Use of an Optical Planimeter for Measuring Leaf Area.
The rapid, accurate measurement of area in biological materials of varying colors, textures, and shapes is of special concern to the plant scientist. The need for the measurement of leaf area, in particular, has prompted the search for newer and faster methods in recent years. In general, leaf area is an excellent indicator of the photosynthetic capacity of a plant and the measurement of such a...
متن کاملLeaf‐IT: An Android application for measuring leaf area
The use of plant functional traits has become increasingly popular in ecological studies because plant functional traits help to understand key ecological processes in plant species and communities. This also includes changes in diversity, inter- and intraspecific interactions, and relationships of species at different spatiotemporal scales. Leaf traits are among the most important traits as th...
متن کاملSuprachoroidal Air Injection for Detached Retina
INJECTION of air into the eye is considered by some authors to be useful in certain cases of detached retina (Spaeth, 1941). Where a considerable quantity of subretinal fluid has been evacuated, with consequent collapse of the globe, there are two ways in which the eye may regain its shape and tension. Either the subretinal fluid may re-form and reproduce the detachment, or aqueous may be forme...
متن کاملCosts of Measuring Leaf Area Index of Corn
Leaf area index (LAI) is an important biophysical descriptor of crop canopies. Accurate measurements of LAI are laborious and time-consuming. Many methods of measuring LAI of corn (Zea mays L.) have been reported and vary greatly in their accuracy, preclslon, bias, and ease of measurement. We examined the magnitude of plant-to-plant variability of leaf area of corn plants selected from uniform ...
متن کاملAs the Planimeter ’ s Wheel Turns : Planimeter Proofs for Calculus Class ∗
Tanya Leise ([email protected]) received her Ph.D. from Texas A&M University and is captivated by applied mathematics in many contexts, from accelerating cracks to biological clocks. Of particular interest to her recently has been the mathematics of mechanical devices such as astrolabes and planimeters, which are also great fun to collect. When not doing math, she enjoys cycling and sewing stu...
