REINO, J; GONZALEZ, Yolanda; TORAL, Odalys  and  IGLESIAS, J. M. Quality of accessions collected in the central-eastern region of Cuba (Technical note). Pastos y Forrajes [online]. 2010, vol.33, n.2, pp. 1-1. ISSN 0864-0394.

A prospection was made in 2005, in the central-eastern region of Cuba and seeds from 43 accessions (36 tree legumes and seven herbaceous ones) were collected. Afterwards, a germination test was conducted in order to learn the quality of the seeds (with seed coat cut), in Petri dishes on river sand. The number of seeds used in each accession was different (according to the collected ones) and only one replication was used (without statistical design). The best-quality seeds corresponded to the accessions Bauhinia acuminata, Bauhinia purpurea (from Nuevitas and Vertientes), Cassia fistula, Albizia kalkora, Centrosema sp. and Centrosema brasilianum (100% germination), as well as Calopogonium caeruleum (90%) and Albizia lucida (91,6%). Seven accessions did not germinate. Most of them achieved high germination (in bags), although in such species as Bauhinia hookeli, B. acuminata, A. lebbeck, C. caeruleum, C. brasilianum, Desmodium sp., and Teramnus sp. it was low and two accessions did not survive. The germplasm of the EEPF «Indio Hatuey» increased in 34 accessions. The importance of knowing the seed quality and the relation between this indicator and their deterioration was proven, due to the large variability shown by the germination percentage in seeds collected in the same time period.
