Summary

The age-related changes of chromosomal instability in seeds of welsh-onion (Allium fistulosum L.), grown in environments with different rate of pollution were studied. Regression analysis of frequency of anaphase cells with chromosome aberration (AA) and number of aberrations per cell with aberations (NApCA) on the age of seeds revealed that these indicators during seeds' storing change by different ways. The most significant growth of AA was noted for seeds from "bad" environment (Vasilkov) - the regression coefficient b = 0,836. Seeds from "good" environment (Vlasivka) had the lowest rate of increasing of AA - b = 0,2274. Seeds from "common" environment (Oster) had the regression coefficient b equal to 0,4637. NApCA also changed by distinct ways: the regression coefficient for seeds from Vasilkiv agripopulation was 0,89, from Vlasivka - 0,16 and from Oster - 0,47. Obtained results let us to prorose the rate of age-related chromosomal instability in seeds as an indicator of ecological welfare.
