MARTIN, G et al. Evaluation of the vegetative reproduction capacity of mulberry (Morus alba L.) varieties. Pastos y Forrajes [online]. 2014, vol.37, n.2, pp. 151-157. ISSN 0864-0394.

In order to evaluate the effect of variety and branch part on the leaf and root sprouting of propagules, five mulberry varieties (tigreada, yu-12, yu-62, murcia and universidad) were studied. The branches were divided into three parts (basal, medial and apical), which originated a total of 15 treatments. The quantity and percentage of sprouted and rooted propagules, number of branches, number of leaves and root weight, were evaluated. Yu-12 and tigreada had the highest sprouting (100 and 98 %, respectively). However, tigreada stood out in rooting (70 % of the total planted cuttings) and the root weight (2,67 g), in which it significantly differed (p < 0,05) from the other varieties. In addition, when using the basal and medial parts the highest sprouting percentage was obtained (93 and 90 %, respectively). The interaction of variety and branch part was significant; the best results were obtained in the tigreada variety basal part , regarding the number of branches and leaves. Tigreada showed the best morphoagronomic performance during the experimental period; while yu-12, yu-62, universidad and murcia did not respond efficiently to reproduction from propagules. The basal and medial parts were determining in the leaf and root sprouting and in the root weight. To repeat these experiments in nursery, in different months of the year, and to use products that stimulate propagule rooting is recommended.
