Effets de dix traitements sur la germination des akènes d'Ambrosia maritima L

Abstract

Effects of ten treatments on the germination of Ambrosia maritima L. seeds. Stratification of Ambrosia maritima seeds at + 10°C for 7 days appeared to be the best practical method to break their embryonic dormancy with 80 % germination occuring 18 days following the treatment, compared to 17 % for the control. This experiment confirms the susceptibility of embryonic dormancy to low temperatures. Treatments with waterat + 80°C or concentrated H2S04 for 15 mn and mechanical treatments eliminating the inhibition effect of seed integuments also gave higher results (43 to 53 % germination rate). However, germination in the control group was significantly higher than in the group of seeds subjected to dry heat. Although the first results obtained on the field from these trials were satisfactory, further research is needed to confirm them.
