Dry-Matter Production by Evergreen Perennials

Nature, 1962
SOME 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 ...

Dry Matter Production by Detached Ears of Wheat

Nature, 1964
CEREAL yields have been shown to depend more on assimilation in the ears and flag leaves than on translocation into the grain of compounds manufactured or stored in other green parts of the plant1. Quantitative estimates of the relative contributions from the ears, the flag leaves or other green parts have been made by shading and defoliation methods2 ...

Dry Matter Production and Radiation Interception of Potato

Crop Science, 1991
The quantification of radiation‐use efficiency (RUE), the amount of dry matter produced per unit of intercepted photosynthetically active radiation, is important for yield modeling and determination of yield potentials in different environments. This study was conducted to determine the mean RUE value of potato (Solanum tuberosum L.) and its stability ...

Dry-matter Production and Photosynthesis in Pine Seedlings

Annals of Botany, 1966
Growth analysis and photosynthesis measurements were carried out on first-year seedlings of Pinus radiata , P. contorta , and P. nigra . P. sylvestris was also included in two growth-analysis experiments. There appeared to be no difference in relative growth-rate (RGR) between the species mentioned, except between P. radiata and P. nigra.

Some factors effecting the dry matter production of lucerne cultivars

Journal of the Grassland Society of Southern Africa, 1988
Dry matter yields of lucerne cultivars were affected by different factors. A simple equation is given for predicting total dry matter yield of irrigated lucerne based on mean maximum temperatures in January.Keywords: alfalfa; cultivars; dormancy rating; dry matter; dry matter production; dry matter yield; dry matter yields; environmental ...

Dry Matter Production of Hevea Clone Pb 260

The Planter, 2015
The study on the dry matter production of PB 260 was made on one-year-old to five- and three quarter-year- old trees during the immature phase and on eight-and-a-half-year-old to nineteen-and-a-half-year-old trees during the mature phase. All trees were located within the same vicinity on similar soil type, terrain and provided with similar management ...

Potential dry matter production of Miscanthus sinensis in The Netherlands

Industrial Crops and Products, 1992
Abstract The perennial C4-grass Miscanthus sinensis cv. ‘Giganteus’ is being advocated as a new biomass or fibre crop for north-western Europe. Above-ground yields of up to 40 tonnes of dry matter/ha/year have been claimed. Crop parameters of a fully-established M. sinensis stand were measured during the 1991 growing season.

Dry Matter Production of Trees at Timberline

1979
In the last chapter it was shown that growth of trees declines as one approaches the timberline, resulting in reduced stature and size of plant organs. This fall-off in growth could underlie an increasing shortage of organic materials, itself a consequence of deficient primary production.

Optimization of ethanol production from high dry matter liquefied dry sweet sorghum stalks

Biomass and Bioenergy, 2013
The ability of sweet sorghum to be utilized as feedstock for ethanol production at high initial dry material concentration was investigated. Sweet sorghum, after being dried, was liquefacted employing commercial cellulase solution Celluclast® 1.5L, in order submerged fermentation to be permitted under high-solids concentrations.

DRY MATTER PRODUCTION AND LIGHT INTERCEPTION OF CROP SURFACES

Grass and Forage Science, 1968
The growth curves of closed grassland swards obtained during the growing seasons of six successive years were compared with each other and with theoretical growth rates calculated by de Wit's method and based on the mean light energy input data for the same years.
