High resin yielders have maximum number of vertical and horizontal resin ducts. The number of epithelial cells in vertical and horizontal resin ducts was found to be highest in high resin yielders as compare to medium and low resin yielders. Oleoresin yield was highly significantly and positively correlated with needle thickness, needle length, number of vertical resin ducts, diameter of vertical resin ducts, number of epithelium cells in a vertical resin duct, number of horizontal resin ducts, diameter of horizontal resin duct and number of epithelium cells in a horizontal resin duct. Experiment has been laid out on resin tapping potential of chir pine progenies of superior trees. Among 22 progenies of Pinus roxburghii selected for tapping, Kopra- P5 has performed best in oleoresin yield ( g/season).

2 Higher oleoresin yielders have been recorded in progenies having dark green (136 A) needle colour, followed by green (137 B) needle colour. Progenies with yellowishgreen (145 A) needles have given lowest oleoresin yield. The trees with yellow (13 B) colour oleoresin are found to be higher yielder, followed by trees with yellowish-white colour (10 B). Trees with white (155 A & B) colour oleoresin have been observed to be poor yielder. The progenies with yellow colour oleoresin have been found to be higher yielders and trees with white colour oleoresin have been found to be poor yielders. Highest turpentine content was recorded in yellow colour oleoresin in the month of May and lowest turpentine content was observed in white colour oleoresin in the month of September, whereas, the maximum rosin content was recorded in white colour oleoresin.
