Micropropagation of Actinidia chinensis : Effects of Growth Regulators on Proliferation Rate

The in vitro culture of Actinidia chinensis has been widely studied (Harada, 1975; Bini, 1979; Hirsch et al., 1979; Quoirin et al., 1979 ; Standardi, 1981, 1982, 1983) and several commercial laboratories use micropropagation for a large scale production. However, the different behaviour of cultivars in in vitro culture has not been thoroughly tested. The aim of our research was to investigate the response of different cultivars to increasing BAP concentrations in the growing medium during the proliferation phase and to evaluate the carryover effects of BAP on subsequent rooting of propagules
