Abstract
本发明提供了一种用于诱导酸浆植株再生的培养基,以水为溶剂,包括以下浓度的组分:NH4NO3 200~1800mg/L、MgSO4 150~400mg/L、Na2EDTA 20~40mg/L、FeSO4 10~35mg/L、H3BO3 1~10mg/L、ZnSO4 2~10mg/L、NaMoO4 0.1~0.3mg/L、CuSO4 0.01~0.03mg/L、CoCl2 0.01~0.03mg/L、肌醇2~120mg/L、烟酸0.05~0.8mg/L、盐酸吡哆醇0.05~0.8mg/L、硫胺素005~1.2mg/L、甘氨酸0.5~2.5mg/L、6‑苄基氨基嘌呤0.05~1.5mg/L、萘乙酸0.01~0.05mg/L、蔗糖20~40mg/L和琼脂3~10mg/L。采用本发明提供的培养基,培养基污染率为0~3%,酸浆当年嫩茎诱导分化成苗率为75~95%。
Description
技术领域
本发明属于植物组织培养技术领域,尤其涉及一种诱导酸浆植株再生的培养基及培养方法。
背景技术
酸浆(拉丁文名:Physali alkekengi L.)又名红菇娘、挂金灯等,原产于中国,南北均有野生资源分布。酸浆为茄科酸浆属多年生直立草本植物,株高50~80cm,地上茎常不分枝,有纵棱,茎节膨大,幼茎被有较密的柔毛。根状茎白色,横卧地下,多分枝,节部有不定根。酸浆具有清热、解毒、利尿、降压、强心、抑菌等功能。主治热咳、咽痛、音哑、急性扁挑体炎、小便不利和水肿等病。酸浆果实中含有人体需要的多种营养成分,其中钙的含量是西红柿的73.1倍、胡萝卜的13.8倍,维生素C的含量是西红柿的6.4倍、胡萝卜的5.4倍。由于其独特的风味和丰富的营养,利用酸浆加工而成的饮料、果酒、食品和药物具有良好的市场前景。
现今对酸浆药食的需求量逐年递增,为了满足市场的需要、提高酸浆产量,扩大酸浆种植势在必行。虽然采用外植体组织培养能够降低污染率,而且使得反季节育苗更为有效,但是目前的酸浆外植体组织培养技术存在诱导分化成苗率低的问题。
发明内容
有鉴于此,本发明的目的在于针对现有技术的不足,而提供一种用于诱导酸浆植株再生的培养基,使该培养基能够提高成苗率。
为了实现上述发明目的,本发明提供以下技术方案:
一种用于诱导酸浆植株再生的培养基,以水为溶剂,包括以下浓度的组分:
NH4NO3 200~1800mg/L、MgSO4 150~400mg/L、Na2EDTA 20~40mg/L、FeSO4 10~35mg/L、H3BO3 1~10mg/L、ZnSO4 2~10mg/L、NaMoO4 0.1~0.3mg/L、CuSO4 0.01~0.03mg/L、CoCl2 0.01~0.03mg/L、肌醇2~120mg/L、烟酸0.05~0.8mg/L、盐酸吡哆醇0.05~0.8mg/L、硫胺素0.05~1.2mg/L、甘氨酸0.5~2.5mg/L、6-苄基氨基嘌呤0.05~1.5mg/L、萘乙酸0.01~0.05mg/L、蔗糖20~40g/L和琼脂3~10g/L。
