Fluorescence bands and chlorophyll a forms

Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964
Abstract Fluorescence spectra were determined at temperatures between 20° and −196° for a number of photosynthetic organisms. Below −90° the single fluorescence maximum around 685 mμ was replaced by a system of three bands, at 686, 696 and 717–720 mμ in algal cells. Cooling usually resulted in a decrease of the 685-mμ band.

Biomass‐Derived Transparent Bamboo Composite Films with Europium‐Based Photoconversion for Energy‐Efficient Smart Agriculture

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A biomass‐based transparent bamboo composite doped with europium efficiently converts UV light into photosynthetically active red light, significantly enhancing plant growth and providing a sustainable alternative to petroleum‐based agricultural films. The rational design of sustainable light‐conversion agricultural materials is critical for enhancing ...

Chlorophyll a + b Content and Chlorophyll Fluorescence in Avocado

Journal of Agricultural Science, 2012
Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m -2 in TxS240 to 4320 mg m -2 in Simmonds.

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

Food Frontiers, EarlyView.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Fluorescent light and sunlight radiations may improve rice bran oil colour and influence its oxidative stability and chemical composition

Food Biomacromolecules, EarlyView.
Abstract The influence of pretreatment of rice bran oil using fluorescent and sunlight radiations on its colour and their influence on its chemical composition and oxidative stability were assessed. Rice bran oil was stored under sunlight, fluorescent light and ambient conditions for 60 days. Oil samples were collected every 15 days for analysis.

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, EarlyView.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Application of chlorophyll fluorescence in fruit science [PDF]

1st PhotosynthOS Conference - Book of abstracts, 2023
The wide range of research on chlorophyll fluorescence (ChlF) demonstrates its usefulness in many plant biology, agronomy, and ecology research areas. Perennial fruit trees are frequently exposed to various biotic and abiotic stresses throughout their lifespan, limiting their crop quality and yield.
