The objective of this study was to determine the effect of sucrose concentrations (2 and 3%) added to nutritive culture medium over growing parameters: plantlets length, number of leaves/plantlets, root length, fresh plantlet weight, fresh root weight. The experience is bifactorial (2 x 3), on 3 repetitions, with next factors: experimental factor A - the sucrose concentration on nutrient medium with two graduations (2, as control and 3%) and experimental factor B: variety, with 3 graduations (Marvis, considered as control, Castrum and Ervant). The use of 3% sucrose concentration has a positive influence in vitro, for leaves number, fresh plantlet weight and fresh root weight. Castrum variety has a significant positive and a distinctly significant positive differences (1.69 cm and 3.44 cm) for the length of the plantlets, respectively the number of leaves/plantlets. Also, Ervant variety had a good in vitro behaviour with a distinctly significant positive (2.50 cm) and significant positive differences (2.11 leaves and 0.052 g) for three of the analysed parameters (plantlet length, number of leaves/plantlet and fresh plantlet weight).
