Distribution of non-structural carbohydrates in the vegetative organs of upland rice

ABSTRACT Rice is one of the main foods consumed by half world’s population. The rice crop requires plenty water, but upland cultivated in a non-flooded environment, although its productivity lower than that lowland rice. grains mostly consist starch, which synthesized from non-structural carbohydrates imported vegetative organs. long-term storage plays remarkable role maintaining supply photoassimilates during grain filling if photosynthesis does not meet energy demand. Therefore, dynamics central to crops. present study aimed determine carbohydrate content and soluble profiles different organs genotype BRS Esmeralda. was determined at end development. identification quantification were performed high-performance anion-exchange chromatography with pulsed amperometric detection. Fully expanded leaf blades, expanding stems exhibited 59.7, 53.3, 52.3 mg g-1 DM, respectively. stem found be organ for carbohydrates, wherein starch 36.1 DM. It also contained such as glucose, fructose, sucrose. low amounts roots, showing this store carbohydrates.
