内容記述 |
Phalaenopsis and its hybrids are the most important orchid pot plant commercially in the world now. Research on photosynthesis gives us practical and useful information for improving cultivation. Although conventional gas-exchange technique has some limitations in the research of a crassulacean acid metabolism plant (CAM), we investigated CO_2 uptake in Phalaenopsis. CO_2 uptake at night (Phase 1) changed with temperature. Maximum CO_2 uptake was observed around 20℃. CO_2 absorption at night increased in proportion to CO_2 concentration. Rate of CO_2 absorption was higher at 20℃ than at 25℃. CO_2 uptake in the late afternoon (Phase 4) showed a maximum around 20℃. CO_2 absorption in Phase 4 increased in proportion to CO_2 concentration but stomata conductance decreased under high CO_2 levels. CO_2 absorption response curve to light intensity in Phase 4 was not saturated till 500 umol.m^<-2>.s^<-1> PPFD when CO_2 level was 2000 ppm, and then the stomata conductance showed very low values. Under various water and humidity condition when Phalaenopsis was irrigated weekly, CO_2 uptake in Phase 1 was the largest at one day before watering, but that of Phase 4 was the largest at one day after watering. Total CO_2 uptake in all Phases was stimulated the most at 70% relative humidity and suppressed drastically at 30% relative humidity. These results indicated that higher relative humidity is likely the most important factor for high CO_2 absorption in Phalaenopsis. |
