Seed Polymorphism of Terminalia laxiflora Engl. and Diels seeds in relation to Germination

Abstract

T. laxiflora is one of the important Sudanese trees, which has low seed germination problem. In some cases the germination was found to be related to seed polymorphism, so this study was carried out to investigate the seed polymorphism and vaibilty of this species with regard to germination. Germination percentage, sesds length, seed width, wing length and number of wings were examined in T. laxiflora 10 trees in ElNour forest east of Eldamazin city in Blue Nile State in season 2007. The results showed that seed length, seed width, wing length were significantly different in the 10 trees but No of wings was 2 for all trees. Germination percentage has a significant variation but it was not found to be associated with seed polymorphism.
