ABSTRACT
<p><b>OBJECTIVE</b>To study the photosynthetic characteristics and chlorophyll fluorescence parameters of Pinellia ternate from different sources, in order to provide basis for cultivation and breeding.</p><p><b>METHOD</b>Pigment contents were compared among different sources by the Lichtenthaler method. The light-response and diurnal photosynthesis course of P. ternata from different sources were analyzed by LI-6400 system, and chlorophll fluorescence parameters were analyzed by PAM-2100 system.</p><p><b>RESULT</b>The difference of photosynthetic characteristics among the sources were remarkable. The light compensation point (LCP) of P. ternate from different sources were 11.57-17.88 micromol x m(-2) x s(-1), the light saturation point (LSP) were 1 000-1 300 micromol x m(-2) x (s-1). All the sources have obvious "midday depression". P. ternate cultivated in Xinjiang showed a higher light saturation point (LSP) and better chlorophyll fluorescence parameters.</p><p><b>CONCLUSION</b>P. ternata cultivated in Xinjiang showed better photosynthetic characteristics and chlorophyll fluorescence parameters than the others.</p>
