WENCOMO, Hilda B    ORTIZ, R. Recovery capacity of 23 Leucaena spp. accessions after pruning. []. , 34, 1, pp. 53-68. ISSN 0864-0394.

Twenty three Leucaena spp. accessions were evaluated for two years, in order to know the variability existing in the population regarding the recovery capacity after pruning. When the plants were higher than 2 m, the uniformity pruning was made at 1 m above the soil level. The measurements were: stem diameter, number of regrowths and their length with a weekly frequency, from which the growth rate of each accession was calculated; in addition, yield was determined. The main component, cluster and simple lineal regression analyses were made through the statistical program SPSS version 11.5 for Microsoft Windows®. Variability was observed in the evaluated indicators (86,11% accumulated in the component) and they all contributed to its explanation. In turn, the cluster analysis allowed the formation of three groups. All the accessions were concluded to show recovery capacity after pruning, with differences among them. The accessions Leucaena leucocephala cv. Cunningham, cv. Peru, CIAT-9119, CIAT-9438, CIAT-751, CIAT-7988, CIAT-7384, CIAT-7929, CIAT-17480, cv. Ipil-Ipil and cv. CNIA-250; L. lanceolata CIAT-17255 and CIAT-17501 and L. diversifolia CIAT-17270 were the ones with higher recovery capacity. For such reason it is recommended, in future studies related to the characterization, evaluation and selection of these species, to make studies including their persistence in time under pruning conditions, as well as their use in the development of new silvopastoral systems.
