Abstract:

Abstract：High performance liquid chromatography was used to analyze the changes of endogenous polyamines and salicylic acid content in sisal hemp with different fertilizer treating. The results showed that during the sisal hemp seedling development stage, the reactive of endogenous polyamines to different fertilizers was mainly reflected in the content of endogenous putrescence. Meanwhile, endogenous polyamines and salicylic acid both varied in the seedling period which probably infected by the need of fertilizer with sisal hemp growth.
