Efficiency In Thin-Film Liquid System For Hosta Micropropagation, Jeffrey Adelberg
Jeffrey W Adelberg
Three varieties of Hosta (‘Striptease’, ‘Minuteman’ and ‘Stiletto’) at four densities (40, 80, 120 and 200 explants per litre) were micropropagated on semi-solid agar and a thin-film liquid system with intermittent wetting of plant tissue. The mechanics of wetting by a small wave front required a larger rectangular vessel (11 × 27=297 cm 2) compared to the common cylindrical baby food jar (18 cm 2). Plants multiplied more rapidly in the agitated thin-film system than on agar. Lower plant densities increased rates of multiplication in liquid, but had little or no effect on multiplication rate on agar. Increasing plant density …
