摘要
Illuminating shoots stimulates nitrate uptake by wheat (Triticum aestivum L. cv. 'EM18') roots. A method with a high time resolution (minutes), non-invasive technique, has enabled to measure the nitrate uptake time coarsely. The nitrate uptake by wheat roots increases in the light and decreases in the dark. The mechanism is thought to be via a signal carried in phloem, probably a sugar.
