metadata.value: Hypoxia is a severe stress factor which negatively affects plant growth. One of
  the adaptations to hypoxia is formation of aerenchyma. Lysigenous aerenchyma
  was found in many species, including barley (Hordeum vulgare L.). At what
  moment of root development and in which part of it the lysigenous cavities are
  formed is not completely clear. For this, barley plants were grown hydroponically
  with and without aeration for 30 and 40 days, respectively. Every 5 days
  seminal roots from barley plants were detached from the seedlings, and were
  divided into 4 equal parts characterizing the age gradient of cells from the apical
  (1) to its base (4) part. Under hypoxic conditions, aerenchyma in barley roots
  was formed in two stages — to the 10th day of growth (1st stage) and to the
  30th day of growth. Lysigenous cavities were mostly formed in the parts with
  the most mature cells (in the 3rd and 4th parts). Accumulation of H2O2 in basal
  part of roots could be considered as a trigger for the aerenchyma formation at
  the first stage, but not at the second one. Aerenchymal lacunae were absent in
  seminal roots of aerated plants.
