Baris 7: Dampak hipoksia tersebut merangsang bagian tubuh tumbuhan yang tergenang untuk mematikan sebagian sel-sel [[parenkima]] sehingga terbentuklah rongga-rongga dalam jaringan. Rendahnya oksigen juga mendorong tumbuhan membentuk gas etilena<ref>Kozlowski, T. T. (ed.) 1984. Flooding and Plant Growth.

This allows plants to grow without incurring the metabolic costs of anaerobic respiration.<ref>Laing, H. E. 1940. Respiration of the rhizomes of Nuphar advenum and other water plants. American Journal of Botany 27: 574–81.</ref> Some of the oxygen transported through the aerenchyma leaks through root pores into the surrounding soil. The resulting small [[rhizosphere]] of oxygenated soil around individual roots support microorganisms that prevent the influx of potentially toxic soil components such as [[sulfide]], [[iron]], and [[manganese]]. --> == Lihat pula ==
