BRENAN Cotyledon integrity on Anadenanthera colubrina. (FABACEAE - MIMOSOIDEAE) GERMINATION AND EARLY ESTABLISHMENT 227 Hisaias de Souza Almeida1, Anne Priscila Dias Gonzaga2, Helaine de Sousa3, Yule Roberta Ferreira Nunes4, Henrique Nery Cipriani5 (received: September 16, 2009; accepted: March 31, 2010) ABSTRACT: Despite the major ecological and economical relevance of forest species, little is known about their seedling establishment and seed germination, as well as the damage effects to seeds at these stages.
This work aimed to assess the effects of partial cotyledon loss 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 highest mortality and growth reduction values were obtained with the most severe cotyledon removal.
This indicates that the tegument and the partial cotyledon loss do not represent a barrier a...
