RELATIONSHIP OF ENDOGENOUS HORMONES, POLYAMINES AND SALICYLIC ACID CONTENTS WITH RHIZOME ENLARGEMENT OF LOTUS (NELUMBO NUCIFERA GAERTN)
Using high performance liquid chromatography, the changes of endogenous hormones, polyamines, and salicylic acid content in 3 lotus cultivars rhizomes were studied. The results showed that the peak of zeatin content appeared at the 1 internode stage and first internode of 3 internode stage rhizome. Gibberellin, indole-3-acetic acid and salicylic acid content increased quickly from the 1 and 2 internode stage, respectively; and all reached their highest levels at the 3 internode stage; furthermore, indole-3-acetic acid content was significantly correlated with salicylic acid at 0.01 level during rhizome development. Abscisic acid content in the first internode was higher than that in the second and third internodes of 3 internode stage rhizomes, and it increased rapidly in the end stage of rhizome enlargement. Spermine and putrescine content were significantly higher than cadavarine and spermidine during rhizome enlargement.
