核桃凋落叶浸提液和腐解液对萝卜种子萌发及其生理特性的影响

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

摘要: 本试验采用培养皿试纸法，以核桃（Juglans regia）为供体对象，对萝卜种子进行萌发试验，通过浸提和腐解两种方式处理核桃凋落叶，分析其不同浓度（25 mg·mL^-1、50 mg·mL^-1和100 mg·mL^-1）的浸提液和腐解液对萝卜（Raphanus sativus）种子萌发及萌发过程中生理特性的影响。结果表明：核桃凋落叶浸提液和腐解液对萝卜种子萌发具有较明显的抑制作用，且随着处理液浓度的升高而增强，同时在一定的时间范围内，也随凋落叶腐解时间的延长而呈增强趋势。

Abstract: 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.
