| Research Abstract |
We investigated the photosynthetic function of tomato canopy cultivated in large-scaled greenhouses of five tomato production companies, i.e. Iwaki-onahama saien (Fukushima pref.), Sera saien (Hiroshima pref.), Kata saien (Wakayama pref.), Shimanto-mihara saien (Kochi pref.) and Hibikinada saien (Fukuoka pref.). The photosynthetic functions of the tomato canopies were varied among the greenhouses in spite of the same cultivar in the same cultivation process. Especially, the difference in the photosynthetic ability of single leaf evaluated by measuring light response curve was provably due to the difference in CO2 enrichment. And, we proved that the photosynthetic functions of the tomato canopies in Iwaki-onahama saien and Shimanto-mihara saien showed significant seasonal changes and the extents of the seasonal changes were different from each greenhouse.
