LI-6400XT System Tech Tip: Dealing with Large Moist Samples

Tuesday, February 28th, 2012

With large chambers such as the 6400-24 Bryophyte Chamber, the 6400-05 and 6400-22 Conifer Chambers, or a large custom chamber, it is possible to measure large samples. An advantage of large samples is that larger CO2 differentials are possible, even at lower photosynthesis rates, leading to higher precision in the photosynthesis measurement. With large moist…

Undergraduates Learn with the LI-6400XT, Thanks to LEEF Grants

Faster Field Measurements of A_sat

Wednesday, August 31st, 2011

Introduction Measurement of the light-saturated rate of net CO2 fixation under ambient conditions (Asat ) is an important physiological parameter for the investigation of genetic differences in plant breeding programs, ecological studies, and response to environmental stresses or chemical treatments. To obtain a reliable mean value of Asat for a plot, treatment or species, numerous…
