Bookmark or Share- Low red/far-red ratio as a signal promotes carbon ...However, a low red/far-red (R/Fr) ratio of light is a signal that affects plant growth in intercropping and close- planting systems. Thus, the low R/Fr ratio uncoupling from shading conditions was assessed to identify the effect of light quality on photosynthesis and CO 2 assimilation.
- Far-red light: A regulator of plant morphology and ...A high R/Fr ratio inhibits leaf expansion, resulting in a smaller leaf area. By contrast, a low R/Fr ratio increased leaf area by 1.31-fold compared with a control by increasing the extensibility of the cell wall in the plant cells (Fig. 2). Thus, leaf area influences radiation use efficiency.
- Exposure to lower red to far-red light ratios improve tomato ...Red (R) and far-red (FR) light distinctly influence phytochrome-mediated initial tomato growth and development, and more recent evidence indicates that these spectra also modulate responses to a multitude of abiotic and biotic stresses. This research investigated whether different R: FR values affect tomato growth response and salinity tolerance.
- Red and Far-red light: A tale of two spectrums - Greenhouse ...Phytochrome is a photoreceptor that senses red and far-red light. It is photo-reversible pigment, meaning that it changes forms depending on the light it senses. Phytochrome red (Pr) senses red light with a peak around 630 nm and, after sensing the red light, changes into phytochrome far-red (Pfr).
- Plant responses to red and far-red lights, applications in ...This review presents the state of the art in (i) perception of red (R) and far-red (FR) wavelengths and of the R:FR ratio by plants, (ii) phenotypic plant responses, and (iii) the molecular mechanisms related to these responses.
