Effect of Nitrogen Form on Nitrate and Photosynthesis in Coriander

doi:10.7668/hbnxb.2010.02.044

Abstract

Abstract: In order to improve photosynthetic and reduce nitrate content, the paper was conducted under controlled hydroponics to value the influence of nitrogen form on growth and photosynthesis and nitratemetabo lism of coriander( Coriandrum sativum ). The results showed nitrate content, nitrate reductase, net photosyn thetic rate in leaves and biomass increased with the decreasing ratio of NO₃^--N/NH₄⁺-N, when nitrate and ammonium were applied simu ltaneously in so lution. N itrate accumu lated in the root of coriander easily than leaves.

Key words: Nitrogen form, Nitrate, Nitrate reductase, Photosynthesis
