Bioscience, Biotechnology, and Biochemistry, 2022 ABSTRACT Shade cultivation of tea plants (Camellia sinensis L.) is employed for the production of high-quality green tea which increases the content of chlorophylls and free amino acids, including theanine. However, shaded tea plants suffer from photooxidative stress caused by sudden exposure to high light (HL) when the shade is removed.

Frontiers in Plant Science, 2022 Shading is one of the most chronic restrains which can lead to the lodging of intercropped plants. In order to increase the soybean stem lodging resistance, a 2-year field trial was conducted to evaluate the impact of different ratios and concentrations ...

Stress Responses of Shade-Treated Tea Leaves to High Light Exposure after Removal of Shading
Plants, 2020 High-quality green tea is produced from buds and young leaves grown by the covering-culture method, which employs shading treatment for tea plants (Camellia sinensis L.). Shading treatment improves the quality of tea, but shaded tea plants undergo sudden exposures to high light (HL) at the end of the treatment by shade removal.

Assessing shade stress in leaves of turf-type tall fescue (Festuca arundinacea Schreb.)
Photosynthetica, 2021 Shade treatment was applied to tall fescue with 30% full light. The results showed that shade increased chlorophyll (Chl) content per unit leaf mass, decreased the Chl a/b ratio in the mature leaves, and decreased effective quantum yield based on Chl ...

Impact of shading on evapotranspiration and water stress of urban trees
Ecohydrology, 2023 AbstractEvapotranspiration of urban street trees is essential in mitigating urban heat islands due to its cooling effect. However, current shifts in rainfall and temperature regimes towards drier and hotter periods in Central Europe have caused substantial water stress for street trees.

The American Naturalist, 2009 The interacting effects of different environmental cues in determining a plant's phenotype and performance are poorly understood aspects of phenotypic plasticity. We examined the interacting effects of shading and mechanical stress (MS) on growth, reproduction, and mechanical stability.

Risk stratification by stress echocardiography: a whiter shade of pale? [PDF]
European Journal of Echocardiography, 2004 Please see page 205 for the article by Moreno et al. (doi: 10.1016/j.euje.2003.11.008) to which this editorial pertains. In this issue of the Journal, Moreno et al. show the high negative predictive value of a negative dipyridamole stress echocardiogram in medically stabilized unstable angina.1 The negative predictive value was, however, lower in ...

Seedling growth and photosynthetic response of Pterocarpus indicus L. to shading stress
Plant Signaling & Behavior, 2023 In tropical forests, the shade provided by tree canopies and extreme climate causes inhibition of plant seedling growth due to the lack of light. However, the plants can acclimate to such environmental stress by generating specific responses. The present study aimed to investigate the effects of shading conditions on ecophysiological performance of ...

Non-linear effects of drought under shade: reconciling physiological and ecological models in plant communities [PDF]
, 2011 The combined effects of shade and drought on plant performance and the implications for species interactions are highly debated in plant ecology. Empirical evidence for positive and negative effects of shade on the performance of plants under dry ...

Heat Stress Interaction with Shade and Cooling
Journal of Dairy Science, 1994 Hot weather causes heat stress in dairy cattle. Although effects are more severe in hot climates, dairy cattle in areas with relatively moderate climates also are exposed to periods of heat stress. The resultant decrease in milk production and reproductive efficiency can be offset by implementation of a program consisting of cooling through shades ...
