Abstract: By using pot tests, the effect of low-P stress on dark sun-cured tobacco endogenous hormone and root activities were studied during different growth stage. The results showed that root activities were decreased, root/shoot ratio and IAA in the root and leaves were high, dry weight and ZR in the root and leaves were low. The high IAA/ZR under P stress promote the root growth, and root /shoot ratio increased. So it can take in more P from soil in to resist unfavorable environment conditions.
