DONATO, Virgínia M.T. Sabino; ANDRADE, Arnóbio Gonçalves de  e  CAMARA, Terezinha Rangel. Sugarcane varieties cultivated in vitro with different nitrogen sources. Sci. agric. [online]. 1999, vol.56, n.4, suppl., pp.1289-1292. ISSN 1678-992X.  https://doi.org/10.1590/S0103-90161999000500035.

To verify the behaviour of three sugarcane varieties cultivated in vitro using media with different sources of nitrogen, an experiment was carried out under sterile conditions. Twelve treatments were used, represented by three sugarcane varieties: Co 997 (V1), SP 71-6949 (V2) and SP 70-1143 (V3), and four growth media, differing in the source of N: integral MS salts (M1-control); 4,3 g/L of glutamine as the only source of nitrogen (M2); KNO3 of MS salts as the only source of nitrogen (M3) and KNO3 of MS salts + 3,0 g/l of glutamine (M4). Five replicates were used in a completely randomized design. Based on the variables studied (shoot height and number), significant differences existed among the varieties, except for V1 and V2. There were also differences on growth media, except for M2 and M4. With respect to the shoot number/height ratio, the variety (V2) was superior when grown in media M1 and M3.
