Abstract

ROSSETTO, Claudia Antonia Vieira  and  ALVES, Elisabete Pacheco. Arachis pintoi seeds as affect by pre-germination. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp. 174-179. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542008000100025.

The aim was to evaluate the effects of previous treatments in the Arachis pintoi Krapov. & W. C. Greg. seeds germination and vigour. A completely randomized design with four replication arranged in a factorial scheme (2 lots x 7 treatments), was used. For this, two commercial lots of seeds with intact pods of Arachis pintoi, cv. Amarillo, stored by six and 12 months, were used. In each lot, the treatments were employed through pod removal or not, the pod breakage and the exposition of intact pods at 45ºC for 48 and 72 hours and to the hidratation for 24 and 48 hours. Further, for treatment, it was performed the evaluation of water content, germination and vigor (first count of germination and seedling emergency). The pod removal became the seeds vulnerable to the action of microorganism. Heating at 45ºC for 48 and 72 hours caused reduction of the nom-germinated seeds. The hidratation for 48 hours favored the Arachis pintoi seed germination and vigour.
