Variation in Traits of Picea likiangensis var. linzhiensis Seedlings from Different Provenances

  • Received Date: 2013-12-10
  • In order to understand the variation in main growth traits of Picea likiangensis var. linzhiensis at seedling stage, eight seedling traits from 9 provenances in its natural distribution ranges were examined using field seed origin experiment. The results indicated: (1) Except for the lateral root number, the other seven seedling growth traits among 9 provenances showed significant differences; (2) The correlation analysis showed that the seedling height, basal diameter and aboveground biomass were significantly positive-correlated with the longitude, and significant negative-correlated with the altitude, but not significant correlated with the latitude. Interestingly, the taproot length and root/shoot ratio were significant negative-correlated with the longitude. These results suggested that there was a significant provenance geographical variation trend in Picea likiangensis var. linzhiensis at seedling stage; (3) By cluster analysis, the 9 provenances tested could be divided into two geographical provenance groups, the eastern group and the western group. The western group had higher adaptation to drought and cooling, although the increment of eastern group was higher in seedling stage.

Abstract: In order to understand the variation in main growth traits of Picea likiangensis var. linzhiensis at seedling stage, eight seedling traits from 9 provenances in its natural distribution ranges were examined using field seed origin experiment. The results indicated: (1) Except for the lateral root number, the other seven seedling growth traits among 9 provenances showed significant differences; (2) The correlation analysis showed that the seedling height, basal diameter and aboveground biomass were significantly positive-correlated with the longitude, and significant negative-correlated with the altitude, but not significant correlated with the latitude. Interestingly, the taproot length and root/shoot ratio were significant negative-correlated with the longitude. These results suggested that there was a significant provenance geographical variation trend in Picea likiangensis var. linzhiensis at seedling stage; (3) By cluster analysis, the 9 provenances tested could be divided into two geographical provenance groups, the eastern group and the western group. The western group had higher adaptation to drought and cooling, although the increment of eastern group was higher in seedling stage.
