目的:观察皂荚植株开花特性,探讨猪牙皂的发育与形成规律。方法:定点观测皂荚嫁接株、实生株花的性别、形态变化、花序特征参数及开放动态。结果:实生株花序有雄花序、两性花序及杂性花序,嫁接株只有两性花序;只有雄花序的雄株只传粉不... 目的:观察皂荚植株开花特性,探讨猪牙皂的发育与形成规律。方法:定点观测皂荚嫁接株、实生株花的性别、形态变化、花序特征参数及开放动态。结果:实生株花序有雄花序、两性花序及杂性花序,嫁接株只有两性花序;只有雄花序的雄株只传粉不结果,具有两性花序、杂性花序的两性株、杂性株均可结果,实生株多结大皂角,嫁接株多结猪牙皂;嫁接株两性花序最大,实生株雄花序最小,实生株两性花序大小介于嫁接株两性花序与实生株雄花序之间;实生株雄花序着花数量最多,嫁接株与实生株两性花序着花数量相近;嫁接株开花早、花期长,实生株开花较晚、花期较短。结论:不同性质皂荚植株开花特性有明显差异,花蕾期柱头外露花、以猪牙皂植株枝条嫁接的植株多结猪牙皂,猪牙皂的形成与花期错位、植株遗传变异等有关。 展开更多

Wheat, triticale, tritordeum, barley, oat and rye are the most important crops in human consumptions and industry in the world. Transformation technology supplies a new source of improving Triticeae crops. In the past decade, transformation of wheat crops has considerably progressed. Many transgenic plants of Triticeae crops with various genes were produced via nricroprojectile bombardment, Agrobacterium-mediated transformation, PEG-uptake DNA technique, electroporation, microinjection, injection inflorescence and silicone carbide. Integration and expression of transgenes, inheritance and variation of transgenic plants have been studied. Technical improvements of genetic transformation for wheat crops will be extensively useful in commerce and benefit significantly to human being in the world. 展开更多
