FLORES, Emmy; MORATINOS, P; RAMIREZ, Maribel  and  GARCIA, D. E. Evaluation of the emergence and the initial morphological characteristics of Tamarindus indica L. with agroforestry purposes. Pastos y Forrajes [online]. 2009, vol.32, n.2, pp. 1-1. ISSN 0864-0394.

In the Zulia state, Venezuela, a first trial was conducted to evaluate the effect of planting position (PP) and storage time (ST) of Tamarindus indica L. seeds, and in a second trial the emergence and morphological characteristics of the seedlings were analyzed by means of a completely randomized design. The PP corresponded to seeds planted with the hilum facing down, the hilum facing up horizontally placed; while ST was one and eight months. After 30 days the effects of PP, ST and the PP x ST interaction were significant on the emergence percentage (EP), emergence rate (ER), seedling height (SH), root length (RL), number of leaves (NL) and number of nodes (NN) per seedling. The seeds with one month of storage and planted with the hilum facing down showed the best results (EP: 97,5%; ER: 22,3 days); while the newly-harvested seeds without storage and planted with the hilum facing down contributed outstanding results (EP: 96,56%; ER: 22,92 days). A significant correlation was observed in all the variables measured, excluding NL with CH and SD with CH and NL. It is concluded that in order to efficaciously propagate T. indica and establish agroforestry systems, newly-harvested seeds or seeds with one month of storage should be used, planting them with the hilum facing down.
