Effect of alfalfa foliage and alfalfa soil extracts on alfalfa seedling vigor

, : Effect of alfalfa foliage and alfalfa soil extracts on alfalfa seedling vigor. Report of the twenty ninth alfalfa improvement conference: 38

The effects of Medicago sativa foliage on seedling vigour were investigated in vitro by germinating seeds in extracts of 0, 1.25, 1.66, 2.5 and 5 g ground foliage/100 ml water. Both percentage and rate of germination were proportionally reduced by addition of foliage extract to the medium with a greater response at 2 or 4 days than at 7 days and at 25 than at 20 degrees C. Radicle and hypocotyl lengths were reduced after 7 days by 1.66 g/100 ml.
