| This work aimed to study the effects of different temperature conditions on the germination of L. bardanoides and C. sphaerocephala seeds, compare the germination rates of these two species and estimate the occurrence of embryoless seeds. The results indicated that the best temperatures for the germination of L. bardanoides seeds were 20, 25 and 20-30ºC and for C. sphaerocephala, 20-35ºC and 40.32 µmol m-²s-¹ irradiance; L. bardanoides had a higher germination rate since the number of seeds with embryos higher compared with C. sphaerocephala. |
