Adaptation of cucumber seedlings to low temperature stress by reducing nitrate to ammonium during it's transportation.

ABSTRACT:

Background

Low temperature severely depresses the uptake, translocation from the root to the shoot, and metabolism of nitrate and ammonium in thermophilic plants such as cucumber (Cucumis sativus). Plant growth is inhibited accordingly. However, the availability of information on the effects of low temperature on nitrogen transport remains limited.

Results

Using non-invasive micro-test technology, the net nitrate (NO₃^-) and ammonium (NH₄⁺) fluxes in the root hair zone and vascular bundles of the primary root, stem, petiole, midrib, lateral vein, and shoot tip of cucumber seedlings under normal temperature (NT; 26 °C) and low temperature (LT; 8 °C) treatment were analyzed. Under LT treatment, the net NO₃^- flux
