Elliott, K.J. and White, AS., 1993. Effects of competition from young northern hardwoods on red pine seedling growth, nutrient use efficiency, and leaf morphology. For. Ecol. Manage., 57. 233255. The effects of competition from three northern hardwood tree species on red pine (Pinus resinosa Ait. ) seedlings were examined on two clear-cut sites in western Maine. We examined how planted red pine...
Mulberry (Morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, Bombyx mori L. Mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. Leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...
Abstract Estimation of crop water stress index (CWSI) and leaf area (LAI) over large-irrigation schemes requires the use cutting-edge technologies. Combinations remote sensing techniques with ground-truth data have become available for at catchment level. These approaches allow us to estimate actual evapotranspiration capability monitoring status saving irrigation in water-scarce regions. This ...

Non-destructive estimation using digital cameras is a common approach for estimating leaf area index (LAI) of terrestrial vegetation. However, no attempt has been made so far to develop non-destructive approaches to LAI estimation for aquatic vegetation. Using the submerged plant species Potamogeton malainus, the objective of this study was to determine whether the gap fraction derived from ver...
