Germination tests were made on 7 Genisteae species of the genera Chamaespartium (I), Echinospartum (1), and Genista (5), using seed collected in 1991 or 1992 in Portugal. Three different temperature regimes were applied: (1) daily altemation of 10°C and 20°C, linked with a 12 hour photoperiod; (2) same conditions, except that the temperature altemated between 20°C and 30°C; (3) at first regime (I) during 2 days, subsequently followed by regime (2). For Echinospartum, regime (2) proved to be most favourable; Chamaespartium germinated best under regime (I); and the Genista species either preferred regime (3) or did equally well under regime (I) and (3)
