Effects of Ca++ on plant sensitivity to high NaCl concentrations
SummaryNaCl reduced growth ofHordeum vulgare much more at low than at high nutrient, due solely to the Ca++-status of the medium.
Counteraction of NaCl with CaCl2 or KCl on pigment, saccharide and mineral contents in wheat
NaCl salinity affected growth, the contents of chlorophyll, carotenoids, saccharides and some minerals (Na, K, Ca, Mg, P) in wheat (Triticum vulgaris L.) plants. Irrigation of soil with CaCl2 or KCl greatly ameliorated the adverse effects of NaCl salinity. This counteraction was associated with an increase in contents of saccharides, proteins and Ca, Mg and P which might explain their role in osmotic adjustment.
Stability results for the solutions of some third and fourth order differential equations
SummaryThe paper investigates conditions under which solutions of the equations (1) and (2) of § 1.1 tend to zero as t → ∞.
