  1. Effects of photosyntheynthetic photon flux density and co2 concentration on photosynthesis of sugar - free micropropagation of sweetpotato plantlets

    2濃度間接調控對甘薯無糖組培苗光合特性的影響
  2. Pms has no obvious relation to age and has good relation to air temperature, photon flux density and air humidity. the pre - dawn pms is steady. compared with caraganar, the drought - resistance ability of s. viciifolia is stronger

    枝水勢同年齡之間無明顯關系，與環境因子間有很好的響應，同大氣溫度和光照顯著負相關，與大氣濕度顯著正相關。
  3. Photosynthesis and transpiration have no obvious difference between different age s. viciifolia, but they have consanguineous physiological responses to environmental factors such as photon flux density, air temperature and the content of soil water. compared with caraganar, s. viciifolia formed the physiological mechanics of less photosynthetic rate and less tranpiration rate to resist drought

    狼牙刺的凈光合速率同光合有效輻射、大氣溫度和二氧化碳濃度之間沒有顯著相關性，與土壤含水量顯著正相關；蒸騰作用與光合有效輻射、土壤含水量及空氣溫度有很好的正相關性，與大氣濕度有負相關性。
