Intervention effect Many girdled trees later showed absent or apparently downward xylem sap flow.
Intervention effect Air emboli in laboratory vessels changed heat-rise rate significantly without significantly changing sap-flow speed.

Other claims from this paper (9)

Intervention effect The decrease in grain weight with irregular disposition was more remarkable in Fujiminori than in Manryo.
Mechanism Decrease of grain weight was caused by a decrease in the number of panicles per unit area.

Intervention effect In Fujiminori, grain weight per panicle remained unchanged as irregularity in plant disposition increased.
Association In Manryo, grain weight per panicle increased.
Association In Manryo, the number of panicles decreased.
Intervention effect In plots of cv 30∼100 %, no decrease of grain weight was observed relative to the plot of cv 0 %.
