manipulating of planting pattern is a method to increase the crop yield per unit of area which should be considered in different regions. in order to evaluate the effects of between and within row distances on growth indices of gahar mung bean, an experiment was conducted at the agricultural research center of ilam in 2004. the experiment was a split-plot arranged in an rcb design.three between...

Quality control sampling in post-thinning assessments at Kaingaroa Forest Chong, Sing-Lai Effect of moisture content on retention of copper-chrome-arsenate preservative in radiata pine sapwood created by vacuum pressure method Dale, R.W. A study of root and needle distribution patterns in 6 year old P. radiata at Eyrewell Forest Deadman, H.W. Farmers' attitudes towards planting tree...

The pitch canker fungus Fusarium circinatum was first associated with mortality of P. radiata in California during the 1980s. Since then it has been dispersed to several countries of the Northern hemisphere together with South Africa and Chile in the southern hemisphere. In Chile the disease caused mortality of seedlings in P. radiata at nursery, and in South Africa the pathogen has already com...

The overall aim of our research is to eventually develop a viable system, using pinus radiata, for multi-storey timber buildings up to 6 storeys. One of the main issues is achieving sound resistant timber floors that are economically viable. This paper reports on the acoustic testing of a prototype floor, with radiata pole joists. Measurements were made of the objective performance. The results...

Radiata pine (Pinus radiata) lumber from Australia, Chile, and New Zealand is imported into Korea where it represents one of the most important sources of timber. Blue stain of this timber is a serious problem for which an integrated control strategy is being developed. One of the fungi that has been isolated from stained radiata pine sapwood in Korea is a Leptographium sp. that has a distinct ...

Gas exchange was measured on a pruned Pinus radiata D. Don hedge and on a long-branch P. radiata tree near Hamilton, New Zealand, in spring 1993 when soil water content was close to field capacity. Foliage at the end of long branches (9.0 m) showed a marked drop in net photosynthetic rate and stomatal conductance as the saturation deficit increased, whereas foliage on short branches (0.5 m) sho...
