The Correlation Analysis Between Yield Traits and Growth Traits of Agarwood

Measuring the diameter at breast height (DBH), chcanopy, density of wood, agarwood formation rate, oil content and other traits after the individual process of artificial agarwood inducing 6 years aloes plants of Vietnam and Huazhou.Correlation analysis between yield traits and growth traits of agarwood has been developed based on the measured results.There were no significant differences between individuals of growth traits.However, there have significant differences of yield traits between individuals.Moreover, height and DBH of Vietnam samples were higher than that of Huazhou samples.Dry weight of the section agarwood (DWA) and oil yield (OY) of Vietnam samples were significantly higher than that of Huazhou samples.The multiple linear model between tree crown volume (CV) and DBH and OY and DWA were OY=T-0.111+0.004*CV+0.010*DBH and DW=-0.802+0.23*CV+0.72*DBH, respectively.The S function regression model between DW and OY and DBH were DW=exp (3.705-74.239/DBH), OY=exp (2.297-83.3/DBH), respectively.Results indicates that they have a significant positive correlation or high significant positive correlation between yield traits and growth traits of agarwood, and they have a high individual yield of agarwood with rapid growth properties and high formation abilities.
