Thermal adaptation of net ecosystem exchange [PDF]

open access: yes, 2011
Thermal adaptation of gross primary production and ecosystem respiration has been well documented over broad thermal gradients. However, no study has examined their interaction as a function of temperature, i.e.

Analytical Procedure for Estimation of the Assimilation Cell Phase CO2 Mass Transfer Coefficient of Crop Leaf from Experimental Measurements of the Net Photosynthetic Rate

open access: yes, 1999
Analytical solutions for the CO2 concentration profile CA (z, t) and CO2 mass transfer coefficient kL within the assimilation cell phase of the crop leaf in the net photosynthesis process were obtained by the concept of “rate of process” in the ...

A provisional survey of the interaction between net photosynthetic rate, respiratory rate, and thallus water content in some New Zealand cryptogams

open access: yes, 1980
The effect of water content on photosynthetic and respiratory rates in eight lichen species and one bryophyte species were studied using an injection infrared gas analyser technique. All species snowed a strong relationship between net assimilation rate (

Response of net CO2 assimilation rate to intercellular CO2 concentration for R and S families of limber pine.

open access: yes, 2016
Curves were taken at a leaf temperature of 25°C, PPFD of 1,800 μmol photons m-2 s-1 and leaf-to-air vapor pressure difference of 1.6 kPa; net CO2 assimilation rate is expressed on a total leaf surface area basis. Statistically significant differences are
