Description
  • Low R:FR, which is the signal of presence of neighbouring plant, resulted in reduced tillering and stimulated shoot elongation of Festuca rubra grass. In some clones, low R:FR ratios stimulated extravaginal tillering . The origin of the clones (i.e. community type) explained a part of this variation in morphological parameters, but did not explain variation in the response to R:FR levels. Evidence for a consistent relationship between clone performance and radiation environment in the micro-sites where the clones originated from was not found. It seems that there is only limited selection of F. rubra clones (ecotypes) specialised for particular community types and no selection of clones specialised for particular micro-sites within communities.

  • Snížený poměr red:far-red, který slouží jako signál přítomnosti sousedních rostlin, měl za následek útlum odnožování a zvýšené prodlužování listů trávy Festuca rubra. U některých klonů došlo k zesílenému extravaginálnímu odnožování. Jednotlivé klony se lišily svou reakcí. Rozdíly v morfologických parametrech klonů lze částečně vysvětlit původem klonů v různých porostech. Totéž však nelze řící o rozdílech v růstové odpovědi na snížení red:far-red. Nepodařilo se prokázat souvislost mezi projevy klonů a radiačními podmínkami na přesném jich původu. Zdá se, že je pouze omezená selekce klonů typických pro jednotlivá mikrostanoviště (cs)
