Cytological studies of early stages of powdery mildew in barley and wheat. V. Effects of calcium on the infection of coleoptiles of barley by Erysiphe graminis hordei


, : Cytological studies of early stages of powdery mildew in barley and wheat. V. Effects of calcium on the infection of coleoptiles of barley by Erysiphe graminis hordei. Canadian Journal of Botany 56(20): 2544-2549

CaCl2 enhanced the incidence of haustoria but depressed that of papillae. CaBr2 and Ca(NO3)2 likewise enhanced the incidence of haustoria.

Some effects of Ca salts on the infection process of E. graminis hordei in coleoptiles of barley [Hordeum vulgare cv. Kobinkatagi] were investigated.

Antagonistic effects of calcium and lithium on the infection of coleoptiles of barley by Erysiphe graminis hordei. In growth chamber studies, whereas 1 mM lithium chloride inhibited appressorial formation by E. graminis f. sp. hordei considerably and haustorial formation completely, these effects were totally offset by 10 mM calcium chloride. Moreover whereas...

The susceptibility of barley to infection by E. graminis hordei is enhanced by Ca ions but inhibited by Li. Some effects of Ca and Li ions on the infection process of E. graminis hordei in coleoptiles of barley were investigated. Whereas 1 mM LiCl...

Haloes were successfully detected by various dyes when the inoculated coleoptiles were treated with 70% ethanol at 80 degrees C for 30 min before staining. Responses of haloes on coleoptiles to basic and acid dyes were very similar to those on bar...
