F statistics (with probabilities) for a two‐way ANOVA testing the effects of the number of days from the start of shoot emergence to harvesting (Harvest, H), light conditions (Light, L), and their interaction, on dry mass (total, shoot and root), the percentage of cotyledon dry mass in dry mass at sowing (estimated from fresh mass), TNC concentrations in cotyledons and roots, and TNC pools in cotyledons and roots of the seedlings in 1999
