Die Wasseraufnahme der höheren Pflanzen gemäßigter Klimate durch oberirdische Organe

Dew as an Ecological Factor: I. A Review of the Literature

“…Apparently dew absorbed during the night by these plants balances the small transpirational loss that occurs during a winter day. Wetzel ( 1924) investigated the water absorbing ability of leaves from over 100 species native to the temperate region. Most of the leaves were able to absorb water, and the cuticle, however, strongly developed, was generally not an insuperable barrier to the passage of water.…”

Kritische Untersuchungen zur Wanderung von Fluorochromen in Blättern

“…Jodessigs~iure: 10 -~ und 10 -5 tool/l; 1 und 5 rain. Butylurethan: 0,5,0,2,0,1,0, 0,65, 0,13, 0,013, 0,0013 tool/l; l, 5 und 10 rain. . Athylenchlorhydrin: 0,62,0,12,0,012,0,0012 tool/l;1,5 und e) Aminopyrentrisulfosaures-Na 1 : 1000 wird der Blattfli~ehe geboten, vom Stiel her wird Leitungswasser zugefiihrt.…”

Sap Hydraulics

“…The simple physical nature of the problem is further brought out by the experiments on reverse flow and absorption by leaves performed by numerous investigators, including HAEs (41), DANDENO (30), WETZEL (108), ARNDT (1), and HARVEY (43). The application of hydraulics is further developed by the correlation of movement through the vessels with PoIsEuuLE's (48) formula for capillary tubes made by EWART (37), and the even closer correlation between rate of flow and vessel diameter for different sizes of vessels made by FURR (39).…”
