Effect of Reflective Film Mulching on the Stomatal Features, Transpiration Rate and Photosynthetic Rate of Tomato Plants in Greenhouse Cultivation
반사필름 멀칭이 토마토의 기공특성, 증산속도, 광합성속도에 미치는 영향
Abstract
These studies were conducted to verify the effect of the supplementary lighting by reflective film mulching and its establishment in the north side of greenhouse on the utility of light at tomato by means of investigating changes of leaf temperatures, stomatal features, transpiration rates and photosynthetic rates. Stomatal density of leaves were high in the reflective film mulching but sizes of stomata were not different. As the osmotic potential in rooting zone was low, the stomatal resistance was high, transpiration rate was low, and leaf temperature was increased by 40.62
본 연구에서는 반사필름 멀칭과 북측면의 반사판설치에 의한 보광이 토마토의 광이용에 미치는 영향을 밝히기 위해 토양 및 수경재배를 통해 토마토의 엽온변화, 기공특성, 증산.광합성속도 등의 변화들을 중심으로 검토하였다. 보광 처리에 의해 토마토엽의 기공밀도는 증가하였으나 기공의 크기와 면적은 차이가 얼었다. 근권부의 삼투포텐셜이 낮으면 광반사에 의한 기공저항이 컸고 증산속도는 낮았으며 엽온은 40.62
