KINETICS RESEARCH ON TRANSPORTATION AND DISTRIBUTION OF PHOTOSYNTHATE IN VARIOUS SPECIES OF COTTON LEAVES |
| |
| Abstract: | The dynamic model of assimilate partition was established by using radioisotopes tracing technique in vivo and measuring transportation and distribution of photosynthate in various species of cotton leaves.Analysing relevant coefficient showed that (1) the amount of the photosynthate transportation among the various compartmentations of cotton leaves in Simian No.3 were higher than those in Gossypium barbardense L.evidently,so was the photosynthate transportation rate from apoplast to phloem,regardless of day or night. |
