Photosynthetic characteristics of three ploidy levels of Allium oleraceum L. (Amaryllidaceae) differing in ecological amplitude

Popis výsledku v původním jazyce

To elucidate the mechanisms of the adaptive advantages of polyploidy, there is a need to identify physiological traits that participate in the success of polyploids. We studied selected photosynthetic characteristics, stomatal density, and specific leafarea of three ploidy levels (2n = 4x, 5x, 6x) of the geophyte Allium oleraceum that partially differ in their ecological niches. Although the cytotypes were on average similar with regard to most of the measured photosynthetic traits, the hexaploids showed more rapid initial photosynthetic induction and a tendency for a higher maximum photosynthetic rate per unit area. The stomatal density was not affected by ploidy, though the specific leaf area was reduced for the hexaploids compared to the other cytotypes. A lower intracytotype variation was found for most of the studied photosynthetic and anatomical traits for the hexaploids compared to the large variation found within other cytotypes. A comparison of the photosynthetic traits betwe
