✦ Synopsis

Shoots which proliferated from shoot tip explants of 'Colorado White Simm' carnation and 'Fantastic' tomato on MS medium containing 5mgl -~ benzyladenine were rooted and grown in vitro as mieroplants. Tomato microplants grown in medium with 5 gl -~ sucrose had less overall shoot and root growth than those with 10, 20, or 30g1-1 sucrose regardless of NAA level. Carnation shoot growth was reduced by 5 g 1-1 sucrose but root growth was not affected except when no sucrose was supplied. Microplant height and rooting of carnation were maximal when grown in 20g 1-1 sucrose whereas tomato microplant growth was greatest with 30g1-1 sucrose. Microplants of both species had reduced height and root growth when the MS nutrient salts were lowered to 25%, 50%, or 75% compared to full strength when sucrose was supplied at 5gl -~ .
