چکیده

The mechanism and complexity of phloem function was investigated using two angiosperm taxa; Terminalia catappa and Cocos nucifera. The two terminalia plants (A and B) were differentiated by girdling and removing the basal twigs of A, girdling, defoliating and leaving the basal twigs in B. Cocos nucifera (c) was also girdled leaving D as control. After three months, specimen B produced new leaves at the stups. A wilted and withered while C was still flourishing with fruits. After the experimental period of six months, A withered, B whithered and C remained fresh and green. These findings are discussed in line with modern research findings.
