The light spectrum for plant cultivation: a source of colourful arguments

Pedro José Aphalo, Titta K Kotilainen

Subjects: Agriculture, Food Science, Life Sciences

The concept of ``wasted illumination'' and its application to the design of light sources for plant cultivation is a good example of misuse of reductionism. Equating instantaneous rate of photosynthesis to crop yield is a prevailing but nonsensical idea, and in the case of the design of red plus blue light sources an extreme case of ignoring the multiple regulatory mechanisms and interactions [...]

An alternation between diploid and haploid phases is universal among sexual eukaryotes. Across this biphasic cycle, natural selection and sexual selection occur in both phases. Together, these four stages of selection act on the phenotypes of individuals and influence the evolutionary trajectories of populations, but are rarely studied holistically. Here, we provide a conceptual framework that [...]
