Explaining growth of individual trees: Light interception and efficiency of light use by Eucalyptus at four sites in Brazil
The growth of wood in trees and forests depends on the acquisition of resources (light, water, and nutrients), the efficiency of using resources for photosynthesis, and subsequent partitioning to woody tissues. Patterns of efficiency over time for individual trees, or between trees at one time, result from changes in rates photosynthesis and shifts in the relative partitioning to wood. We measu...

in order to evaluate the effect of sugar beet sowing date, planting density and cultivar on solar radiation interception, a study was conducted in kamal-abad agricultural research station of sugar beet seed institute (sbsi) in 2005 and 2006. the experimental design was split-split plots based on randomized complete block design (rcbd) with three replications with two sowing dates as the main pl...
متن کاملGreen-light supplementation for enhanced lettuce growth under red- and blue-light-emitting diodes.
Plants will be an important component of future long-term space missions. Lighting systems for growing plants will need to be lightweight, reliable, and durable, and light-emitting diodes (LEDs) have these characteristics. Previous studies demonstrated that the combination of red and blue light was an effective light source for several crops. Yet the appearance of plants under red and blue ligh...
متن کاملImproving spinach, radish, and lettuce growth under red light-emitting diodes (LEDs) with blue light supplementation.
Radish (Raphanus sativus L. cv. Cherriette), lettuce (Lactuca sativa L. cv. Waldmann's Green), and spinach (Spinacea oleracea L. cv. Nordic IV) plants were grown under 660-nm red light-emitting diodes (LEDs) and were compared at equal photosynthetic photon flux (PPF) with either plants grown under cool-white fluorescent lamps (CWF) or red LEDs supplemented with 10% (30 micromoles m-2 s-1) blue ...
