Abstract
Adventitious shoot formation from leaf explants of carnation (Dianthus caryophyllus L.) was investigated. The two leaves from one node of in vitro-grown plants showed different shoot-forming potential, depending on the order in which the leaves were removed from the stem. The leaf removed second formed more shoots and also had a large amount of adhering stem tissue. Explants with equal amounts of adhering stem tissue were obtained by making two incisions through the fused leaf bases, prior to their removal, resulting in an improved shoot formation. The procedure developed for leaf explants from in vitro-grown plants was also applied to leaf explants from greenhousegrown plants. Shoot formation from leaf explants taken from greenhouse-grown plants was further improved by cutting the leaf explant longitudinally into two parts.
