Genetic Variation and Spatial Geographical Trend of Needles,Cones and Seeds Traits for Natural Populations of Picea linzhinesis

  • Received Date: 2011-01-04
  • Based on field investigations and analysis of whole natural distribution of Picea linzhinensis, three cone characters, three needle traits and three seed wing characters of 15-30 trees from each of 11 populations in Tibet were selected and measured, in order to make clear population genetic differentiation within the species by statistical analysis. The results showed that it was significantly different in genetic variation among populations and among individuals within populations. The mean phenotypic differentiation among populations (VST) was 29.55%, that was at middle level in spruce species. The variation within populations was the main part of phenotypic variation, which stood 70.45%. The special variation of phenotypic traits within populations was studied by variation coefficient (CV),it showed that the mean CV of three variation indications of needle, cone, and seed wing at species level were 20.39%, 15.65%, and 10.79% respectively, and the variation indication of needle was the highest. By studying Mean CV of 9 phenotypic traits in 11 natural populations, the CV in Jindonggou of Langxian County was the highest, where has the most abundant diversity. Furthermore, The correlations between nine phenotypic traits and location factors and climate factors was analyzed, the results showed that in geographical distribution, the needle length and cone diameter became longer and wider from west to east; and in the influence of climate, the crown diameter, needle length, and needle shape became wider, longer and the more stretched-out with annual mean temperature rising. The 11 populations of P. linzhinensis investigated could be divided into four groups according to the cluster analysis.

The mean phenotypic differentiation among populations (VST) was 29.55%, that was at middle level in spruce species. The variation within populations was the main part of phenotypic variation, which stood 70.45%. The special variation of phenotypic traits within populations was studied by variation coefficient (CV),it showed that the mean CV of three variation indications of needle, cone, and seed wing at species level were 20.39%, 15.65%, and 10.79% respectively, and the variation indication of needle was the highest.

Furthermore, The correlations between nine phenotypic traits and location factors and climate factors was analyzed, the results showed that in geographical distribution, the needle length and cone diameter became longer and wider from west to east; and in the influence of climate, the crown diameter, needle length, and needle shape became wider, longer and the more stretched-out with annual mean temperature rising.
