The limits to tree height
Splet28. jul. 2000 · A tree naturally works to avoid this. It does so in two ways: 1) by producing smaller leaves in the crown that have fewer water-releasing pores, called stomata, and 2) by closing its stomata. This slows the flow of sap, reducing the risk of embolism. Stomata-closing, however, is the beginning of the chain of events that limits tree growth. SpletThe height to which trees can grow and the biophysical determinants of maximum height are poorly understood. Some models predict heights of up to 120 m in the absence of …
