dc.description.abstract At the end of monitoring the germination rate of five (05) exotic species (Stevia rebaudiana, Moringa oleifera, Carica papaya, Sesbania aculeate, Paulownia tomentosa) seeds introduced in Algeria (control seeds and seeds dipped in distilled water for 24h, 48h and 72h at two temperatures of 30 ° c and 40 ° c); The best germination rate is 85% in 24 hours at 30 ° C, 48 hours at 40 ° C and the witness of Sesbania aculeata. For Moringa oleifera germination rate is 70% at 24 hours 30 ° c. papaya Carica papaya germination rate 65% in 24 hours of treatment 40 ° C, Paulownia tomentosa 50% in 24 hours at 40 ° C and lastly Stevia rebaudiana 15% for the witness. Not marked germination for; Moringa oleifera 24 and 48 hours at 30 ° C also Stevia rebaudiana at 72 and 48 hours at 40 ° C, Paulownia tomentosa at 72 hours 40 ° c. The fastest germination rate is recorded in the seeds of; Paulownia tomentosa with 0.28 g / day for grains soaked in 24 hours at 40 ° C. Sesbania aculeata the fastest rate 0.47 g / d for controls and soaked grains in 24 hours at 30 ° C and 48 hours at 40 ° C, Stevia rebaudiana 0.08 g / d for controls, Carica papaya with 0.72 g / day for grains soaked in 24 hours at 30 ° C, Moringa oleifera with 0.39 g / d for grains soaked in 24 hours at 30 ° C.
