Abstract
When apple (Malus sylvestris Mill) seedlings are fed abscisic acid (ABA), a water soluble complex of ABA and glucose is rapidly formed. This may be a mechanism for inactivating ABA. Similarly, the trans isomer of ABA (trans-ABA) gives rise to a water soluble complex, which is also presumed to be a glucose complex. Apple seedlings did not convert ABA to trans-ABA during feeding experiments, suggesting that small amounts of trans-ABA occasionally found in apple seedling extracts may be artifacts.Keywords
