The development of a procedure to calculate the effect of certain environmental factors on the rate of photo-synthesis imposed mainly geometrical problems, which were solved in such a way that the actual calculation could be carried out by means of a computer. The calculation procedures have been used to study the. relative importance of the variables under various conditions. The results for a standard set of conditions, have been summarized in order to make it possible to estimate the daily photosynthesis at any time and place for a wide range of photosynthesis functions without a computer.

The last 30 years has seen the development of increasingly sophisticated models that quantify canopy carbon exchange. These models are now essential parts of larger models for prediction and simulation of crop production, climate change, and regional and global carbon dynamics. There is thus an urgent need for increasing expertise in developing, use and understanding of these models. This in turn calls for an advanced, yet easily accessible textbook that summarizes the “canopy science” and introduces the present and the future scientists to the theoretical background of the current canopy models. This book presents current knowledge of functioning of plant canopies, models and strategies employed to simulate canopy function, and the significance of canopy architecture, physiology and dynamics in ecosystems, landscape and biosphere.

Two physiological factors are of major importance to tree and stand growth: (1) the photosynthetic rate of foliage and (2) the amount of foliage. If carbohydrate allocation patterns remain constant, stand growth should be related directly to total canopy photosynthesis. From a literature analysis I assess methods of relating photosynthetic rates to biochemical, anatomical, and structural characteristics of foliage. A number of these foliage characteristics were found to be interrelated. Specific leaf weight was shown to be a valuable index for comparing photosynthesis by various parts of a tree canopy over a season or throughout an entire year. Mean annual photosynthetic rate in five separate portions of a spruce canopy was directly proportional to observed differences in specific leaf weight (r2 = 0.99). Annual carbon uptake was a function of total foliage biomass (r2 = 0.96). When foliage biomass at each crown segment was adjusted for differences in specific leaf weight, reflecting differences in photosynthetic rates, the predictive equation further improved C r2 = 0.99). Specific leaf weight is recommended as an index for comparing the relative effects of various silvicultural treatments on photosynthesis. I then evaluated how stand growth and canopy leaf area were related by analyzing 24 years of growth records from a Pinus ponderosa (Laws.) experiment. The experiment included a wide range in initial stocking and partial control of understory vegetation (Barrett 1982). I found that treatment effects on tree growth can be evaluated at low values of stand leaf area from comparison of growth efficiencies (wood produced per unit leaf area) among plots of similar canopy leaf area. By comparing stand growth with stand leaf area, I concluded that the major effect of removing understory vegetation was to speed the development of the canopy. This interpretation was also supported by a comparison of the rate of leaf area development on plots with and without understory vegetation at comparable levels of canopy leaf area. Comparing stands at a similar canopy leaf area is advised for assessing how treatment affects stand development. This is a valuable alternative to analyzing treatment effects at one point in time and helps to explain the results of many fertilization experiments.

Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.
