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. 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. 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. H3 is the standard house timber and this grade is used for fence palings. 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. It had been used in The wood is normally kiln dried to 12% moisture in 6 m (19 ft 8 in) long, clear lengths. The plant health- and growth-promoting biological inoculant (bio-inoculant) Trichoderma hamatumLU592 was transformed with the constitutively expressed green fluorescent protein (gfp) and hygromycin B resistance (hph) genes to specifically monitor the isolate in the root system of Pinus radiata within a strong indigenous Trichoderma population. 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. In designing agroforestry systems, the combination of tree genotype (orspecies) and pasture species and the spatial arrangement of trees are importantconsiderations. Due to steep slopes and intense rainfall, the silviculture of Pinus radiata forests is important to control erosion and slope stability. Coarse root CSA growth patterns were similar to that of the fine roots. A green fluorescent protein (GFP)-tagged F. circinatum isolate, together with confocal microscopy, was used in order to monitor the events associated with root infection of Pinus radiata seedlings. Abstract.
Pinus radiata is widely cultivated in New Zealand. Bio-engineering traits such as root distribution and root tensile strength are fundamental to understand the effectiveness of Pinus radiata. It is native to three very limited areas located in Santa Cruz, Monterey Peninsula, and San Luis Obispo Counties. The name applied to this treatment is tanalized wood. Understanding the dynamics and distribution of root system components and how they are affected by pasture–tree interactions in silvopastoral systems are important for better management of agroforestry systems. H4 and H5 are the standard for inground use.
The overall aim of this study was to understand better the ecological behaviour of Trichoderma bio-inoculants in the root system of commercially grown Pinus radiata seedlings.
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. We characterized a Pinus radiata D. Don putative ortholog to the Arabidopsis thaliana (L.) Heynh.SHORT-ROOT gene (AtSHR) and analyzed its expression in different organs during vegetative development and in response to exogenous auxin during adventitious rooting.The predicted protein sequence contained domains characteristic of the GRAS protein family and showed a strong … The biomass and morphology of coarse It was It is available treated with a range of chemical salts, or untreated.
Summary. H1 and H2 treatment is suited to indoor use. Its silviculture reflects a century of research, observation and practice. It is also found as the In Australia, New Zealand, and Spain it is the leading introduced treeThe modern tree is vastly different from the native tree of Monterey.In South Africa, the tree is a threat to already scarce water resources.Use of pine in construction did not become widespread until forced by wartime shortages.

Periodic in situ growth of coarse root (52 mm diameter) diameter was also recorded over the same period. Greater soil moisture content at the 10–30 cm depth in any of the treatments resulted in significantly greater fine root tip initiation and elongation compared with the 0–10 cm depth. 328 p. cited in harvnb error: no target: CITEREFMcDonaldLaacke1990 ( Pine root infection by Fusarium circinatum has been reported in the literature, but the underlying pathogenic interac-tion is poorly understood.
