The main constraint on rice cultivation in the Mediterranean area is the limited irrigation and its large water consumption. In addition, rice is very sensitive to drought conditions because of drought stress on morpho-physiological traits and yield reduction. The application of salicylic acid (SA) has been noticed to be very effective in alleviati...

Barley (Hordeum vulgare L.) is one of the Neolithic founder crops of Old World agriculture. It is a flowering plant belonging to the family Poaceae or Gramineae (herbs) that is cultivated in temperate climates across the world at 350–4050 m above sea level, and evolved from H. spontaneum (K. Koch) Thell. The economically most important species of t...
