Plant Growth Regulators Enhance Floral Induction of ‘Ziniangxi’ Litchi Under Warm–Humid Winters

Horticulturae
Floral induction in late-maturing litchi is vulnerable to warm, humid winters with insufficient chilling. The late cultivar ‘Ziniangxi’ was evaluated during January–February 2024 in an experimental orchard in Hainan, China, when chilling accumulation was

The extent of trees in the tropics

, 2022
Abstract Remote sensing-based assessments of tree cover and extent provide insight into global and local land use planning. However, there remains considerable uncertainty about the extent of drylands forests and trees in areas with non-forest land use. Here, we present a 10-meter tree extent map for 4.35 billion hectares in the tropics (-23.44°

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.
