In coconut sap, two compounds probably derived from ABA with m3SS spectra consistent with their being clihydrophaseic acid and either hydroxyphaseic acid or oxo-dihydrophaseic acid were also found to be presentenAbscisic acid -Cocos -Phloem exudatecoconutPhloem ExudateAbscisic Acid and Related Compounds in Phloem Exudate of Yucca flaccida Haw. and Coconut (Cocos nucifera L.)Article
