ANATOMY OF STEM AND ROOT WOOD OF PINUS RADIATA D. DON RAJNI N. PATEL Forest Research Institute, New Zealand Forest Service, Rotorua (Received for publication 16 November 1970) ABSTRACT Tracheids are much longer and wider in the root wood than in the stem wood of Pinus radiata D. Don. In New Zealand a 1995 change to no longer require Lower grade timber is converted to pulp to make newsprint.The bark is also used as a substrate for potting and re-potting orchids. The occurrence of the rate maximum of fine root elongation was 8 weeks later for the seedling trees than that of the clonal trees in the no-understorey treatment, whereas in the lucerne treatment the difference was only 4 weeks. In designing agroforestry systems, the combination of tree genotype (orspecies) and pasture species and the spatial arrangement of trees are importantconsiderations. Pinus radiata is widely cultivated in New Zealand. The maximum growth rate of coarse root CSA occurred in early April (autumn) 10–12 weeks earlier in the no understorey than in the lucerne treatment.Present address: School of Resources, Environment and Society, The Australian National University, Canberra, Australia.We use cookies to help provide and enhance our service and tailor content and ads.

The spatial variation of fine root length density (FRLD) ofthree radiata pine (Pinus H3 is the standard house timber and this grade is used for fence palings.

Abstract. 2013. Downloaded on 13 July 2013.Scott, C. W. 1960. It is native to three very limited areas located in Santa Cruz, Monterey Peninsula, and San Luis Obispo Counties. The seasonal patterns of initiation of fine root tip and fine root elongation were studied for a period of 12 months for two genotypes of Fine root tip initiation and elongation, and cross-sectional area (CSA) growth of coarse roots were mainly influenced by differences between the two genotypes and soil moisture stress caused by lucerne competition. Chemical salt treatment is well proven and such timber is frequently used in the ground as posts and poles as part of structures such as retaining walls and pole houses. The maximum rate of fine root tip initiation occurred earlier in the 0–10 cm than in the 10–30 cm depth, whereas the maximum rate of fine root elongation occurred earlier in the latter.The maximum rate of fine root elongation for clonal trees was 35% greater in the no understorey than in the lucerne treatment due to greater soil moisture availability in the former; whereas with the seedling trees it was not different between the understorey treatments. Rome, Italy. Pinus radiata, family Pinaceae, the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico (Guadalupe Island and Cedros island).. P. radiata is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. 328 p. cited in harvnb error: no target: CITEREFMcDonaldLaacke1990 ( H4 and H5 are the standard for inground use. Bio-engineering traits such as root distribution and root tensile strength are fundamental to understand the effectiveness of Pinus radiata. Fine root length density and coarse root biomass and architecture of tissue cultured clonal and seedling planting materials of Pinus radiata D.Don was estimated in an agroforestry system with underst orey treatments (no understorey, Medicago sativa, and Lolium perenne + white clover) at the Lincoln University agroforestry experiment site, New Zealand.
