Rezumat
Regiunile alpine sunt caracterizate de conditii de mediu particulare cum sunt temperaturile extreme,
altitudini mari, cantitatea redusa de nutrimente din sol si perioada scurta de vegetatie. Chiar daca pentru un
numar mare de specii, conditiile amintite sunt restrictive, vegetatia alpina contine un numar mare de specii rare,
relicte si endemice. Saponaria pumilio (L.) Fenzl. Ex. A. Braun este un relict tertiar care vegeteaza in pajistile
alpine din Alpii Estici si Carpatii de Sud. Ca o urmare a adaptarii la mediul alpin, S. pumilio detine caracteristici
specifice acestuia: tulpini scurte, flori mari, frunze dispuse dupa un unghi ascutit, formand pernite. In acest
context, scopul acestei lucrari consta in prezentarea unor strategii de crestere pe care le dezvolta aceasta specie
in ecosistemele in care traieste.
Abstract
The alpine regions are characterized by particular environmental conditions such as extreme
temperature, high altitude, soils poor in nutrients, short vegetation period. Although for many species these
conditions are particularly restrictive, alpine vegetation contains a large number of rare, relict and endemic
species. Saponaria pumilio (L.) Fenzl. Ex. A. Braun is a tertiary relict which vegetates in alpine meadows from
Eastern Alps and South Carpathian Mountains. As a result of adaptations to alpine environment, S. pumilio has
specific characteristics: short stalks, large flowers, leave arrangement in acute angle and it forms cushions. In
this context, the purpose of this paper was to reveal some growth strategies that S. pumilio developed in the
ecosystems in which it lives.
