Abscisic Acid Analogs Reduce Planting Stress in Newly Planted Seedlings
Steven C. Grossnickle and Raymund S. Folk
1994: Moscow, ID
A research program examined whether specific abscisic acid (ABA) analogs could maintain good water balance of interior spruce seedlings under environmentally stressful conditions, through partial stomatal closure. In addition, the influence of ABA analogs on root growth under optimum conditions was monitored. ABA analogs allowed seedlings to maintain good seedling water balance for extended periods of time, under moderate and severe drought conditions, through greater stomatal closure. ABA analogs caused partial stomatal closure for periods of up to two weeks. Seedlings treated with ABA analogs had the capability to grow an extensive number of new roots, when tested under optimum environment.
