Oxidative stress responses and root lignification induced by Fe deficiency conditions in pear and quince genotypes.

Tree physiology - 1 Jan 2011

Donnini Silvia, Dell'Orto Marta, Zocchi Graziano

Abstract excerpt

We analysed Pyrus communis cv. Conference and Cydonia oblonga BA29, differently tolerant to lime-induced chlorosis, to identify the key mechanisms involved in their different performance under Fe deficiency induced by the absence of Fe (-Fe) or by the presence of bicarbonate (+FeBic). Under our experimental conditions, a decrease in root elongation was observed in BA29 under bicarbonate supply. Superoxide...
