Multibump solutions to possibly degenerate equilibria of almost periodic Lagrangian systems
(Springer Verlag (Germany), 1999)
We study via variational methods some chaotic features of a class of almost periodic Lagrangian systems on a torus. In particular we show that slowly oscillating perturbations of such systems admit a multibump dynamics ...
Iron reduction in iron-stressed plants of Actinidia deliciosa genotypes: Involvement of PM Fe(III)-chelate reductase and H+-ATPase activity
Micropropagated plantlets of the Actinidia rootstock D1, resistant to lime-induced iron (Fe) deficiency, and the Actinidia deliciosa line 2084 (sel. 2084), moderately sensitive to Fe starvation, were grown in nutrient ...
Water-extractable humic substances enhance iron deficiency responses by Fe-deficient cucumber plants
The ability of Fe-deficient cucumber plants to use iron complexed to a water-extractable humic substances fraction (WEHS), was investigated. Seven-day-old Fe-deficient plants were transferred to a nutrient solution ...
