The measurement involved a large amount of 7-day seedlings (over 100 pcs). The composition of the seeds was evaluated for seeds with a seed coats.

Increase - bold digits, decrease - italicized digits. Trivalent elements marked with (III). Labels: SSOIL/SEEDS - relative content for seedlings growing in soil compared to seed composition, SPAPER/SEEDS - Relative content for seedlings growing on blotting paper compared to seed composition, SSOLI/PAPER - Relative content for seedlings growing in soil and on paper. Statistical significance: S - for the relation between seedlings and seeds, P - for relation between seedlings grown on paper and seeds, C - for relation between seedlings grown in soil and seedlings grown on paper, X - no data for determining the relationship, n.d. – not detected.
