【摘要】 试验结果表明,鸡骨草种子具有硬实特性,硬实率随种子成熟度的增加而增大。种子的干燥快慢对硬实的形成影响很大,晒干种,干燥快,硬实率高,发芽率较低;阴干种,干燥慢,硬实率低,发芽率较高。用砂擦、砂纸摩擦、热水浸泡或浓硫酸处理硬实种子,可使种子发芽势从30%左右提高到60%以上,发芽率从40%左右提高到80%以上。更多还原

【Abstract】 Experimental evidence proved that the seed of jigucao (Abrus cantoniensis) is characterized by its extreme hardness which is related to its degree of maturity and highly influential to its rate of germination. When it is rapidly dried under sunshine, its hardness greatly exceeds that which is dried in the dark shade. When abrasives, such as sand or sand paper were used to polish its surface, or by soaking in hot water or concentrated sulfuric acid, its rate of germination can be raised from about 40% to 80%.更多还原
