Measurements of the rate of photosynthesis of plants of Solanumtuberosum L. var. King Edward were made, using 14CO2, at weeklyintervals throughout their growth in a controlled environment.Leaf area and dry weight of sections of the plant were alsodetermined. The results are discussed in relation to existingtheories that photosynthesis can be limited by carbohydrateaccumulation in the leaves, and stimulated by the initiationof tubers.  相似文献
