Effect of pre-germination treatments on the emergence and initial growth of Talisia oliviformis (Kunth) Radlk. Pastos y Forrajes [online]. 2017, vol.40, n.1, pp.16-22. ISSN 0864-0394.

The objective of the trial was to evaluate the effect of pre-germination treatments on the emergence and initial growth of Talisia oliviformis (Kunth) Radlk, through six pre-germination treatments: seeds without seed coat (SC) without soaking (T1), T1 plus soaking during 24 h (T2) and 48 h in drinking water (T3), seeds with SC without soaking (T4), T4 plus soaking during 24 h (T5) and 48 h (T6). A completely randomized design was used, with six repetitions and fifty seeds as experimental unit. The measurements performed were: emergence percentage (EP), plant height (PH) and number of leaves (NL). Interaction of the factors seed coat (SC) and soaking time (ST) was found for the EP. The pre-germination treatments were different among themselves; T5 reached the highest percentage (85 %), although T4 achieved 72 % of EP, value which is also considered adequate. The interaction between SC and ST significantly influenced the PH; T1, T2, T4, T5 and T6 did not differ among themselves, although T6 had equal performance as T1 and T3. Regarding the NL, no differences were found among the treatments for any of the studied factors. It is concluded that the interaction of the seed coat and the soaking time influenced the EP and PH. The treatments with seeds with SC soaked during 24 h and without soaking reached the highest emergence percentages (85 and 72 %, respectively). Both techniques are environmentalist, simple, practical and economical.
