Synopsis

In response to long-term oxygen shortage in the rooting medium (>7days), there was an accumulation of soluble carbohydrates in shoots as well as in roots of wheat seedlings (Triticum aestivum L. cv. Alcedo). The content of fructo-oligosaccharides had increased five-fold in the roots and seven-fold in the shoots. This fails to fit the assumption that higher substrate consumption is accompanied by the fermentation under oxygen shortage.
