TL;DR: The SPAD-502 has been shown to be a good tool to diagnose the integrity of the photosynthetic system in coffee leaves, and can thus help in the advanced interpretations of the photochemical process of these plants.

TL;DR: The results suggest that the defence system of grape leaf tissues against UV-B is activated byUV-B irradiation with ABA acting downstream in the signalling pathway, as assessed by ion leakage.

TL;DR: Analysis of the damage caused in photochemical efficiency of photosynthesis under salinity conditions in these cultivars revealed no correlation between the levels of SALT protein expression and sensitivity to the stress, indicating that the expression of Salt protein is not restricted to responses to environmental stresses and that high levels of expression do not confer tolerance to salinity.

TL;DR: In this article, the authors evaluated the greenhouse acclimatization of 'Vitoria' pineapple propagated by plant tissue culture in response to different doses of humic acids isolated from vermicompost and filter cake.

TL;DR: The defense mechanisms triggered by + UV-B reduced lipid peroxidation, but they were insufficient to protect the photosynthetic pigments per leaf dry weight basis, and the +UV-B effects depend on tissues developmental stage and interplay with other environmental conditions such as total radiation and air temperatures.
