Estimating dry-matter accumulation in soybean
Canadian Journal of Botany, 1977Equations to estimate gross photosynthesis, respiration, and dry-matter accumulation for soybean from daily estimates of intercepted, photosynthetically active radiation (PAR) were developed from field measurements. We found that gross photosynthesis was a function of intercepted PAR and that 24-h dark respiration was a function of gross ...

Photosynthesis, Respiration, and Dry Matter Production
1976A full description of methods used in studying CO2-exchange and dry matter production is unnecessary, since a number of excellent reviews have been published on these subjects in recent years (Eckardt, 1968; Heath, 1969; Setlik, 1970; Sestak et al., 1971; Duvigneaud, 1971). With the exception of the last-named of these, the treatments pertain to plants

Dry-Matter Production by Evergreen Perennials
Nature, 1962SOME years ago, Heath and Gregory1 made the generalization that the mean net assimilation-rate was constant for species and environments. Subsequent work has demonstrated some large departures from their mean value of about 0.55 g/dm2/week, although Watson2 has more recently supported the validity of their general conclusion that leaf growth is the ...

Soil drying and organic matter decomposition
Plant and Soil, 1967A study was made of the effects of drying the soil at various temperatures on the subsequent mineralization of carbon, nitrogen and phosphorus of native and added organic matter in the soil.
