Analysis of variance of the fixed effects on the biochemical variables at the leaf level in nine genotypes of <i>Hevea brasiliensis</i> from the ECC-1 selection and the IAN 873 cultivar (control) across two seasonal periods and two sites with different climates in Caquetá (northwestern Colombian Amazon).

Season (S), Location (L), genotype (G), and their interactions in chlorophyll a, b (Chl a; Chl b) (mg g-1), carotenoids (Car) (mg g-1), total chlorophyll (Chl total) (mg g-1), proline (μg g-1), catalase activity (CAT) (Ucat/mg protein), reducing sugars (μg mg-1), total sugars (μg g-1), protein (mg g-1), and malondialdehyde (MDA) (nmol ml-1).
