- Abstract
To investigate the phenotypic variation of cucumber photosynthesis, net photosynthetic efficiency of cucumbers were measured by LI-6400XT Portable Photosynthesis System. Non-rectangular hyperbolic model was adopted to fit the light response curve. We used 16 cucumber accessions selected from the core collection that consists of over 400 accessions. As a result, cucumbers show a moderate variance in the phenotype of light compensation point (LCP), light saturation point (LSP) and apparent quantum efficiency (AQY), dark respiration rate (Rd), and maximum net photosynthetic rate (Amax). In a detail, the coefficient of variation (CV) of LCP and Rd is 48.97% and 48.09%, respectively, which is relatively high. In contrast, the CV values of Amax, LSP and AQY are all smaller than 25%. These results help us get better understanding about the phenotypic variation of photosynthesis in cucumber germplasm.
