In this study, we used a macrophyte model to describe the growth production and the interaction between above‐ and below‐ground organs of P otamogeton pectinatus in L ake B urullus, E gypt. Above‐ and below‐ground biomass of P . pectinatus was sampled on a monthly basis from April to December 2011 at three sites of L ake B urullus. Shoots started to grow in April, reached the maximum biomass in September and then rapidly decreased in October when they moved into the senescence stage. Tubers biomass reduced in August due to the upward translocation to shoots, but sharply increased to the maximum in October by downward translocation from shoots and roots. P otamogeton pectinatus allocated approximately 82.3% of its total biomass to shoots, 15.5% to tubers and 2.2% to roots.
