Influence of water availability and grapevine phenological stage on the spatial variation in soil respiration

摘要

Background and Aims: An understanding of spatial variation in soil respiration is critical to determining the carbon balance in grapevines. The effect of soil water content on soil respiration during different phenological stages in two grapevine cultivars, Grenache and Tempranillo, was studied over two seasons (2013 and 2014).
