Investigation on morphological, photosynthetic traits, and arbuscular mycorrhizal fungi (AMF) roots infection in sago palm (Metroxylon sagu rottb.) under saline condition

Horticultural Science
This study investigated the response of sago palms to saline conditions, focusing on their morphological and photosynthetic performance. The photosynthetic traits were evaluated using OJIP chlorophyll fluorescence transient.

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 ...

Estimation of Corn Canopy Chlorophyll Content Using Derivative Spectra in the O2–A Absorption Band

Frontiers in Plant Science, 2019
Chlorophyll (Chl) is one of the most important classes of light-absorbing pigments in photosynthesis, and the proportion of Chl in leaves is closely related to vegetation nutrient status.

Seasonal biases in fluorescence-estimated chlorophyll-a derived from biogeochemical profiling floats

Communications Earth & Environment
Marine phytoplankton biomass and chlorophyll-a concentration are often estimated from pigment fluorescence measurements, which have become routine despite known variability in the fluorescent response for a given amount of chlorophyll-a. Here, we present
