Temperatura y germinación de las semillas de Dalbergia retusa (Papilionaceae), árbol en peligro de extinción

The effec! of ternperature over Dalbergia retusa Hernsl. germination was studied in the laboratory. Seeds were disinfected and placed in Petri dishes for germination at 15, 20, 25, 30, 35, 40, and 45 oc. Germination percentage and the hypocotyl-radicle length were rneasured after three and five days...
