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 ...

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.

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 ...

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.

DEAD-TOP OFPINUSSPP. IN VICTORIAN PLANTATIONS

Australian Forestry, 1957
SUMMARY Field surveys of several Forests Commission pine plantations revealed the presence of dead-top in some areas. The evidence suggested that the disorder was. associated with moisture stress during hot, dry summer months in Pinus spp. growing on shallow soils with a high tree density. Affected sites usually had exposed northern or westerly aspects.

Needle cast disease on Pinus spp. by Lophodermium seditiosum.(Arrossamento degli aghi di Pinus spp. da Lophodermium seditiosum).

1993
Almeno quattro sono le specie di Lophodermium identificate e descritte sugli aghi di Pinus spp., un tempo raggruppate tutte sotto l'unica denominazione di L. pinastri (Schrad. ex Hook) Chev. (Jones, 1935) ed oggi riconosciute come specie distinte, in base a vari caratteri tra i quali il diverso grado di patogenicità. Mentre L. pinastri, L.

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.
