Despite the major ecological and economical relevance of forest species, little is known about their seedling establishmentand seed germination, as well as the damage effects to seeds at these stages. This work aimed to assess the effects of partial cotyledonloss on the seed germination and early seedling establishment of Anadenanthera colubrina. Therefore, whole (control) and split seeds(with 1/8, 1/4, and ½ of their size cut) were evaluated. The seeds were then germinated and the early growth of seedlings was assessed.The treatments had no effect on seed germination, however, they influenced seedling survival and establishment. The highestmortality and growth reduction values were obtained with the most severe cotyledon removal. This indicates that the tegument andthe partial cotyledon loss do not represent a barrier against seed germination. However, considerable damages may be detrimental toestablishment and survival of A. colubrina seedlings. |
