| Title : | VARIABILITY OF TAXODIUM AS A BASE FOR EVALUATION OF ITS GENETIC POTENTIAL IN THE AREA OF GREAT WAR ISLAND |
| Abstract : | The genus Taxodium Rich. was widely located in Europe and North America in the past. Nowadays there are only three species from the southern parts of North America and Mexico: Taxodium ascendens Brogn., Taxodium distichum (L.) Rich. and Taxodium mucronatum Ten. The natural habitats of taxodium are some temporary wet soils in south-eastern part of the USA, from Lousiana to Florida. In Serbia there is mainly Taxodium distichum (L.) Rich. which grows on some wet habitats – there are a number of single trees located on some green surfaces of urban areas. There is a seed plantation in Backa Palanka in the northern part of Serbia. There are some representatives of Taxodium distichum (L.) Rich. on the “The Great War Island” area, too, where a great variability of Bald cypress introduces special genetic potential that includes more than 80 well-adapted genotypes. The evaluation of morphological characteristics variability of twigs and needles was measured on 48 genotypes from the “Great War Island” area. The chosen genotypes belong to the higher diameter and grow outside the influence of some other trees that take sunlight from them. There is a sample consisted of 100 twigs and needles, taken from each genotype, and there were measured length of twigs, and length and width of needles, as well. The data collected on 1440 performed measurements were processed by the computer program Statgraph 6.0, the descriptive statistics, analysis of variance and LSD-test were performed. The Average values of the twigs length are from 69.52 mm to 152.16 mm, of the needles length are from 11.64 mm to 16.69 mm, and finally of needles width from 1.00 mm to 1.49 mm. This values show that there is a significant intra-provenance variability, which introduces a good base for conservation and sustainable using of genetic potential of this rare tree that originates from Serbia. |
