Growth and foliar variation among provenances ofEucalyptus camaldulensis Dehn. grown at Dehradun

Abstract

Results of provenance trial ofEucalyptus camaldulensis, established at New Forest, Dehradun, are discussed. Highly significant differences were observed among the provenances for growth (P=0·001) and foliar (P=0·01) characteristics. The provenances of Katherine, NT (S3); Hughendon, Queensland (S7) and Petford, Queensland (S1) from Australia proved best at the site of introduction with mean height 12·97, 13·63 and 12·69 m and mean diameter 10·39, 9·47 and 8·49 cm respectively. Selection of provenances has been advocated on the basis of their comparative performance and within provenance variability. Overall performance of northern and southern populations, having a line of discrimination somewhere between 21°S and 23°S latitude, has been discussed. For the first time statistically significant provenance difference has been explored at stomatal level. Significant negative correlations were obtained between provenance latitude and height (r=−0·64), diameter (r=−0·73) and stomata length (r=0·84). The impact of maximum temperature of the provenance on height and leaf length was observed to be positive and significant (r=0·824 and 0·710 respectively).
