BARRAZA A., Fernando. GERMINATION OF MORINGA SEEDS (Moringa oleifera Lam.) IN DIFFERENT WATER IMBIBITION TIMES. rev.udcaactual.divulg.cient. [online]. 2017, vol.20, n.1, pp.71-77. ISSN 0123-4226.

Sowing of the moringa crop with gamic seeds has advantages over vegetative propagation with stakes due to the good availability of seeds, rapidity in the nursery phase, ease of transplantation, economy in the work and best definitive anchorage. However, it has been reported that mature seeds have a low percentage of germination, therefore a research was made at the Universidad de Córdoba, Colombia, with the objective of establishing the effect of the imbibition of seeds in water on germination percentage. A bioassay with seeds extracted from a one year old tree, planted in the experimental field of vegetable crops was carried out. The experimental design used was completely randomized and three treatments were applied, seed imbibition in water during 24h, seed imbibition in water during 48h and seed imbibition in water during 72h having as control seeds without imbibition in water. The germination percentage GP data were adjusted to the logistic model and the absolute rate of germination ARG and relative rate of germination RRG were obtained. According to the results it was established that the GP decreased at a longer seed imbibition time and AGR decreased from 29 seedsâ^™day^-1 to 7 seedsâ^™day^-1.

Keywords : Imbibition in water; logistic model; germination.
