ABSTRACT

The study of the characteristics that differentiate to the source tissues (mature leaves) from the sink tissues (seeds, flowers, roots, young leaves, tubers, etc) and of the relations among them, it has opened the possibility to modify the distribution of photosynthates in cultives of commercial interest. The pathway in which they are loaded and unloaded from the phloem (routes symplastic and apoplastic) is one of the factors that defines the amount of sugars that are exported from the source tissues towards sink tissues. However, the magnitude of the flows of carbon is subject to a very complex regulation in which internal elements and environmental factors participate as a whole, allowing that the distribution of the photosynthates can adjust to satisfy the physiological necessities of each organ in response to its development and to changes in the environment.
