Abstract

Excised vegetative buds of Rhododendron cv. Pink Pearl, present in the axils of the bud scales, required light for sprouting, but no special daylength was necessary to break dormancy. Glucose greatly enhanced sprouting, but was not essential. Glucose could not replace light, but light could partly replace glucose for inciting sprouting. Only fully developed buds were capable of sprouting. Temperature played a decisive role, 21-25 deg C being the optimum range. Macroelements were not essential, but sprouting on a medium without macroelements was reduced. It was impossible to induce adventitious root formation on excised shoots grown on a medium containing IBA. (Abstract retrieved from CAB Abstracts by CABI’s permission)
