In this experiment, seeds have been used as explants, MS as the basic medium adding NAA and 6-BA on different concentrations to research rapid propagation technology of Sophora flavescens var. The results shows that the best method of sterilization for seeds is 70% ethanol(8 s)+0.1% HgCl2(8 min) which have the lowest contamination rate and the highest seedling rate. The optimal culture medium for subculture is MS+0.1 mg/L NAA+3.0 mg/L 6-BA and MS+0.5 mg/L NAA+3.0 mg/L 6-BA, the highest multiplication rate is 120.2%, 1/2 MS+0.1 mg/L NAA is the best medium for rooting culture. The tissue culture seedling have 1~2 cm roots could be domesticated with natural light for 5 days, and then transplanted in vermiculite have higher survival rate.

植物标本在教学和科学研究中占有重要的地位,其采集、制作及保存是实训教学中必不可少的基础知识和技能。作者根据新世纪农业高职高专应用型人才培养的需要,从学院的实际情况出发,结合传统植物标本的制作方法,通过多年实践创新,探索出覆膜原色植物腊叶标本制作技术,分析了覆膜原色植物标本与常规的植物腊叶标本优缺点;指出覆膜原色植物腊叶标本具有真实,美观,防虫,防变质,携带方便,能长期保存的优点,而且对增强学生亲身实践,动手操作的能力,提高学习兴趣,方便教学等方面有重要作用。

<正>苦参(Sophora flavescensAi)t为豆科槐属植物,是我国传统药用植物。苦参的根为常用中药材,有明显的抗菌、消炎、杀虫作用。除在医药上被广泛应用外,近年来又被广泛用于生物农药的开发,随着对苦参中提取的苦参碱应用研究的突破,苦参用量逐渐加大。但是苦参种子一般于10月中下旬成熟,

The experiment was conducted to study the effects of temperatures and illumination on germination of Sophora flavescens seeds.The result showed that each of the imbibition rate,germination rate and germination index were different significantly(p0.01) at different temperatures.The imbibition rate and germination rate were very low when the temperature for germination was 10 ℃,then were faster when the temperature was 20 ℃,25 ℃,30 ℃ respectively.The mustiness rate was the highest when the temperature was 35 ℃,and the germination rate was decreased also.The optimal temperature for germination was 20 ℃ to 30 ℃.Dark more favored germination than light though the seeds could germinate at light condition.

根据新世纪农业高职应用型人才培养的需要,结合甘肃农业职业技术学院的实际情况,从实验室建设、改进教学方式、强化技能训练、培养严谨工作态度等方面探索了农业高职植物学实验课教学改革的一些问题。
