Influence of tapping position, intensity of tapping and season on gummosis of guggal (Commiphora wightii), oleo-gum-resin yield and quality

Abstract

The experiment was conducted during 2009 and 2010 to find out different tapping position on the guggal plant [Commiphora wightii (Arn.) Bhand.] with varying intensity of tapping to maximize the gum production and tested them at different seasons to know the gum production potential as well as the quality changes with respect to different seasons. Favourable soil moisture and plant water status critically enhanced physiological functions which resulted in higher energy status, sap flow and turgor to enable gum oozing without break. Multiple tapping at different locations proved to be superior to single tapping. To maximize guggal yield, multiple tapping is needed at the right season. Wound created during tapping on the bark promoted wound response by inducing the resin ducts to release the oleogum to seal the wound.
