Dry Matter Production and Radiation Interception of Potato
Crop Science, 1991The 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, 1966Growth 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.

Measuring Coconut Palm Dry Matter Production
Experimental Agriculture, 1994Summary Non-destructive methods are described for estimating annual above-ground dry matter production by the coconut palm, Cocos nucifera. Leaf dry weight is estimated from the cross-sectional area of the petiole. Trunk dry weight increment is estimated from the volume increment, and a function relating trunk density to palm age. Husk and shell dry

Dry Matter Production by Detached Ears of Wheat
Nature, 1964CEREAL 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 ...

A Model of the Effect of Interspecies Competition for Light on Dry-Matter Production
Australian Journal of Plant Physiology, 1984A model of the effect of interspecies competition for light on the daily dry-matter production of competing species is developed. It describes the absorption of light by the component species, accounting for their different optical properties. Absorption equations are formulated from the principle of conservation of light energy within a unit-leaf-area-
