Compared with high-stubble ratoon rice (RR), low-stubble RR is superior in yield potential, grain quality, and economic benefit. However, the unstable ratooning ability limits the grain yield of low-stubble RR production. Light condition during the g

Morphological and Pigment Responses to Far-Red and Photosynthetically Active Radiation in an Olive Cultivar Suitable for Super-High-Density Orchards

Autor: Federico J. Ladux, Carina V. González, Eduardo R. Trentacoste, Peter S. Searles, M. Cecilia Rousseaux

Publikováno v: Plants, Vol 13, Iss 13, p 1822 (2024)

Plant density is increasing in modern olive orchards to improve yields and facilitate mechanical harvesting. However, greater density can reduce light quantity and modify its quality. The objective was to evaluate plant morphology, biomass, and photo

LED Lighting: A Grower’s Guide to Light Spectra

Autor: John D. Stamford, Jim Stevens, Philip M. Mullineaux, Tracy Lawson

Publikováno v: HortScience, Vol 58, Iss 2, Pp 180-196 (2023)

For many growers, established and newcomers, the determination of the optimal light spectrum for growing crops can be challenging and highly dependent on crop species and variety. With the increased popularity of LED lighting, the capability to fine-

Modeling functional relationships between morphogenetically active radiation and photosynthetic photon flux density in mango tree crown

Autor: Emma Carrié, Isabelle Grechi, Frédéric Boudon, Elzbieta Frak, Didier Combes, Frédéric Normand

Publikováno v: Frontiers in Ecology and Evolution, Vol 11 (2023)

Light is a key factor in plant ecophysiological modeling because of its crucial effects on plant growth and development. However, solar light quantity and quality change with environmental factors such as sky condition and solar elevation. When passi

Polychromatic Fourier-PAM fluorometry and hyperspectral analysis of chlorophyll fluorescence from Phaseolus vulgaris leaves: Effects of green light

Autor: Vladimir Lysenko, Ya Guo, Alexey Kosolapov, Elena Usova, Tatyana Varduny, Vladimir Krasnov

Publikováno v: Information Processing in Agriculture, Vol 7, Iss 2, Pp 204-211 (2020)

Maximal and partial quantum yields of photosystem II (Fv/Fm and Fv–/Fp) in Phaseolus vulgaris leaves were determined in response to the turning on saturating and low (undersaturating) actinic light, accordingly. Measuring lights (ML) of blue, green
