| Popis: | Fundamental studies have been initiated to develop the experimental system to investigate the effects of space environment on vegetative and reproductive growth of plants in their life cycles. In this study, thermal situation of plant reproductive organs as affected by illumination and air movement was accessed on the earth. Thermal images of reproductive organs of rice and strawberry were captured using infrared thermography at air temperatures of 10 to 11 C. Temperatures of petals, stigmata and anthers of strawberry increased by 24, 22 and 14 C, respectively, after lighting at an irradiance of 40 W/sq m under incandescent lamps. Temperatures of reproductive organs and leaves of strawberry were significantly higher than those of rice. The temperatures in petals, stigmata, anthers and leaves of strawberry decreased by 12.8, 11.9, 13.1 and 14.1 C, respectively, when the air velocity increased from 0.1 to 1.0 m/s. Air movement was essential to reduce the temperatures of plant reproductive organs in closed plant growth facilities. 資料番号: AA0063349109 |
