Far-Red Radiation Reflected from Adjacent Leaves: An Early Signal of Competition in Plant Canopies
TL;DR: Results show the operation of a localized, photomorphogenetic control of stem elongation that may play a central role in the plastic adjustment of plants during the early stages of canopy development.

Environmental control of dormancy in weed seed banks in soil
Roberto L. Benech-Arnold,Rodolfo A. Sánchez,Frank Forcella,Betina Claudia Kruk,Claudio M. Ghersa +4 more
TL;DR: The different factors that affect dormancy in weed seed banks in soil are discussed, aiming to set a conceptual basis that will facilitate the construction of predictive models and stress the importance of clarifying the interaction between soil thermal and hydric conditions in the modification of the degree of dormancy of seed populations.

Early detection of neighbour plants by phytochrome perception of spectral changes in reflected sunlight
TL;DR: It is suggested that the change in the R: FR ratio within seedling canopies serves as an early warning signal of oncoming competition.

Effects of Light Quality on Tiller Production in Lolium spp.
TL;DR: Results show that branching of grasses is controlled by phytochrome activity in a way similar to that in dicotyledon plants.

Phytochrome A Mediates the Promotion of Seed Germination by Very Low Fluences of Light and Canopy Shade Light in Arabidopsis
TL;DR: It is proposed that phytochrome A mediates VLFR of A. thaliana seeds, which showed a strong low-fluence response when exposed to single red light (R)/far-red light (FR) pulses predicted to establish a series of calculated phy tochrome photoequilibria (Pfr/P).
