Rice plants play a pivotal role in methane emission and more than 90% of CH4 released from a rice field during a growing season can be emitted by rice plant-mediated transport. Studying the relationship between rice plant aerenchyma system and methane emission may provide the theoretical and practical basis for reducing methane emission in the course of rice culturing and breeding practice. In a field experiment during early and late rice seasons in 2005, methane emission amount and 16 quantitative characters of plant internodal tissues above g...
