【 摘 要 】

Effect of the growth regulators Atonik, Rastim 30 DKV, Stimulator AS 1, and Stimulax III on rooting of half-woody shoots of the species Karwinskia humboldtiana (Roem et Schut) Zucc. and Karwinskia parvifolia Rose was studied. Rooting does not occur without stimulation in these species, after stimulation rhizogenesis takes 14 to 16 weeks. Growth regulators, with the exception of the preparation Atonik, showed a significantly stimulating effect on rhizogenesis, and effect of them declined in the order Stimulax III, Stimulator AS, and Rastim 30 DKV. The percentage of rooting in the species Karwinskia humboldtiana was higher than that in Karwinskia parvifolia and this was dependent on the age of the plants, the type of stimulator, cutting, substrate, and conditions of cultivation.
