Abstract: The effects of triterpene acids from fir needles on growth,yield and quality of ‘Difeni’ tomato were studied by the method of spraying leaf surface.Preliminary results showed that the triterpene acids could promote tomato growth,increase stem diameter and fruit-setting rate,and the yield of tomato was increased by 8.7%in comparison with water control.The triterpene acids could also increase dry mass,vitamin C,soluble protein and soluble sugar contents,and decrease titratable acid(TC) contents in the fruit.The mixture of triterpene acids and Azoxystrobin & Chlorothalonil(A&C) were more efficient,to improve the productivity.

Key words: fir, triterpene acid, tomato, yield, quality
