The relation between the proline content and the K+ efflux may change among species and maturity of leaves. In general, the content of proline in the mature leaves was higher than that in the old leaves and the K+ efflux of the old leaves was higher than that of mature leaves, Spraying proline had a protective effect against sulfurous acid insult. %U https://www.plant-ecology.com/EN/abstract/article_5340.shtml
