改良

An improved CTAB method was used to extract winter buds and tender leaf of ten Species of Spiraea DNA and factors which affect the RAPD amplification were optimized and selected.

试验以10种绣线菊属植物为材料，采用改良CTAB法进行冬芽和嫩叶的总DNA提取并对影响RAPD扩增效果的因素进行优化。

Having used 10 kinds of Spiraea resources for the material,respectively SDS method,high-salt low pH method and the improved CTAB method for DNA of young leaves of the extraction,detection and comparison;the use of tested template for RAPD primers screening.

以10种绣线菊属植物资源为材料，分别用SDS法、高盐低pH法及改良的CTAB法对幼嫩叶片进行DNA提取并进检测比较，利用经过检测的模板对RAPD引物进行筛选。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.

首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程，结果表明：(1)使用经过改良的MS培养基（不加氨基酸和维生素，pH值为6.2，琼脂和蔗糖浓度均为1%）能在55 d左右的时间利用孢子培养获得植物体；(2)用0.1%的次氯酸钠溶液，消毒5 s是消毒孢子的最佳方案；(3)油体在孢子萌发初期为均一型，到幼叶发生后，成为可见的聚合型，但聚合的程度比野生材料要弱。

In this paper, we overviewed the relationship between male gametophytic selection and phenotype of its sporophyte, genetic differentiation and its application in plant genetic improvement, so it would be provided reference information for correlated research of male gametophytic selection.

本文主要概述雄配子体选择与孢子体表型的关系、遗传分化效应及其在植物遗传改良中的应用，以期为雄配子选择相关研究提供参考

Main results shown as follows:Three methods—SDS method, simple CTAB method and improved CTAB method were used to extract genomic DNA from sporophyte of Laminaria.

主要结果如下：对分别用SDS法、常规CTAB法、改良CTAB法三种方法提取的海带基因组DNA，进行紫外吸收检测、电泳检测和RAPD扩增检测。
