Photochemical efficiency of basil cultivars fertigated with salinized nutrient solutions

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
Reduction in plant growth under salt stress is due, among other factors, to changes in photochemical efficiency and, consequently, in photosynthesis. The objective of this study was to evaluate the effect of salt stress on the chlorophyll fluorescence ...

New approaches to the measurement of chlorophyll, related pigments and productivity in the sea [PDF]

open access: yes
In the 1984 SBIR Call for Proposals, NASA solicited new methods to measure primary production and chlorophyll in the ocean. Biospherical Instruments Inc. responded to this call with a proposal first to study a variety of approaches to this problem.
