Abstract:
The effects of REE on growth of wheat coleoptiles, IAA oxidase activity, peroxidase isoenzyme, endogenous IAA levels were tudied. The results Showed that REE promoted the growth of wheat coleoptiles from 100ppm to 1000ppm, especialy at 1000ppm, accompanying with the increase of IAA oxidase activity and the number of peroxidase isoenzyme band, and decrease of endogenous IAA content decreased. REE also enhanced the exogenous IAA on promotion of wheat coleoptile growth and eliminated the inhibition effect of exogenous ABA on coleoptile growth.
