[ 1 ] - Improving Effects of Mild Cold Stress and Salicylic acid on Growth and Physiology of Periwinkle (Catharanthus roseus Don.)

To study effects of salicylic acid (SA) treatments (0, 0.5, 1 and 2 mM) in two forms of seed priming (for 24 h) and spraying on seedling at 4-6 leaf stage an experiment was conducted on periwinkle (Catharanthus roseus Don.) with and without exposure to a mild cold stress of 8 °C (for 32 h).
