| Abstract/Contents: | "Four cultivars of ryegrass (Lolium multiflorum Lam. cvs. Gulf, Marshall, Urbana, and Wilo) were grown in nutrient solution (pH 4.2) at two Al levels (0 and 74 uM). Cations were desorbed from the Donnan free space of roots of 15-, 23-, and 35-day old plants using BaCl2, BaCl2-triethanolamine, NH4OAc, and KCl. The amounts of desorbed Ca2+ and K+ decreased, while desorption of Mn2+ and Na+ increased with plant age. Differences between 15- and 35- day old plants, but not between 15- and 23-day old, were significant. Aluminum considerably decreased the amount of desorbed divalent cations (Ca2+ and Mg2+) and increased the amount of desorbed K+ and Na+. Ability to resist these changes appeared to be one of the mechanisms determining Al tolerance of ryegrass cultivars." |
