Somatic Embryogenesis in Pinus spp.

2016
Somatic embryogenesis (SE) has been the most important development for plant tissue culture, not only for mass propagation but also for enabling the implementation of biotechnological tools that can be used to increase the productivity and wood quality of plantation forestry.

Diseases of pine (Pinus spp.)

1982
The European Pinus sylvestris (Scots pine) and P. nigra var. maritima (Corsican pine) and the North American P. contorta (lodgepole pine) are the major species of pine grown in British forests. Many other introduced pines are grown in parks and gardens. P.

Characterization of Fusarium circinatum from Pinus spp. in northern Spain

Mycological Research, 2007
Pitch canker caused by Fusarium circinatum was recently reported on Pinus spp. in Spain. In this study, a collection of 157 isolates of F. circinatum obtained from different geographical origins and hosts in northern Spain were identified and characterized by cultural and morphological features, PCR-RFLPs of the histone H3 gene, IGS region, and the ...

Revealing past needle retention in Pinus spp.

Scandinavian Journal of Forest Research, 1990
Needle retention in conifers is affected by several environmental factors, e.g. climate, mineral nutrition, other edaphic conditions, and more recently by air pollution.

Revealing past needle density in Pinus spp.

Scandinavian Journal of Forest Research, 1998
The number of short shoots per shoot length, or needle density, is species typical, and it shows year‐to‐year variation within species. By modification of the needle trace method, long‐term needle density chronology was produced in a Scots pine (Pinus sylvestris L.) stand, located at the northern timberline in Finland.

Traumatic resin ducts induced by methyl jasmonate in Pinus spp

Trees, 2020
Key message: Exogenous MJ does not alter the resin duct structure of pines in the cortex, but increases the number, density and mean size of resin ducts in the secondary xylem, particularly in Pinus sylvestris and P. radiata. Abstract: Methyl jasmonate (MJ) is an organic compound capable of modulating defence responses in plants.

Ectomycorrhizae synthesized between Pinus radiata and eight fungi associated with Pinns spp.

Mycologia, 1996
The capability of several fungal species, collected in the field in association with species of the genus Pinus, to form ectomycorrhizae with Pinus radiata have been determinated in vitro and in con- tainers. Hebeloma longicaudum, Russula sanguinea, Tricholoma albobruneum, Tuber borchii and Xerocomus badius have formed ectomycorrhizae with Pinus ra ...

Fertilizing container grown Pinus nigra spp. Laricio

1994
Les résultats décrivent les caractéristiques morphologiques des plants après une saison de végétation, leurs besoins structuraux, la fertilisation-type. Cette démarche peut s'étendre aux principaux résineux produits en région méditerranéenne française.

Arid environments select for larger seeds in pines (Pinus spp.)

Evolutionary Ecology, 2019
Seed mass is a main determinant of seedling establishment, particularly under stressful conditions, as bigger seeds offer more resources to the emerging seedling. This has led to the expectation of increased seed mass under harsh conditions. Here, we studied the role of different components of environmental harshness on the evolution of seed size in ...
