, 1974 The diurnal relationship between xylem pressure potential and stem diameter in white oak (Quercusalba L.) resulted in a hysteresis loop on clear days where, for a given level of xylem pressure potential, the stem was thinner upon rehydration than during

Rates of net assimilation and respiration of amino acids by marine bacteria
Journal of Oceanography, 1974The selectivity of amino acid assimilation by marine bacteria was examined using seven kinds of14C-amino acids and the acid hydrolysate of14C-labelled proteins. It was found that the net assimilation and respiration by marine bacteria followed MICHAELIS-MENTEN kinetics for all of amino acids used in our experiments.

High rates of net ecosystem carbon assimilation by Brachiara pasture in the Brazilian Cerrado
Global Change Biology, 2004AbstractTo investigate the consequences of land use on carbon and energy exchanges between the ecosystem and atmosphere, we measured CO2 and water vapour fluxes over an introduced Brachiara brizantha pasture located in the Cerrado region of Central Brazil.

Relation of Magnesium Supply to Growth and Net Assimilation-rate in Barley
Nature, 1955IN recent years attention has been directed to the increasing incidence of magnesium deficiency in crop plants1, and it is also possible that such a deficiency may cause disease in ruminants grazing on affected herbage2. Using the methods of growth analysis3, a study is being made of the effect of this element on carbon assimilation in plants.

Growth and net assimilation rates in thinned and unthinned stands of balsam fir
Canadian Journal of Forest Research, 1988Current annual stem growth rates per hectare of unthinned young stands of balsam fir (Abiesbalsamea (L.) Mill.) were 2–3 times greater than in adjacent stands thinned 4–6 years earlier, largely because unthinned stands contained 2.5–4.0 times more foliar weight per hectare. Stem growth rates per tree in thinned stands were 3–8 times greater than those

Annals of Botany, 1994
Abstract Previously it has been established that when mean relative growth rate (RGR) is estimated from growth data by the classical method of growth analysis, the computed variance of RGR is probably greater than it should be. By similar procedures, it is now demonstrated that the same is true of unit leaf rate (ULR).

Effects of shading and time of year on net assimilation rates of young glasshouse tomato plants
Annals of Applied Biology, 1967SUMMARYMinimum and maximum net assimilation rates were determined from calculated curves of closest fit to data for 2 years. The minimum (14 g./m.2/week) occurred in mid‐December, immediately before the shortest day, and the maximum (78 g./m.2/week) between 27 June and 8 July, just after the longest day.
