| Abstract:
Shoots of 3 cvs (Snack 616, Clementina and 234) of Gerbera Jamesonii Hybrida, grown "in vitro", were histologically analysed to determine time and mode of formation of root primordia. The ability of these microcuttings to directly form roots in the acclimatization greenhouse was also verified. While root initials were already visible "in vitro" on the 21st day of multiplication, the rooting potential could be expressed in the greenhouse, after only 7 days, in a perlite-peat substrate. This early rhizogenesis occurs in 20% of the tested explants, 100% rooting can be obtained by elongating the time in both the multiplication phase and in the greenhouse. | |
