When the tree begins its life, it is mostly leaf in mass (Fig. 7.1a). As a tree grows in stature, it becomes mostly stem in mass and the foliage represents only a few percent of the total mass. Roots remain relatively constant at about one-fifth the total mass as a tree grows ...
Structure and physiology of Sitka spruce roots Growth and development of Sitka spruce roots is reviewed in relation to tree stability. Two features make Sitka spruce liable to windthrow on upland sites:... MP Coutts,JJ Philipson - 《Proceedings of the Royal Society of Edinburgh B》 被引量: ...
In many ways,many of us are like those giant Sequoias,so proud,so bit,so strong,withstanding wind and fire,yet not allowing our roots to seek deep into life's meaning.Many people have only shallow roots in soft ground,leaving them constantly on the edge of falling over to their destructi...

Under a Creative Commons license open accessHighlights Abstract Warming temperatures and droughts are driving widespread forest dieback and growth decline worldwide. In forests experiencing dieback, declining trees may exhibit altered climate memory of growth, indicative of physiological impairment. Thus, we...
Tree traits, by definition, refer to the characteristics of trees, such as their crown shapes, leaves, and roots. From the analyzed studies, factors that influence the cooling effects of trees include tree species (TS), tree morphology (TM), LAI and LAD (LD), leaf morphology (LM), and ...
This is made possible because many legumes have special structures on their roots called nodules, which house special bacteria that can convert nitrogen from the air into nitrates that the plant can use. This adaptation enables legumes to thrive in poor soils. In many regions, crop rotation has...
