Development of Weight Variation in Douglas-Fir Seedlings

Coefficients of variation (CV) for weight of seedlings of Douglas-fir in nursery beds increased with age and mean weight of seedlings. The relationship between log10 dry weight and coefficient of variation for weight was linear from seed through 2 + 0 seedling stages. Infection by the fungus Fusarium oxysporum and the nematodes Pratylenchus penetrans and Paratylenchus projectus in unfumigated soil did not noticeably affect this relationship. Variation in relative growth rate was inferred from changes in stem diameters during the second growing season. Such variation would cause a positive correlation between log dry weight and CV. It could be reduced only by treatments that suppress growth or reduce growing time. Forest Sci. 19:105-108.
