For phototropism, the … WebDec 16, 2006 · According to the Cholodny–Went hypothesis, gravitropic differential growth is brought about by the redistribution of auxin (indolyl-3-acetic acid, IAA). We reinvestigated the relevance of different auxins and studied the role of ethylene in hypocotyls of sunflower and shoots and roots of rye and maize seedlings.

WebJul 1, 1987 · Abstract The existence of different auxin sensitivities in epidermal and subepidermal tissues (KV Thimann, CL Schneider 1938 Plant Physiol 25: 627-641) suggests a refinement to the Cholodny-Went theory which overcomes some of the difficulties associated with it. WebRecent data support the basics of the Cholodny-Went hypothesis, indicating that differential growth is due to redistribution of auxin to the lower sides of gravistimulated … river city steak house

They proposed that gravitropic curvature was dependent upon lateral transport of the plant hormone indole-3-acetic acid — auxin — from the upper to the lower side of a … The Cholodny–Went model for the phototropic movement of shoots was later extended to gravitropism of roots, where auxin was thought to inhibit rather than stimulate growth and to accumulate in the lower side of a root section, causing the root to bend downward. See more In botany, the Cholodny–Went model, proposed in 1927, is an early model describing tropism in emerging shoots of monocotyledons, including the tendencies for the shoot to grow towards the light (phototropism) … See more The model was independently proposed by the Russian scientist Nikolai Cholodny of the University of Kyiv in 1927 and by Frits Warmolt Went of … See more Evidence that supports Cholodny–Went over competing theories was reported by Iino and Briggs in 1984, showing that there was decreased growth on the lighted side of a corn coleoptile and increased growth of the shaded side.
