Allelopathic Effects of Eucalyptus (Eucalyptus ssp) on Germination of Genotype Roselle (Hibiscus sabdariffa L.)

Abstract

This study is conducted in the laboratory of State board for seed testing and certification (S.B.S.T.C) – Branch of Al – Diwaniyah ,to determine the effect allelopathic of aqueous extracts of leaves eucalyptus tree (Eucalyptus ssp) (0 , 1% , 2% and 4% g/100 ml) in seed germination & growth of seedling three genotype from crop medical Roselle (Hibiscus sabdariffa L.) (White , Planned and Red). The results showed to the existence of significant differences for all traits, including the rate & speed of germination , length & dry weight of the assembled root and shoot between the stress allelopathic compared to the control treatment in addition to the differences of the genotypes and interaction with allelopathic treatments.
