Mapping QTLs for chlorophyll content and chlorophyll fluorescence in wheat under heat stress

open access: yesBiologia Plantarum, 2018
Heat stress, one of the major abiotic stresses in wheat, affects chlorophyll fluorescence and chlorophyll content and thereby photosynthesis. To identify quantitative trait loci (QTLs) associated with these traits under terminal heat stress, 251 ...

Responses of tomato (Solanum lycopersicum L.) plants to iron deficiency in the root zone [PDF]

open access: yes, 2019
Iron deficiency induces a yellowing in the aerial part of plants, known as iron chlorosis, and reduces the growth, yield, and quality of the fruits. Understanding plant response to iron deficiency is essential for agronomic management. This study decoded

Soybean leaf nitrogen, chlorophyll content, and chlorophyll a/b ratio

open access: yesPhotosynthetica, 2007
The objective of this study was to assess genotypic variation in soybean chlorophyll (Chl) content and composition, and to test if these data could be used as a rapid screening method to predict genotypic variation in leaf tissue N content. Chl contents and composition were examined among 833 soybean (Glycine max L.
