一、目的意义:观察幼穗分化是为了进一步了解三麦的生长发育过程,结合苗期外表形态的特征,采取相应的管理措施,来提高三麦的产量。二、观察时所需的工具:双筒立体解剖镜解剖针、载玻片。三、采集和剥制标本:首先按不同品种或不同播种期的麦苗分别采集回来,用清水冲洗干净,再用纱布或抹布把水吸干,将分蘖剔去,只剩麦苗的主茎,随后用解剖针从麦苗的基部将叶鞘轻轻地剖开,由表及里地
First, the purpose of the meaning: Observation of spike differentiation in order to further understand the growth and development of the three wheat, combined with the characteristics of seedling appearance patterns, take appropriate management measures to improve the yield of three wheat. Second, the tools required for observation: binocular stereo anatomical dissection needle, slide. Third, the collection and stripping of specimens: First of all by different varieties or different sowing of wheat seedlings were collected back, rinse with water, and then the gauze or rag the water to dry, the tiller ticked out, leaving only the main stem of wheat seedlings, then Use a dissection needle to gently cut the sheath from the base of the barley seedlings from the surface to the ground
