(a)–(g) Phase-contrast images of the middle region of leaves of soybean plants emerged after pre-treatment of seeds with different SMF strength (0–300 mT in steps of 50 mT) showing midrib enhancement for 200 mT field strength. The vascular regions (marked with a blue rectangle) near the midrib in the control and 200 mT leaves show an enhancement for the 200 mT leaves. |
