Abstract

It is known that there is a relation between the biotic and abiotic environment and that this interaction reflects in the live organisms group of a place. The interactions between genotype and environment, also already recognized, act in a anolog way, but in a difficult mensurable constatation. In this way, the current research objectives relating soil Chemistry characteristics with the heterozygotics levels of three Xylopia emarginata Mart. subpopulations. The generic analysis results demonstrated that the subpopulation 1 differs from other ones, showing significative Wright fixation index (-0.389), while non-significative values have been found in the subpopulations 2 and 3 (-0.105 and -0.209, respectely). This difference has also been observed by the Principal Component Analysis (PCA), where the subpopulation 1 has been influencianted by the tenors of organic material (MO), alumin (Al), effective cationic change capacity (t), pH 7.0 (T) and sum of hydrogen and alumin (H+Al), while the subpopulations 2 and 3 have been influenciated by pH, phosphor (P) and basis saturation index (V). In the same way, the allele 2 of EST-1 andMDH-2 are inversely related to pH, P and V end the allele 1 of GDH-3, SDH-3 and GTDH-3 directly related with MO, AL, t, T and H+Al. In studied populations of Xylopia emarginata Mart. the soil chemistry characteristics affected heterozygotics levels.
