摘要
The production of resin from pinus trees is an important activity in many countries, with both economic and social benefits. It provides terpenes, which are used in the chemical industry. The present work proposes a new process of using endophytic fungi isolated from Pinus massoniana Lamb. to increase resin yield by using the bark streak method of wounding. Ten strains of endophytic fungi isolated from roots, stems and leaves of P. massoniana were investigated. Stimulant pastes were created from the fermentation broths of the ten endophytic fungi, as well as a mixture of fungi. The resin yield of the trees was measured with and without endophytic fungus application. The results showed that each of the ten strains could increase the resin yield of the P. massoniana. The rate of increase of the resin yield of the trees with the mixed fermentation broths of the ten endophytic fungi was the highest (40.83%). The resin tapping after endophytic fungus application had a higher increasing rate of the resin yield than that with a chemical stimulant paste, while avoiding pollution to the environment or harm to humans or livestock. This research indicates that the endophytic fungus can be an effective alternative to chemical stimulants, and will become a new type of stimulants in resin tapping.
