Abstract

ORIG CZ

V originále

- Background and Aims: We tested whether the local differences in genome size recorded earlier in the wild barley, Hordeum spontaneum, at 'Evolution Canyon', Mount Carmel, Israel, can also be found in other organisms. As a model species for our test we chose the evergreen carob tree, Ceratonia siliqua. - Methods: Genome size was measured by means of DAPI flow cytometry. - Key Results: In adults, significantly more DNA was recorded in trees growing on the more illuminated, warmer, drier, microclimatically more fluctuating 'African' south-facing slope than in trees on the opposite, less illuminated, cooler and more humid, 'European' north-facing slope in spite of an interslope distance of only 100 m at the canyon bottom and 400 m at the top. The amount of DNA was significantly negatively correlated with leaf length and tree circumference. In seedlings, interslope differences in the amount of genome DNA were not found. In addition, the first cases of triploidy and tetraploidy were found in C. siliqua. - Conclusions: The data on C. siliqua at 'Evolution Canyon' showed that local variability in the C-value exists in this species and that ecological stress might be a strong evolutionary driving force in shaping the amount of DNA.

In Czech

Mikrogeografická diferenciace velikosti genomu u Ceratonia siliqua v Evolution Canyon v Izraeli. Vliv sexu na velikost genomu neprokázán (hormonálně determinované pohlaví). Objeveny nové cytotypy 3x a 4x. Negativní korelace s velikostí listů a s průměrem kmene. Pozitivní korelace s průměrnou roční teplotou. Negativní korelace ročním úhrnem srážek.
