Anchorage of mature conifers: resistive turning moment, root-soil plate geometry and root growth orientation.
Eighty-four mature Norway spruce (Picea abies L. Karst), silver fir (Abies alba Mill) and Scots pine (Pinus sylvestris L.) trees were winched over to determine the maximum resistive turning moment (M(a)) of the root-soil system, the root-soil plate geometry, the azimuthal orientation of root growth, and the occurrence of root rot. The calculation of M(a), based on digital image tracking of stem...

15 صفحه اولFine and coarse root parameters from mature black spruce displaying genetic soil moisture interaction in growth
Fine and coarse root biomass, C, and N mass parameters were assessed by root size and soil depths from soil cores in plots of 32-year-old black spruce (Picea mariana (Mill.) Britton, Sterns & Poggenb.) from four full-sib families studied previously for drought tolerance and differential productivity on a dry and wet site. All fine and coarse root size categories had greater root biomass on the ...
متن کاملRoot orientation of four sorghum cultivars: application to estimate root length density from root counts in soil profiles
The root length density (RLD) distribution in the soil is a key factor for water and nutrient uptake but its direct assessment is not easy. A field method is presented here to assess RLD of sorghum (Sorghum bicolor L. Moench) from the root intersection density (RID) and taking root orientations into account. The method was developed with four varieties cropped in 2006 in Bambey (Senegal) on a s...
متن کاملRoot cold hardiness and native distribution of subalpine conifers
COLEMAN, M.D., HINCKLEY, T.M., MCNAUGHTON, G., and SMIT, B.A. 1992. Root cold hardiness and native distribution of subalpine conifers. Can. J. For. Res. 22: 932-938. Root and needle cold hardiness were compared in seedlings of subalpine conifers to determine if differences existed among species originating from either cold continental climates or mild maritime climates. Ahies amabilis (Dougl.) ...
