HARDENING AND IN VIVO ESTABLISHMENT OF MICROPROPAGATED GREVILLEA AND LEUCOSPERMUM

Studies were carried out to determine the optimal developmental stage of in vitro propagated Grevillea ‘Roundo’ and Leucospermum cordifolium for transplanting to outdoor conditions.
In addition suitable environmental conditions were evaluated.

Longer plantlets with three to five nodes survived better than short ones.
Under fog conditions a higher percentage of in vitro rooted plants became established than unrooted shoots but under mist the opposite results were observed in Grevillea ‘Roundo’.
