Studies on the biology of eucalyptus micro theca f. Muell in the gezira, sudan i. The behaviour of the seed

Abstract

Eucalyptus microtheca has proved to be a success on the heavy clay soils of the Gezira. This tree species not only seeds regularly and prolifically during the summer, but also, though rarely, seeds during the winter. The germination behaviour of the seeds of this species is satisfactory, and the poorest stock gives an adequate number of seedlings for planting out. The germination behaviour was found to be largely affected by the locality and negatively correlated with the storage period. Seed index was not found to affect the final percentage gernination
