The latest research on the application of antitranspirant in forestry was reviewed, including the effects of applying antitranspirant on some physiological and biochemical mechanisms of trees such as transpiration rate,photosynthetic rate, leaf water potential,changes of chlorophyll content,etc. and on the contents of chemicals responding to drought stress. At same time,the authors described the effects of applying antitranspirant on increasing survival rate of afforestation and big tree transplanting, impr...
