The Allopathic Effects of Cyperus Rotundus Extract on the Germination of Lycopersicon esculentum L. var Chef Flat
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 12
Abstract
This experiment was conducted to determine allopathic effects of Cyperus rotundus extracts on the tomato germination. It was a completely randomized design (CRD) with four replications, carried out in the laboratory of the Agricultural College of University Jiroft during 2011. The various test treatments were extracts of Cyperus rotundus taken from aerial organs, root, and combinations of both plant parts, at densities of 0, 25, 50, 75 and 100 percent. Experimental units were Petri dishes in depths and diameters of 3 and 9 cm, respectively. The shoot and root length, shoot and root fresh weight, germination percentage and rate was measured. The use of the cyperus extract reduced the germination, and it significantly decreased by increasing its in density, such that at the 75% and 100% densities, germination was terminated. Based on the test results, it could be said that the cyperus extract has a severe inhibitory effect on the tomato germination. With time passing, the germination speed decreased over the measurement period, and reached its minimum at day 14. The maximum fresh weight of the root and shoot were achieved from the control treatment (no extract).
