Light response curves of photosynthesis, special leaf fresh weight, chlorophyll fluorescence at noon in field and under high light were determined in sun and shade leaves of 3 species of climbing plants.
以3种攀援植物为材料,测定其阳生、阴生叶片光反应曲线、比叶重、叶绿素荧光在中午自然条件下及人工强光照下的变化。
The results show that a sunlit leaf had a significantly higher photons flux density(PFD),net photosynthetic rate(Pn)than a shaded leaf at the same height.
基于多层二叶模型,在自然群体条件下,将棉花冠层分为上、中、下三层,研究淮北棉花花铃期冠层上、中、下层,阴叶(无直射光照射)与阳叶(有直射光照射)的光合特性的差异。
