Analysis methods of variance and correlation analysis were used to analyze these data. The following conclusions were obtainedf (1) The difference of growth characters of Juglans mandshurica is relatively significant among provenances, (2) The result of first trial has indicated that Julans mandshurica growth trend expresses two-way gradual change trend with different longitude and latitude, but the second trial has no obvious gradual change trend. Height of Juglans mandshurica is negatively correlated with elevation; (3) The provenance of Shulan. Mao'ershan and Baishishan were selected as superior provenance of afforestational seeds for Mao'ershan and its brink region.展开更多

Height of Juglans mandshurica is negatively correlated with elevation; (3) The provenance of Shulan. Mao'ershan and Baishishan were selected as superior provenance of afforestational seeds for Mao'ershan and its brink region.
