Temperature Effects on the Photosynthesis by the Medicinal Plant Pinellia ternata Breit

We investigated the effect of air temperature on the growth of the medicinal plant Pinellia ternata Breit. collected from the four prefectures, Fukushima, Kyoto, Nagasaki, and Okinawa prefectures. Plants were grown for 15 weeks in phytotrons controlled at air temperatures of 20, 25, and 30°C. In the...

Description
Summary:We investigated the effect of air temperature on the growth of the medicinal plant Pinellia ternata Breit. collected from the four prefectures, Fukushima, Kyoto, Nagasaki, and Okinawa prefectures. Plants were grown for 15 weeks in phytotrons controlled at air temperatures of 20, 25, and 30°C. In the Kyoto lines, the highest corm yield was observed at 25°C, whereas the corm yields in Fukushima, Nagasaki, and Okinawa lines did not differ significantly with respect to yield among the three growth temperature conditions. Therefore, in this study, the temperature effects on the photosynthesis by P. ternata collected from the three prefectures of Kyoto, Nagasaki, and Okinawa were investigated. Obvious effects of air temperatures were not observed in the plant photosynthesis for all regions. Thus, air temperature does not affect the yield through the photosynthesis in the P. ternata.
