Productivity of minicepas and rooting of minicuttings of Luehea divaricata Mart. & Zucc. in the different seasons of the year

The objective of this work was analyze the productivity of the minicepas and the rooting of minicuttings from seminal origin of Luehea divaricata in seasons. The first test evaluated the productivity of the minijardim, in which the treatments consisted of eight minicuttings collections. In the second test were evaluated the collections in seasons, the period of cultivation in each season and its interaction. The productivity was higher in two collections in the summer and one in the spring, which resulted in more than five minicuttings by minicepa in each collection; the first collection in the summer and the first two in the spring presented lower averages, but all higher than the highest winter and autumn averages. For root formation, at 30 days, the mean was 95% and at 60 days at 100%. The highest number of roots was observed in the summer, with 11.47 roots by minicut. In relation to the length of roots, numer of secondary roots and leaves, there was more development in summer and spring, mainly at 60 days. The productivity of the minicepas is higher in the summer and this season also produces more developed seedlings of Luehea divaricata by minicutting technique. However, the minicutting technique, under the conditions evaluated, may continue throughout the year, with collections also in autumn, winter and spring. Minicutting technique is an efficient alternative for the propagation of the species, obtaining, at 60 days of cultivation, seedlings with greater development.
