Abstract:
OBJECTIVETo analyze the relationship between the net photosynthetic rate and the quality of Siraitia grosvenorii.
METHODTaken two species of S. grosvenorii: Yongqing No. 1 and Yehong No. 1 as the experimental material, CI-310 portable photosynthesis system was used to test the net photosynthetic rate in the late growth period; HPLC was used to determine momordica-glycosides V.
RESULTLight compensation point of Yongqing No. 1 was lower than that of Yehong No. 1 and the light saturation point was identical, the weight of dried fruit and the content of momordica-glycosides V of Yongqing No. 1 were higher than those of Yehong No. 1 at the late growth period.
CONCLUSIONThe net photosynthetic rate can be used as an important subservient index to assess the quality of S. grosvenorii.
