Characterization of ammonium and nitrate uptake and assimilation in roots of tea plants

Abstract:

It has been pointed out that tea (Camellia sinensis (L.) O. Kuntze) prefers ammonium (NH4+) over nitrate (NO3-) as an inorganic nitrogen (N) source. 15N studies were conducted using hydroponically grown tea plants to clarify the characteristics of uptake and assimilation of NH4+ and NO3- by tea roots. The total 15N was detected, and kinetic parameters were calculated after feeding 15NH4+ or 15NO3- to tea plants. The process of N assimilation was studied by monitoring the dynamic 15N abundance...
