为了探明SOD、POD、PPO活性与棉花对红腐病抗性的关系,为棉花抗病育种提供理论依据,笔者在温室条件下,对不同棉花品种感染棉花红腐病菌后体内多酚氧化酶(PPO)、过氧化物酶(POD)、超氧化物歧化酶(SOD)3种酶活性的变化进行了测定,结果表明,棉株受红腐病菌侵染后,体内PPO、POD、SOD 3种酶活性均显著增加,抗病品种中棉29的3种酶活性均高于感病品种泗棉3号,而且前者酶活提高的速度快于后者,提示PPO、POD、SOD的活性均与棉花品种对红腐病的抗病性密切相关,3种酶在棉花植株抗病中可能均具有较大的作用。

借鉴国外文献关于就业与居住空间均衡对交通出行影响的研究方法,构造了测度就业-居住空间均衡的指数,对上海进行了实证分析。结果显示,上海的就业-居住空间均衡性趋于减弱,表现为,核心区和紧邻外围区以服务业就业为主导功能,多数外围区和近郊区以居住功能占主导,远郊区又是以就业为主要性质,但以制造业为主。城市交通层面上的后果是,跨区交通出行增加,平均出行时距和距离上升。针对上述结论对现行城市规划政策进行检讨,并得出应该增加用地功能复合性等政策启示。
