NAVARRO, Marlen; FEBLES, G; TORRES, Verena    NODA, Aida. Effect of moist and dry scarification on the emergence of Albizia lebbeck (L.) Benth. seedlings. []. , 33, 3, pp. 0-0. ISSN 0864-0394.

The application of different scarification methods to favour seedling emergence from A. lebbeck seeds stored under ambient conditions was evaluated, for which a completely randomized design was used with 4 x 13 and 3 x 13 factorial arrangement for moist and dry scarification, respectively. Significant interaction was found among the factors for moist scarification (P<0,001). The best values for the acid, hot water and soaking were found at 4 mos; they were lower than the control and among them only water and soaking and water and control were statistically different. The contrast between the values at 6 mos for the acid (6,3%) and the control (40,1%) stands out; in this last evaluation the highest emergence for moist scarification was achieved. In dry scarification, the highest percentage was obtained in the treatment based on the coat cut and 3 mos (71,0%), and differed statistically from the rest. In the cutting method all the emergence records were higher than the control. For the cut and puncture, statistical differences were detected only between 2 and 3 mos; in both the prevailing value was that of the cutting method. The emergence results allow to evaluate the coat cut as an appropriate method for A. lebbeck seeds, without obviating that soaking also constitutes an alternative for scarification.
