Excerpt: ... to designate the exudation of liquid water under pressure from injured regions of plants such as may take place when stems, roots, or branches are injured from wounds by cutting, boring holes, mechanical injury, or other means. II. REVIEW OF LITERATURE ON BLEEDING PHENOMENA The phenomena of bleeding, because it is so easily observed, in maple, grapeTvine, and birch, has been studied for several centuries. John Ray (46) was the first to observe the phenomenon while Hales (23) made a more extensive study of it. Ray and Hales observed bleeding in trees and vines only, while Hofmeister (25) showed that bleeding was possible from herbaceous plants as well. He also was the first to show that bleeding is possible in summer when transpiration is prevented. These investigators as well as Dutrochet (15) and Dassen (12) considered the active exudation of water to be due to the pressure caused by the absorptive activities of the roots and positive results were first obtained with root stocks and with single roots or even with root apices. Brttcke (7) was the first to show that the bleeding in spring gradually decreased with the opening of the leaves, hence showing the relation of the turgid cells to leaf growth. He also found that there was considerable difference in pressure at different heights in a grape vine. For example, a manometer placed fifteen feet from the base of a vine would show less pressure than one placed five feet from the base. Hofmeister (25) repeated Brticke's work and also experimented with various herbaceous plants. He showed that the same phenomena may be observed in any given plant even in small anfUials which form little wood. By cutting off such plants as Ricinus, Tobacco, Digitalis, Nettle, Sunflower, Maize, and other cultivated plants when ...
