The absorption and distribution of phosphorus in Cymbidium sinense(Andr.)Willdcultured in radioactive phosphorus(NaH2 32PO4)solution were studied.The absorbing abilityof 1-year-old root was stronger than that of 2-year-old root,but the latter still hadrather strong absorption ability, hence good care should be taken in both kinds of rootduring cultivation process.The sequence of accumulation of radioactive phosphorus(cpm/100mgDW) in vegetative groWth period was leaf bud, pseudocorm and leaf, but in reproductive growth period was floral bud, pseudocorm and leaf. This phenomenon coincideswith the rule that nutrient should distribute towards the growth center of plant.
