Study the best method of resin extraction from Pistacia atlantica trees.

This study was conducted from 2000-2002 to revnue and optimiz the method for resin extraction from Pistacia atlantica to minimize the minimum damage to these trees.This experiment was conducted as factorial randomized complete- block design.This research was based on Three groove factor in levels of( I0,20and 30 groove).the langht groove in three levels was ( 2,4 and 6 cm) . the position of the grooves were ( horizontal,vertical and diagonal) the effects of these factors were studied and observed on amount of quantitative, qualitative of freshness, color of left , annual growth of branches liner and wide growth factor of left.The best method to reduce minimum damage to these tree for extraction were according to 30-50 cm diameter (20 groove in 2 cm horizontal grooves).50-70 cm diameter (20 grooves in 4 cm vertical position ). 70-90 cm diameters 30 grooves in 4 cm horizontal in sequence. they were the best method to apply for resin extaraction product from Pistacia atlantica trees.
