Download or read book Leaf Area Index and Specific Leaf Weight written by Ram Oren and published by . This book was released on 1984 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Canopy Photosynthesis: From Basics to Applications written by Kouki Hikosaka and published by Springer. This book was released on 2015-12-17 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Trees in a Changing Environment written by Michael Tausz and published by Springer. This book was released on 2014-08-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers current state-of-the-science knowledge of tree ecophysiology, with particular emphasis on adaptation to a novel future physical and chemical environment. Unlike the focus of most books on the topic, this considers air chemistry changes (O3, NOx, and N deposition) in addition to elevated CO2 effects and its secondary effects of elevated temperature. The authors have addressed two systems essential for plant life: water handling capacity from the perspective of water transport; the coupling of xylem and phloem water potential and flow; water and nutrition uptake via likely changes in mycorrhizal relationships; control of water loss via stomata and its retention via cellular regulation; and within plant carbon dynamics from the perspective of environmental limitations to growth, allocation to defences, and changes in partitioning to respiration. The authors offer expert knowledge and insight to develop likely outcomes within the context of many unknowns. We offer this comprehensive analysis of tree responses and their capacity to respond to environmental changes to provide a better insight in understanding likelihood for survival, as well as planning for the future with long-lived, stationary organisms adapted to the past: trees.

Download or read book Leaf and canopy development of mangosteen (Garcinia mangostana L.) grown under natural shade trees written by Masri Muhamad and published by . This book was released on 1994 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaf and canopy development were studied on 30-months old mangosteen (Garcinia mangostana L.) plants grown under the shade trees of Indigofera tasmania and were compared to those grown without shade. Results showed that shaded trees had significantly wider canopy spread (73.9 cm) as compared to unshaded ones (62.7 cm). Similary, canopy growth rate of shaded trees had only 1.48 cm/month canopy growth rate. The average leaf size of the shaded plants was 140.3 cm2 as compared to 94.4 cm2 for unshaded controls. However, the specific leaf weight were lower for the shaded trees.In terms of leafs growth, leaf length development of shaded plants were significantly faster and matured two weeks earlier than the unshaded leaves. Results of the study suggest that mangosteen trees grown under shade condition had better leaf and canopy growth as compared to those exposed to without shading. [Author's abstract].

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the role of meristematic tissues in plant growth and development, with an emphasis on advances of the last decade. It examines meristematic tissues as a defined, independent tissue type in plants and gives consideration to their origin, maintenance, and function. The editors pay particular attention to the molecular mechanisms underlying meristem formation and maintenance. This volume is a tremendously valuable resource for plant geneticists, developmental biologists, and molecular biologists.
