| 摘要: |
| 罗汉果试管苗在不同波长的LED(半导体)蓝(475±5 nm)、黄(585±5 nm)、红(660±5 nm)及普通日光灯下培养,25 d后观测发现,其外观的优劣依次为:蓝光>白光>红光>黄光; 植株重量:蓝光>红光>黄光>白光; 蓝光和白光下的植株叶大、色绿,植株矮壮,侧芽多; 红光和黄光下的植株叶小、色黄绿,植株高、细、弯曲、节间长。测定罗汉果成熟叶片的吸收光谱,发现在波长380～500 nm及660～680 nm处有较强吸收。不同的光质下测定成熟叶片光合速率,大小依次为:红光>蓝光>白光>黄光。上述的各项试验表明,蓝光对罗汉果幼苗生长发育最好; 红光和蓝光为成熟叶片光合作用的最佳光源。 |

| Abstract: |
| The test-tube plantlets of Siraitia grosvenorii were cultivated under different wavelength lights(blue light 475±5 nm; yellow light 585±5 nm; red light 660±5 nm and white light). Growing condition was observed after 25 days. The morphological characters were arranged:blue light>white light>red light>yellow light. Weight of single plantlet was:blue light>red light>yellow light>white light. Under blue and white lights,seedlings have large and deep green leaves,short and thick stems with more lateral buds. While under red and yellow lights,the leaves were small and yellow green; the stems were long,crook and thin. Based on the absorption spectrum of its ripe leaves,two strong absorption areas were found in 380～500 nm and 660～680 nm. The photosynthetic rates under different lights were in the order:red light>blue light>white light>yellow light. All these results indicated that blue light was best for growth and development of young seedling of Siraitia grosvenorii. While the red and blue lights were suitable for photosynthesis. |
