Moderate photoinhibition of photosystem II protects photosystem I from photodamage at chilling stress in tobacco leaves

Frontiers in Plant Science, 2016
It has been indicated that photosystem I (PSI) is susceptible to chilling-light stress in tobacco leaves, but the effect of growth light intensity on chilling-induced PSI photoinhibition in tobacco is unclear.

Differences in leaf area, trichome density, and xylem structure between the two types of Theobroma cacao l. cultivation: With or without shade plants

International Journal of Plant Biology, 2020
This study aimed to analyze the structure and density of non-glandular trichomes and the area of cocoa leaves, and the differences of xylem vessel structures on various shade tree composition. The leaf area and length, and trichomes were observed.

UV-A induced fluorescence images in sun and shade leaves [PDF]

BMC Plant Biology, 2005
Background At their natural environment plants are exposed to high fluxes of photosynthetically active and UV radiation. The increased synthesis of UV-absorbing compounds, such as flavonoids and other polyphenols, are accepted as a plant response to increased UV radiation.

Does selective logging affect the leaf structure of a late successional species?

Rodriguésia
The anatomical characteristics of both sun and shade leaves of Alseis pickelii were investigated in order to evaluate the consequences of selective logging (in seasonally dry Atlantic Forest) on the leaf structure of this species.

From Chloroplast Biogenesis to Chlorophyll Accumulation: The Interplay of Light and Hormones on Gene Expression in Camellia sinensis cv. Shuchazao Leaves

Frontiers in Plant Science, 2020
Chloroplast development and chlorophyll metabolism have been well described in model plants but not in perennial woody crops. Of particular interest is the interplay between light and hormones under shade conditions.

Recovery kinetics of winter stressed conifers: The effects of growth light environment, extent of the season, and species. [PDF]

, 2010
Evergreens undergo a dramatic reduction in their maximal photochemical efficiency (measured as Fv/Fm) during winter, which is largely due to increases in a sustained form of thermal energy dissipation.
