Insect-resistant transgenic Pinus radiata.

Abstract: Transgenic radiata pine (Pinus radiata D. Don) plants containing a Bacillus thuringiensis (Bt) toxin gene, crylAc, were produced by means of biolistic transformation of embryogenic tissue. Using the selectable marker gene nptII and corresponding geneticin selection, 20 independent transgenic lines from five genotypes were established. Over 200 plants regenerated from ten transgenic lines were successfully transferred to soil. The integration and expression of the introduced genes in transgenic tissue and/or plants were confirmed by PCR, Southern hybridisation and neomycin phosphotransferase II (NPTII) and Bt ELISA assays. Bioassays with larvae of the painted apple moth, Teia anartoides, demonstrated that transgenic plants displayed variable levels of resistance to insect damage, with one transgenic line being highly resistant to feeding damage.

Adhesion of spray droplets to foliage: The role of dynamic surface tension and advantages of organosilicone surfactants†

Abstract: Measurements of the dynamic surface tension of seven surfactants (four organosilicones, two «conventional» hydrocarbon-based surfactants and an organosilicone+hydrocarbon-based blend; 0.5 to 5.0 g litre -1 ) have been combined with data on the adhesion of their spray droplets to pea leaf. The latter were determined by a method enabling the surface age, and thus surface tension of the droplets at impact, to be calculated. Adhesion was directly related to the dynamic reduction in surface tension (2 to 50 mN m -1 ) prior to impact. The organosilicone surfactants and the blend reduced surface tension more rapidly and to lower values than did the organic surfactants

Biological flora of New Zealand 9. Beilschmiedia tawa(A. Cunn.) Benth. et Hook. F. ex Kirk (Lauraceae) Tawa

Abstract: Morphological and anatomical descriptions of Beilschmiedia tawa are given together with information relevant to its ecology, a distribution map based on its presence or absence in grid squares, and bibliographic references to other informaion. B. tawa is one of the main canopy-forming trees in the lowland and low hill forests of the North Island and is also one of the main merchantable hardwoods. It has a good capacity to regenerate in shade or small canopy gaps, but is sensitive to exposure, tending to deteriorate in intensively logged forests.
