ABSTRACT : To study the relationship between climate and phenology of plant operated in pine - dry dipterocarp forest permanent sample plot at Phu Toei national park, Suphan Buri 
province, by pursue phenology change of tree, the number 565 of 42 species, 1 time per month for 50 months bring. The phenology data was analysed to correlate with rainfall, high temperature, low temperature, average temperature and relative humidity by chi – square test with a weighted cases method. The test by Liner – by – Liner association at confidence level 95 percentage.
The result showed that the phenology of some species depends on the degree of temperature, 
relative humidity and rainfall, which the relationships are different. But, the most of relationships are medium level. However, only few species show the relationships with temperature only one. The study indicated that the climate might be impacted on the reproduction of some species 
of forest plant and might be caused to change to the structure of the forest in the future.
