野生中药材资源钩藤种子发芽研究

[目的]为探明钩藤种子的萌发条件及规律。[方法]以清水处理作对照,采用4种化学药剂(NaHCO3、KHCO3、K2CO3、NaClO)不同浓度的溶液浸种,并在光照培养箱内进行发芽试验。[结果]清水处理的钩藤种子发芽数和绝对发芽率(80%以上)均明显高于其他处理。[结论]钩藤种子成熟胚不存在休眠现象,种皮也不存在抑制作用,常规保湿处理即可诱导种子萌发。

[Object] The research aimed to find out seed germination conditions and regulations. [Method] Seeds were soaked by clear water and 4 chemical agents of different concentrations (NaHCO3, KHCO3, K2CO3, NaClO) then conducted germination test in illumination box. [Result] Seed germination number and absolute germination rate (above 80%) in water treatment group was obviously higher than other treatments. [Conclusion] No dormancy phenomenon in mature embryo and no inhibition in seed coat, so conventional moist treatment can induct seed germination.
