摘要
本文用酯酶同工酶电泳技术对北京市生产上的11个玉米杂交品种进行酯酶同工酶酶谱纯度测定,同时将被测定的杂交品种进行田间品种纯度检验。其酶谱纯度和品种纯度二者的回归方程Y=1.1288+0.9162x,相关系数γ=0.9094,对γ进行t测验结果为t=6.559>3.250。表明室内测定和室外检验结果之间存在着极显著的正相关关系。通过室内酶谱纯度测定结果,即可相应的对查出田间的品种纯度。
Zymogram purity of esterase isozyme in 11 Maize varieties on production of Beijing were determined by using electyophoresis of es-terase isozyme.It was compaered with the varietal purity of the Maize hybrids to be examined in the field.Regression equation of between Zymogram and varietal purity y=1.1288+0.9162X,regression coefficient r=0.9094,t value=6.559>3.25It Shows that the best significant positive correration relationship is presented between laboratory determination and field examinationResults of laboratory determination for Zymogram purity can check with the varietal purity in the field correlatively
