Abscisic acid (ABA) Analogs Improve Drought Stress Tolerance of Transplants Pumpkins and Tomatoes (1998) - 2 pages
Drought and transplanting shock are common causes of loss during the establishment of horticultural crops such as vegetables, ornamentals and flowering annuals. Application of abscisic acid (ABA) to young seedlings or transplants can increase their tolerance to drought stress and cold. Unfortunately, the beneficial effects of ABA applied in this way are short-lived as the chemical is rapidly metabolized.
PBI/NRC has generated ABA analogs which are more physiologically active and longer-lasting than standard ABA. This research program tested several ABA analogs for use in preventing drought stress in vegetable transplants.
