Sažetak
It is well-known that carob tree (Ceratonia siliqua L.) is not overspread in Croatian north Adriatic islands and coast. Moreover, it is hardly possible to find spontaneous (not planted) trees of Ceratonia siliqua northern from the island of Dugi Otok and Zadar coast. However, during the first research year of research project TEUCLIC (acronym for: Taxonomy, Ecology and Utilization of Carob tree and Bay Laurel in Croatia) financed by Croatian Foundation for Science, we found the northernmost habitat of carob tree on the island of Mali Lošinj (basic coordinates: 44.32°N and 14.28°E). This paper deal with the results of morphometric analyses of carob tree pods and seeds of Mali Lošinj population, compared with the same analyses of carob tree population of island of Drvenik Mali placed in middle-Dalmatian archipelago (basic coordinates: 44.45°N and 16.08°E), in order to find the possible differences of most important morphological traits between these two relatively distant populations. After provided morphometric research we found smaller length and thickness of carob pods of population of Mali Lošinj in the comparison with population of Drvenik Mali, but the differences were not significant (D=2.67 and 2.28 ; F-test not significant, p= 0.272 and 0.877, respectively). On the other hand width of carob pods of population of Mali Lošinj were significantly smaller in the comparison with population of Drvenik Mali (D= 8.66, p0.001), as well as weight and average number of seeds per pod (D=15.4 and 2.26, p0.001, respectively). Also, we found that carob seeds of population of Drvenik Mali are significantly longer, wider (D=1.08 and 0.68, p0.001, respectively) and also heavier in the comparison with the population of Mali Lošinj and (D=0.05, p0.05), in spite of the fact that the seeds of population of Mali Lošinj were significantly thicker in the comparison with seeds of Drvenik Mali population (D=0.24, p0.001). The differences between these morphometric traits cannot be explained by environmental conditions, particularly soil conditions. Primarily, because there isn’t significant differences in content of phosphorous and level of soil acidity (pH determined both in distilled water as well as in 1M KCl solution) between these two habitats, with exception of significantly higher potash content in soil samples of Drvenik Mali in the comparison with soil of Mali Lošinj (D=39.48 mg/100 grams of soil). We assume that the differences in morphometric traits of carob pods and seeds between these two populations are primarily caused by genetic factors, which have to be confirmed by the analysis of genomic DNA isolated from the leaves.
