Growth and dry-matter partitioning of young Populus trichocarpa in response to carbon dioxide concentration and mineral nutrient availability.
Young individuals of a single black cottonwood (Populus trichocarpa Torr. & Gray) clone were raised for three growing seasons in whole-tree chambers and exposed to either ambient or elevated atmospheric carbon dioxide concentration ([CO2]), with either a high or a low mineral nutrient supply, in a factorial experimental design. Nutrient availability had a larger effect on growth and dry matter ...
متن کاملReproductive Growth and Dry Matter Production of Glycine max (L.) Merr. in Response to Oxygen Concentration.
Reproductive as well as vegetative parameters of mature soybean (Glycine max [L.] Merr. cv. Wye) plants grown in chambers in which the aerial portion was exposed to altered pO(2) during all or part of the growth cycle were measured. Oxygen concentration was found to be a key factor controlling all phases of reproductive development. Exposure to 5% O(2) from early seedling stage to senescence in...

متن کاملdry matter partitioning, growth analysis and water use efficiency response of oats (avena sativa l.) to excessive nitrogen and phosphorus application
shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...
متن کاملEffect of reducing dietary mineral content on growth performance, water intake, excreta dry matter content and blood parameters of broilers.
1. The objective of this study was to investigate whether it is possible to reduce phosphorus (P) excretion by feeding a lower level of dietary P than that currently recommended, without compromising welfare, and whether this is sensitive to the level of dietary calcium (Ca). 2. A randomised complete block design was used with a total of 224 1-d-old male chicks of a commercial genotype in two b...
