Description
  • Young plants of sugar beet, the Elán variety, exposed to progressive drying-up of soil, retained a high RWC > 80 % for a period ranging from 72 to 144 hours from interruption of irrigation. However, stomatal limitation of gas exchanges occurred in them and the photosynthesis rate (PN) and transpiration rate (E) decreased. The abscisic acid (ABA) applied 72 hours after interruption of irrigation improved the plants' water management on the drying-up soil – the plants initially responded to a leaf spray with the concentration of 100 nM by even more closing their stomata and by decreasing PN and E. This slowed down the progression of water stress in the treated plants and, later on, this resulted in higher levels of PN and E and in their better ratio (PN/E) than in untreated plants. Benzylaminopurine (BAP) applied by spraying in the concentration of 1 nM or 10 nM resulted in a highly significant increase of PN and E as early as 2 hours after application.
