Abstract:- The objective of this study was to screen inhibitory effects of selected herbs on plant growth. The peels of three species of Citrus, Citrus maxima (Burm.f) Merr., Citrus reticulata Blanco and Citrus aurantifolia (Christm.), were selected for various extractions. Three extraction solvents: methanol, 80% methanol and water were used in this study. The test methods were seed germination bioassay which focused on percent inhibition of seed germination, and seedling length bioassay that reflected the inhibitory effects on root elongation of seedling plants of lettuce seeds, Lactuca sativa L with suitable germination and growth rate as the representative for weeds in the test such as sensitivity, simplicity, low cost and suitability. The result showed that the 1 mg/ml of 80% methanol extracts of Citrus aurantifolia had significant inhibitory effects on germination of lettuce seeds. For the seedling length bioassay, three extracts of Citrus aurantifolia had inhibitory effects on root elongation of lettuce seeds with EC10 of 0.01 µg/ml, 0.11 µg/ml, 0.01 µg/ml for MeOH, 80% MeOH and aqueous extracts, respectively. The study is worthy of further investigation since this could provide potential bioherbicide and may lead to the discovery of new effective and applicable bioherbicide.
Keywords:- Citrus spp, seed germination bioassay, seedling length bioassay, bioherbicide. |
