- 环境科学 环境科学
- 城市生态城市生态学
背景情况:
- 开采的沙子和是城市常见的种植基质,但它们的使用与可持续发展目标相冲突.
- 建筑垃圾是一个易于获得的替代品,尽管其性和密度对植物生长构成挑战.
研究的目的:
- 调查建筑垃圾的潜力,用松树皮修改为城市种植的基材.
- 评估这些新型基质的物理和化学特性及其对植物生长的影响.
主要方法:
- 通过使用四种矿物成分 (,回收砂,碎混凝土,回收岩石) 和三种松树皮体积 (10%,20%,50%v/v) 创建了12个基板.
- 评估了物理和化学特性.
- 在一个容器实验中测试了8种基板,其中包括2种木质灌木,Alyogyne huegelii和Goodenia ovata.
主要成果:
- 矿物成分具有高度性 (pH9.2-12.3),压碎的混凝土仍然具有高性.
- 增加松树皮改善了充满空气的多孔性,但减少了水的保留.
- 植物生物质在不同的矿物成分中是可比的,但基质含量较低,松树皮占50%.
结论:
- 用松树皮修改的建筑垃圾可以成功地支持城市种植地的木质灌木生长.
- 这种方法与可持续发展目标一致,通过促进资源循环利用和废物再利用在城市绿化中.

Recycling Endosomes and Transcytosis
3.6K
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

Plant Hormones
27.7K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Tonicity in Plants
60.0K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.

Plant Cell Wall
60.7K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Plant Cells and Tissues
65.9K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.
