Relation of Increased Potassium Nutrition to Photosynthesis and Translocation of Carbon

摘要: Effects of supplying K+ at 2 or 10 millimolarity concentration on net carbon exchange and translocation products photosynthesis were studied in plants Beta vulgaris L. (var. Klein E). Transport into out leaves was with 42K over a 3-day period. Increasing the supplied to roots from millimolarity, level just sufficient overcome obvious deficiency symptoms, resulted gradual accumulation per unit area an increased export sink regions. No significant increase observed that had accumulated high area. Initiation rate, total area, fresh weight similar for level. Shoot/root ratio dry accumulation, which are indicative partitioning long term, independent supply range. Accumulation by exporting its subsequent recirculation sinks when this range but did not appear affect nutrition even after
