Significance (P-values) of two-way analysis of variance.

Effects of the factors: irrigation (Atocha versus Escalonilla), leaf age/formation (C+0/2011, C+1/2010, C+2/2009, C+3/2008) and month on stomatal conductance (gs) and their interactions during spring with little irrigation (February to April) and summer with irrigation (May to October), ns not significant p≥0.05.
