Abstract
Effects of free-draining, non-draining and hydroponic tank culture on ex vitro establishment and quality of micropropagated microcuttings of the ornamental aquarium plant Cryptocoryne wendtii De Wit. were examined. After 16 weeks microcutting survival and shoot production was similar between treatments. Plants cultured hydroponically in either non-draining flats or tanks exhibited significantly greater leaf production and elongation than those grown in free-draining plugs. Root production and elongation were significantly reduced in free-draining plugs, presumably due to increased water stress. Plantlet growth and quality was increased when microcuttings were maintained in truly hydroponic systems. This presumably resulted from reduced water stress.
