中文摘要 | 玫瑰花Rosa multifrora `K-2'、Rosa indica `Major'、Rosa hybrida ` Samantha'、`Landora' 之植株,栽培在不同溶氧量之水耕液中, 生長在高氧組之水耕液中 的植株,枝條的生長速率明顯比中氧組與低氧組植株為快,而地上部枝條之鮮、乾重高氧組 亦明顯要較中、低氧組為重。`Landora' 植株葉片之光合作用率明顯會因養液中低溶氧量而 受到抑制。低氧組植株在高溫下 (34 ℃ ),葉片上的氣孔為閉合,而高氧組則為打開。 |
英文摘要 | Plants of Rosa multiflora `K-2"、Rosa indica `Major'、Rosa hybrida Samantha'and `Landora' were cultured in solutions with different oxygen content. The shoot elongation of rose plants cultured in high oxygen (7-8ppm) solution was quicker than that cultured in low oxygen (3-4ppm) solution. the fresh weight and dry weight of rose plants cultured in high oxygen solution were also heavier than that cultured in low oxygen solution. The photosynthesis of `Landora' plant was inhibited when plant cultured in low oxygen solution. There were closing stomata of rose plant cultured in low oxygen solution under high temperature (34 ℃ ), when there were opening stomata of rose plant cultured in high oxygen solution. |
