Resistance of a seedling to the herbicide 1,1'-ethylene-2,2'-dipyridylium bromide (diquat) can be used as a selective technique for photosynthesis mutants in Zea mays L. Diquat requires reduction by the light reaction in order to kill leaf cells and, therefore, nonphotosynthetic mutants survive. This technique was tested using known mutants and is applicable to larger samples of plants than previous techniques. Resistance to diquat should allow selection of mutants on the oxidizing side of photosystem II which are not previously available in higher plants.
幼苗对除草剂 1,1'-乙烯-2,2'-联吡啶溴化物（敌草快）的抗性可用作玉米光合作用突变体的选择性技术。敌草快需要在光反应中被还原才能杀死叶细胞，因此非光合作用突变体得以存活。该技术已用于已知突变体的测试，并且比以前的技术更适用于更多的植物样本。对敌草快的抗性应允许选择在光合作用系统 II 的氧化侧的突变体，这些突变体在高等植物中以前是不可用的。
