Weakened carbon and nitrogen metabolisms under post-silking

发布时间：2022-02-20 20:46

　　Post-silking high temperature is one of the abiotic factors that affects waxy maize（Zea mays L. sinensis Kulesh） growth in southern China. We conducted a pot trial in 2016–2017 to study the effects of post-silking daytime heat stress（35°C） on the activities of enzymes involved in leaf carbon and nitrogen metabolisms and leaf reactive oxygen species（ROS） and water contents. This study could improve our understanding on dry matter accumulation and translocation and grain yield production. Results ...
