Effect of different treatments on dormancy breaking of wild oat (Avenafatua)

2015 International Journal of Biosciences  
This study was conducted at the National Tree Seed Centre of the Forestry Research Centre at Soba-Khartoum, Sudan, 2009, to investigate the importance of the morphological abnormalities in seedling as polyembryony of Ziziphus spina-christi (L.) Wild, as an important indigenous and multipurpose species in Sudan. The study revealed the strategy of the species of producing large kernels that contain 2-seeded to guarantee the production of twin seedlings for survival purposes. This phenomenon was

The results showed a very high significant response of twin seedlings' emergence to the dormancy breaking treatments, and twin seedlings' emergence showed a very high significant response to provenance.
