【摘要】 新麦草是优良牧草种质资源之一 本文对新麦草 (Pasthyrostaehysperinnes)的核型进行分析 ,用处理液对新麦草进行前、后低渗处理 ,席夫试剂染色制片 实验结果表明 ,新麦草染色体数目为 2n =14,核型公式 2n =2x =12m +2sm( 2SAT)更多还原

【Abstract】 The chromosome karyotype of P Perinnis was analyzed in this paper The root tip were treatsd with treatment solutions to low osmosis,then put dyeing with schiff The result shows,that chromosome number is 2n=14,the karyotype formula is as follows:2n=2x=14=12m+2sm (2SAT)更多还原
