在种植前,用γ射线对薯蓣根茎进行剂量为100、500、2000拉德的辐射,可加速其生长发育并提高植株根茎中薯蓣皂苷配基(diosgenina)的含量。用γ射线辐射薄荷根茎使幼苗增多和促进根的生长。但是,目前对于多数药用植物,尚未能应用这种方法来改善种子发芽和加速植株的生长。种植薯蓣的目的是为了获得薯蓣皂苷配基,这种物质在医学上广泛用于治疗动脉硬化症。但是薯蓣在一般情况下生长缓慢,头两年更是如此。经过处理的植株生长到第3—4年时,根茎中薯蓣皂苷配基含量可达到8—4%。因此,在种植前应用电离辐射处理薯蓣根茎,以达到提高植株根茎中薯蓣
Before planting, irradiation of 100, 500, and 2000 rad radiation doses of y-rays on yam roots can accelerate its growth and increase the content of diosgenin in roots. Irradiation of peppermint rhizomes with gamma rays increases seedling growth and promotes root growth. However, for most medicinal plants, this method has not yet been applied to improve seed germination and accelerate plant growth. The purpose of planting yam is to obtain diosgenin, which is widely used in medical treatment for atherosclerosis. However, yam pods grow slowly in the general situation, especially in the first two years. After the treated plants are grown to the third to fourth years, the content of diosgenin in roots can reach 8-4%. Therefore, ionizing radiation is used to treat the roots of the yam before planting so as to increase the yam in the roots of the plant.
