Figure 1. Plants in cellular trays and pots (original)Vegetative propagation by cuttingsCuttings were made from plants grown in thegreenhouse of the Botanical Garden 'AlexandruBorza' Cluj-Napoca from the seeds of the threehybrids studied. Leaves were removed fromcuttings length exempting those in the apicalzone (Figure 2).Cuttings were trimmed to the size of abouteight cm and planted in wooden boxes ondifferent rooting substrates.For rooting of cuttings were used three types ofsubstrate:-S1-sand river; -S2-peat + sand,mixture of 1:1 and; -S3-peat + sand + gardensoil, mixture of 1:1:1.After 40 days there have been observations onrooting percentage. In vivo plants were grownand maintained in the greenhouse of theUSAMV Cluj-Napoca and served to multiplyby cuttings and in vitro propagation.305
