Community Shade Tree Leaves: Beneficial Uses for Agriculture
HortTechnology, 2022 Every autumn an abundance of leaves from various species of shade trees [e.g., oak (Quercus sp.), maple (Acer sp.)] are collected from urban landscapes. In 1988, shade tree leaves were banned from landfills and combustion facilities in New Jersey because

Photosynthetic responses of sun- and shade-grown barley leaves to high light: is the lower PSII connectivity in shade leaves associated with protection against excess of light? [PDF]
Photosynthesis Research, 2014 In this study, we have compared photosynthetic performance of barley leaves (Hordeum vulgare L.) grown under sun and shade light regimes during their entire growth period, under field conditions. Analyses were based on measurements of both slow and fast chlorophyll (Chl) a fluorescence kinetics, gas exchange, pigment composition; and of light incident ...

Analysis of the Metabolic and Structural Changes in Ulmus pumila ‘Zhonghua Jinye’ Leaf Under Shade Stress [PDF]
PlantsUlmus pumila L. ‘Zhonghua Jinye’ is a plant variety with colourful leaves that is widely used in landscaping. In our study, the leaves of U. pumila ‘Zhonghua Jinye’ fade and turn green under light (LT, 45%), moderate (MD, 70%) and high (HG, 95%) shading ...

Mechanism Underlying the Shading-Induced Chlorophyll Accumulation in Tea Leaves [PDF]
Frontiers in Plant Science, 2021 Besides aroma and taste, the color of dry tea leaves, tea infusion, and infused tea leaves is also an important index for tea quality. Shading can significantly increase the chlorophyll content of tea leaves, leading to enhanced tea leaf coloration. However, the underlying regulatory mechanism remains unclear.

More Manganese Accumulates in Maple Sun Leaves than in Shade Leaves [PDF]
Plant Physiology, 1989 Nuclear magnetic resonance and neutron activation analysis were used to measure manganese concentrations in leaves of Acer platanoides. Mn was found to accumulate in both the vacuoles and the chloroplasts, with more Mn (per unit area) in sun leaves than in shade leaves. No Mn was lost at senescence.

Mechanism underlying the carotenoid accumulation in shaded tea leaves
Food Chemistry: X, 2022 Carotenoids contribute to tea leaf coloration and are the precursors of important aromatic compounds. Shading can promote the accumulation of carotenoids in tea leaves, but the underlying mechanism remains unknown. In the study, we analyzed the content and composition of carotenoids, and transcript levels and functions of related genes in carotenoid ...

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 ...
