Lily Cultivars Have Allelopathic Potential in Controlling Orobanche aegyptiaca Persoon
Fig 5
Induction of O. aegyptiaca Pers. germination by aqueous and methanol extracts of lily underground (A) and above-ground (B) organs at the flowering stage.
Two types of organs were tested, (A) underground organs and (B) above-ground organs. Two types of extracts were tested, (A1 and B1) aqueous and (A2 and B2) methanol. Four concentrations of extracts were assessed: undiluted and 10-fold, 100-fold and 1000-fold dilutions. Abbreviations: R-Sor, root extracts of Sorbonne; R-Ceb, root extracts of Ceb Dazzle; B-Sor, bulb extracts of Sorbonne; B-Ceb, bulb extracts of Ceb Dazzle; S-Sor, scale leaf extracts of Sorbonne; S-Ceb, scale leaf extracts of Ceb Dazzle; P-Sor, prop root extracts of Sorbonne; P-Ceb, prop root extracts of Ceb Dazzle; P-Lor, prop root extracts of L.formolongo.; A-Sor, aerial stem extracts of Sorbonne; A-Ceb, aerial stem extracts of Ceb Dazzle; A-Lor, aerial stem extracts of L.formolongo.; L-Sor, leaf extracts of Sorbonne; L-Ceb, leaf extracts of Ceb Dazzle; L-Lor, leaf extracts of L.formolongo; CK1, GR24 as positive control; CK2, Distilled water as negative control; CK3, Methanol as negative control. The dotted black lines represent 20% and 40% position, respectively. Error bars represent the standard error of the mean. Different small letters above the error bars indicate significant differences at 0.05 (ANOVA and Duncan's multiple range test). Matching letters in the same color column indicates that there were no significant differences between treatments.
