Chlorophyll fluorescence of the testa of Brassica oleracea seeds as an indicator of seed maturity and seed quality

Scientia Agricola, 1998
Chlorophyll fluorescence of the testa of seeds is proposed as a non-invasive method for the determination of maturity and quality of seeds. In this study cabbage seeds (Brassica oleracea) were sorted individually based on the chlorophyll fluorescence ...

Impacts of Chlorine on the Change of Chlorophyll Fluorescence Spectrum to Phaeodactylum tricornutum

Analytica, 2023
Chlorine-containing disinfectants have been widely used all over the world to prevent COVID-19. However, little is known about the potential risk of chlorine-containing disinfectants in the marine environment. Phaeodactylum tricornutum (P.

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.

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

Advanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

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.

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.

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice

Advanced Science, EarlyView.
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.
