Table 1 Results of linear models examining the effects of the year, tree health status, the interaction of them, and tree height on leaf and root concentrations of non-structural carbohydrates (NSC), starch, and sugars in Araucaria araucana during a dry (2016) and a relatively less dry year (2017). F stands for F-ratios, subindices stand for the degree of freedom of the numerator and the denominator, respectively, and number in parentheses show P-values

From: No carbon shortage in declining trees of the isohydric species Araucaria araucana (Molina) K. Koch under drought
