NAVARRO, Marlen; FEBLES, G; TORRES, Verena  and  NODA, Aida. Effect of moist and dry scarification on the germination capacity of seeds from Albizia lebbeck (L.) Benth. Pastos y Forrajes [online]. 2010, vol.33, n.2, pp. 1-1. ISSN 0864-0394.

With the objective of favoring germination in A. lebbeck seeds stored under ambient conditions, different pre-planting methods were evaluated by means of a completely randomized design with 4 x 13 and 3 x 13 factorial arrangement for moist and dry scarification, respectively. In moist scarification significant interaction was found among the studied factors (P<0,001). No statistical differences were observed between the acid and the hot water, in the seeds evaluated at 1, 3, 6 and 7 mos; while the same evaluations were statistically different from the control and in all cases the values were lower than the latter. All the soaking and control evaluations were not significant among themselves, while they differed from the hot water and the acid. In the dry scarification the germination capacity showed significant interaction (P<0,001). The highest values were reported in 1, 2 and 3 mos in seeds with one cut; these percentages did not differ among themselves but they did differ from the others. When comparing the cut with the puncture, a statistically different behavior was observed; in all the evaluations the lowest values were those of the puncture. It is necessary to emphasize the efficacy of the seed coat cut and the soaking for 24 hours in water at ambient temperature as dry and moist scarification treatments, respectively, in spite of the acceptable results shown by the control.
