Effect of calcium on root development and root ion fluxes in salinised barley seedlings.

The effects of various Na / Ca ratios on root growth, development, and ion acquisition patterns were studied in hydroponic experiments with barley (Hordeum vulgare L.) plants. In total, interactions between three different levels of salinity (1, 50 and 100 mM NaCl) and three different levels of Ca (0.

Epidermal cell division and cell elongation in two Aegilops species with contrasting leaf elongation rates.

The 2-fold difference in final length of leaf number three on the main stem between the fast-growing Aegilops tauschii L. and the slow-growing Aegilops caudata L. is correlated with a difference in leaf elongation rate (LER), and not in duration of leaf elongation.
