Abstract In this study, the effect of exogenous application
of gibberellic acid (GA3) and the presence of both leaves and
petioles on sprouting of the rosetting plantlets of GF677 (peach x almond
hybrid) was examined. GA3 caused a significant increase in sprouting
of rosetting plantlets at application rates of 12.5 and 50 mg litre-1.
The results showed that rosetting plantlets without leaves and petioles,
or with only one petiole, sprouted significantly better compared with those
with one-quarter of leaf, all petioles, or all petioles and leaves. In addition,
Mg + Zn + B (trace) in Murashige & Skoog medium significantly increased
the fresh weight and water content of plantlets.
