Abstract: The quality is the most important indicator to evaluate whether a species is successfully introduced.The appraisal of the Jatropha curcas quality included oil rate,characteristic of seed oil and diesel.Based on weather data of different site and time and the correlation data of the Jatropha curcas seed,this paper studies the impact of different weather condition on the Jatropha curcas quality by statistics and contrast analysis.The results showed that the quality responses of Jatropha curcas to temperature and sunshine are more obvious.The Jatropha curcas is more drought tolerant and hot habitatpreferredAdequate light brings high seed oil.Heat temperature conditions are the most important climatic and ecological environmental factors to affect the geographical distribution of Jatropha curcas,and the key conditions to affect the level of Jatropha curcas seed oil content,which ultimately affect the quality of Jatropha curcas

Key words: Jatropha curcas, The weather condition, Quality
