Diurnal and seasonal variation in root xylem embolism in neotropical savanna woody species: impact on stomatal control of plant water status

ABSTRACT Vulnerability to water‐stress‐induced embolism and variation in the degree of native embolism were measured in lateral roots of four co‐occurring neotropical savanna tree species. Root embolism varied diurnally and seasonally. Late in the dry season, loss of root xylem conductivity reached...
