Influence of daylength on gibberellin metabolism and stem growth in Silene armeria.

abstract：MAIN CONCLUSION:Anthocyanins in upper (adaxial) leaf tissues provide greater photoprotection than in lower (abaxial) tissues, but also predispose tissues to increased shade acclimation and, consequently, reduced photosynthetic capacity. Abaxial anthocyanins may be a compromise between these costs/benefits. Plants adapt...
