TL;DR: Chlorophyll fluorescence parameters based on the lake model q(L), phi (NPQ) and phi(NO) have been found more appropriate for estimating the fraction of open centres, the quantum yield of regulated energy dissipation in photosystem II (PSII) and the Quantum yield of non-regulated energy dissolution in PSII, respectively.

TL;DR: In this article, the effect of two nutrient solution temperatures (cold (10°C) and warm (22°C)) during two flowering events of rose plants ( Rosa Â× hybrida cv. Grand Gala) were examined by measuring chlorophyll (Chl) a fluorescence, ammonium (NH 4 + ) content and nitrate reductase (NR) activity in four different leaf types, that is, external and internal leaves of bent shoots and lower and upper leaves of flowering stems.

TL;DR: The higher fruit found when rootstock genotype was homozygote for SpHKT1 supports the thesis that scion HKT1 is loading Na+ into the phloem sap in leaves and unloading it in sink organs, and grafting desirable crop varieties on stress-tolerant rootstocks tenders an opportunity to increase both salt tolerance and quality.

TL;DR: This work found out how the photosynthetic light reaction, measured by chlorophyll a fluorescence in internal and external leaves of arched shoot could be modulated by light changes, and measured nitrate reductase activity, NH4+, sucrose and starch levels.

TL;DR: Results related to Chl a fluorescence, indicate that pruned plants have a higher capacity for better promoting the photosynthetic light reaction than non-pruned plants.
