Genetic differences between Pinus halepensis, Pinus brutia and Pinus eldarica based on needle flavonoids

Biochemical Systematics and Ecology, 1997
A chemosystematic study based on needle flavonoids, was carried out on 324 trees from six populations of Pinus halepensis, six of Pinus brutia and one of Pinus eldarica. Two main flavonoid classes were identified and measured by HPLC: (pro)anthocyanins and flavonols.

Selective phytotoxicity of hexazinone to Pinus resinosa and Pinus banksiana

Pesticide Biochemistry and Physiology, 1992
Hexazinone (3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione) is an s-triazine herbicide that is used widely to control weeds in forest plantations and on industrial rights-of-way. Under controlled environmental conditions, red pine (Pinus resinosa Ait.) has been shown to have greater tolerance to hexazinone than jack pine (Pinus

Pine (Pinus radiata)

2006
This chapter describes the transformation of Pinus radiata using organogenic cotyledon explants rather than the more common somatic embryogenesis methods for conifers. The advantages of our method are the year round availability of seed and that over 80% of genotypes can be easily regenerated from the mature cotyledon explants.

Specific Cytogenetic Characteristics of Pinus cretaceae and Pinus sylvestris

Russian Journal of Ecology, 2004
A comparative cytogenetic study has been performed in four populations of two pine species, Pinus cretaceae Kalen. and P. sylvestris L., growing on sandy and chalky substrates in Voronezh and Belgorod oblasts. Significant differences in the parameters of mitotic and nucleolar activities, as well as the rate and spectrum of mitotic pathology, between ...
