OPTIMIZATION OF MICROCLONAL PROPAGATION METHODS OF JUGLANS REGIA L.

This scientific article shows that, in the propagation of Juglans regia L., the composition of the culture medium is the main source of variability in the proliferation process. Regardless of the genotype used, the growth of microshoots was better in DKW medium than in MS medium. The results indicate that growth occurred mainly due to the elongation of internodes rather than an increase in the number of nodes. In addition, the size of calli formed on DKW medium was larger than those on MS medium. Values in each column are presented as mean ± standard error (SE). n = 20; mean values of explant shoots marked with different letters differ significantly at P < 0.05.
