Abstract
The article presents the results of the study of the interaction "genotype-environment» (GEI) in the 38-41-year-old provenance tests of Siberian pine and Korean pine on the two hypsometric levels on the northern slope of Ukrainian Carpathians. The provenance tests were established on 2 sites in the state arboretum "Visokogirny" (altitude 1150-1280 m) and in the state arboretum "Dibrova" (altitude 300 m). One of the GEI options, namely the interaction of "provenances- environment", was evaluated by the average deviation methods rank according A.C. Matheson, C. A. Raymond and Spearman's rank correlation coefficient. Certain rank deviations of provenances Siberian stone pine for average height were identified (the average rank deviation from the average across-site rankings equals 1,6). Among all proved 15 provenances five provenance changed their place in the ranking for this trait by 5 positions and more. As deduced 7 provenances changed their ranks for height slightly (the average deviations of the ranks were 0,5-1,0). Spearman's rank correlation coefficient between the ranks of provenance of Siberian stone pine for the height equals 0,60 and is significant at the 5% level. The ranks of provenances Siberian stone pine for diameter at breast height (DBH) vary much more. Spearman's rank correlation coefficient for this trait equals 0.44, but it is insignificant even at the 5% significance level. To a great extent interaction "genotype-environment" for Siberian stone pine was established for the current annual height increment (12 from 15 provenance changed rank on 3 position and more, the average rank deviation from the average across-site rankings equals 2.9, Spearman's rank correlation coefficient is close by 0). Thus the results indicated that the interaction for Siberian stone pine is apparent for the current increment in height, some less for the average total height and the average diameter of the trunk at breast height. Among Siberian stone pine provenances were identified particularly sensitive to changes in environmental conditions progeny of populations (№ 2279, 2293, 2295) and less interactive with conditions of test sites provenance (№ 2281, 2284, 2289). Owing to the small number of Korean pine proveniences that are tested we can only suppose about certain trends in the magnitude of their interaction with the site conditions. In contrast to the previous species GEI for Korean pine is more noticeable for the height means of provenances and less clear for the current annual height increment.
