Photophysiology of turion germination in Spirodela polyrhiza (L.) Schleiden VIII. Calcium dependence and β-amylase activity

Abstract

Red-light-induced germination (via phytochrome) of turions of Spirodela polyrhiza (L.) Schleiden, strain SJ, showed an absolute requirement for exogenously applied calcium (Appenroth et al. 1990b, Biochem. Physiol. Pflanzen 186, 209–219). With calcium step-up experiments (from 0.9 μM to 1 mM Ca2+) the influence of Ca2+ on the escape from far-red-light… (More)
