aab12104-sup-0001-TableS1.docWord document30KTable S1. Preliminary experiment to detect light response in fresh achenes of five wild biotypes of Helianthus annuus. The experiment was conducted as a randomised complete design with three replicates and experimental units of 25 achenes. Data were analysed by ANOVA, within each biotype, after logit transformation considering light (with or without light) as source of variation

aab12104-sup-0003-TableS3.docWord document36KTable S3. Germination (%) of 12-months stored achenes of five invasive H. annuus biotypes (wild) and their progenies with a sunflower cultivar (F1) with different treatments (T). Treatments were cold stratification (CE); gibberellic acid 1 mM (GA); mechanical scarification (MS) and control (No). LSD: least significant difference (P = 0.05), d.f. = 12. Statistics (F) with their respective P-value are shown
