Effect of the Leached Liquid and the Decomposed Liquid of the Leaf Litter of Juglans regia L. on the Germination and the Physiological Characteristics of the Raphanus sativus Seeds

In this paper,studies were made of the effects of the two liquids which both have three various concentrations (25 mg·mL^-1, 50 mg·mL^-1, 100 mg·mL^-1) on the germination and the physiological characteristics of Raphanus sativus seeds. In conclusion, there existed an obvious inhibiting effect of the leached and the decomposed liquid of the leaf litter of Juglans regia on the germination of the Raphanus sativus seeds, and as the increasing of the concentration of the two liquids, the effects would be more stronger. Simultaneously, within a certain amount of time, the inhibiting effects would increase along with the time extension of the litter leaf decomposing.
