Chinese Pistache(Pistacia chinensis Bunge)is regarded as an important woody oil plant and timber tree in China.A provenance test was conducted to measure and make the comparative analysis of the index of photosynthetic rate,transpiration rate,leaf area and height of growth of the two-year-old Chinese Pistache seedlings,which grew from the seeds collected from five provenances.The results showed that among the five provenances,the seeding of Chuzhou of Anhui Province demonstrated the bigget total average daily values in terms of net photosynthetic rate and evaporation rate,which were 10.7 μmol·m-2·s-1 and 3.4 mmol·m-2·s-1 respectively.The leaf area and plant height of the provenance of Chuzhou of Anhui were larger than those of the other four provenances.The provenance test came to a primary conclusion that the seedlings from Chuzhou Prefecture of Anhui Province was the best among the five provenances in terms of the net photosynthetic rate,transpiration rate,leaf area and plant growth.
