| Abstract:
Fruit yield and growth flushes as well as normal development of the permanent structures of the tree require energy and carbon building blocks. The role of starch reserves in supplementing these requirements is of vital importance. The purpose of this study was to determine to what extent and when starch is accumulated in the "Sensation" mango tree and in its different parts and when it is utilized during the important phenological phases. In addition the role of the various plant parts with regard to their storage and utilization capabilities are examined. Results illustrate that the roots, wood, bark, shoots and even the leaves accumulate starch during the winter and that these reserves are then drastically depleted during the spring and summer. The fruit is a strong sink for starch and dominates all other parts during their development until harvest. | |
