(a) Photograph of leaves, (b) area of leaves, (c) rate of photosynthesis and (d) stomatal conductance of third trifoliate leaves of soybean plants emerged after pre-treatment of seeds with different SMF strengths (0–300 mT). The error bars indicate ±standard error for the mean. The values presented are significantly different at (**P < 0.01,***P < 0.001) from untreated seeds (Newman–Keulis multiple comparison test). |
