Leaf area index measurements
Leaf area index (LAI) is a key structural characteristic of forest ecosystems because of the role of green leaves in controlling many biological and physical processes in plant canopies. Accurate LA1 estimates are required in studies of ecophysiology, atmosphere-ecosystem interactions, and global change. The objective of this paper is to evaluate LA1 values obtained by several research teams us...
متن کاملenvironmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Variation in parameters related to leaf thickness in common bean (Phaseolus vulgaris L.)
Greater leaf thickness is usually associated with greater leaf carbon assimilation rate, but the tradeoff between thicker versus larger leaves also affects canopy structure and light interception. Many studies equate the ratio of dry leaf mass to area (leaf specific mass) with leaf thickness. This approximation has utility but ignores differences in true thickness due to variation in water or a...
متن کاملOn the Origin of the Common Bean (Phaseolus vulgaris L.)
Phylogeographic methods provide the tools to accurately access the geographic origin and diversification of crop species. In the present commentary, I urge the common bean community to face those methods and a tree-thinking mentality with regards to the long standing debate of the origin of common bean. Such efforts will ultimately bring back interest into wild bean studies and reinforce the un...
متن کاملLeaf Area, Leaf Area Index and Light Extinction Coefficient for Taro Culture
Taro, Colocasia esculenta (L.) Schott, is the most important species from the Araceae family. The leaf area (LA) is important for the interception of solar radiation and for the biomass production. The light extinction coefficient (k) is related to the leaf inclination angle, leaf arrangement, regarding the Leaf Area Index (LAI), providing an indication of the plants efficiency on intercepting ...
