THE ROLE OF ABSCISIC ACID IN CAUSING LEAF ABSCISSION IN ORNAMENTAL FOLIAGE PLANTS |
| Authors: | J.N. Sacalis, J. Peterson, D. Durkin |
| Abstract:
Factors causing abscission in foliage plants were surveyed. Hydroponics and sand culture of Ficus benjamina, a tropical foliage plant were utilized in an effort to demonstrate a possible relationship between leaf abscission caused by water stress and changes in ABA levels of leaves. Certain inconsistencies in correlation of changes in ABA levels with water stress and abscission suggest that ABA may not be a primary affector of abscission in this species. | |
