The corns were cultured with cross linked polyacrylate amine(CPA) added and arbuscular fungi(AM fungi) inoculated into culture medium,respectively,to study their influence on growth,nutrient uptake and some physiological indices of corn seedlings.The results showed in the medium without CPA the biomass,the content and absorption of phosphorus,the activities of nitrate were improved by fungal inoculation.In the medium with CPA the content and absorption of phosphorus,the biomass of corn were improved while t...
