Pruning Responses of Tissue-Cultured Plantlets of Rhododendrons
Keyword(s):
Abstract Plantlets of Rhododendron ‘Molly Ann’, R. ‘Paprika Spiced’, and R. ‘Travis L.’, recently rooted from tissue culture, were grown in a greenhouse in individual containers. Plants pruned by pinching, top-pruning, or root-pruning were compared to unpruned plants. Growth, as measured by shoot height, shoot dry weight, root dry weight, and stem caliper, was generally reduced by pruning. Top-pruning and pinching induced branching in all cultivars tested and improved stem taper (ratio of basal to upper caliper) in two cultivars, including R ‘Travis L.’, which is particularly prone to develop weak stems when produced by tissue culture.
