Carob tree growth stimulated with gibberellin —salable nursery plants produced in less time

SLOW stem elongation and the excessive time required for production of a salable plant have been problems with a number of nursery plants including the carob tree (Ceratonia siliqua). Aqueous spray applications of potassium gibberel-late concentrations made at specific intervals, over a 20-week-treatment period, offer the possibility of producing salable plants more rapidly than would be possible under ordinary nursery management practices.
