. How crops grow. A treatise on the chemical composition, structure and life of the plant, for students of agriculture ... Agricultural chemistry; Growth (Plants). MOTION OF THE JUICES. 381. Fig, 6& for growth, as in moist, warm air, with its lower extremity in water, roots form chiefly at the edge of the bark just aboye the removed ring. The twisting, or hiilf-breaking, as well as ringing of a layer, promotes the development of roots. Latent buds are often called forth on the stems of fruit trees, and branches grow more vigorously, by making a transverse incision through the bark just below the point of their issue. Girdling a fruit-bearing branch of the grape-vine near its junction with the older wood has the effect of greatly enlarging the fruit. It is well known that a wide wound made on the stem of a tree heals up by the formation of new wood, and commonly the growth is most rapid and abundant above the cut. From these facts it was concluded that sap descends in the bark, and, not being able to pass below a wound, leads to the organization of new roots or wood just above it. The accompanying iUustration, Fig. 66, represents the base of a cut- ting from an exogenous stem (pear or curtant), girdled at JB and kept for some days immersed in water to the depth Indicated by the line Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Johnson, Samuel William, 1830-1909.
