Pines are major components of native forests and plantations in Europe, where they have both economic significance and an important ecological role. Diseases of pines are mainly caused by fungal and oomycete pathogens, and can significantly reduce the survival, vigor, and yield of both individual trees and entire stands or plantations. Pine pitch c...

Pine pitch canker (PPC), caused by the pathogenic fungus Fusarium circinatum (Nirenberg and O' Donnell), is a serious threat to pine forests globally. The recent introduction of the pathogen 2 of 34 to Southern Europe and its spread in Mediterranean region is alarming considering the immense ecological and economic importance of pines in the region...

The fungal pathogen Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker (PPC) disease, which seriously afects conifer species in forests and nurseries worldwide. In Europe, PPC is only established in the Iberian Peninsula; however, it is presumed that its range could expand through the continent in the near futur...

Present study has the aim to promote interspecific chestnut selections that can be grown in Romania. Previous selection work into the local sweet chestnut (Castanea sativa Mill.) populations has been carried out by SCDP Vâlcea since 1992. As a result, two sweet chestnut cultivars (‘Romval’ and ‘Casval’) have been named. Most of the sweet chestnut o...
Article
Asiatic pathogen Cryphonectria parasitica produced dramatic diebacks of American chestnut (Castanea dentata) and European or sweet chestnut (Castanea sativa) throughout their natural or artificial range, both in forests and orchards. Fungus chemical treatment is a useless (curative) to a less important (preventive) tool. Biological control of Cryph...

Asiatic fungus Cryphonectria parasitica has gradually infected all chestnut habitats, forest and horticulture plantations from the most important natural centres of sweet chestnut distribution in Romania. The objectives of this work were to understand the destruction rate of chestnut habitats under C. parasitica pressure, and to test the efficacy o...

The decline phenomenon of stands can be defined as the totality of effects that damage the normal vegetation state of trees and stands. There are two types of decline, the acute one, with fast development, and the chronical one, with slow development in space and time. The accurate capture of the phenomenon has direct implications for the forest ma...

Fusarium circinatum, the causal of pine pitch canker disease (PPC), is now considered among the most important pathogens of Pinaceae in the world. Although in Europe PPC is only established in the Iberian Peninsula, the potential endangered areas cover over 10 million hectares under the current host distribution and climatic conditions. It is there...

Mushrooms have a special position in many cultures where they are used as food, medicine, handicrafts, have special cultural significance as symbols or in rituals and are a motivation for forest recreation. However, there is also a dark side to mushrooms which are also associated with poisoning, decay and death. This dichotomy is reflected in the s...

Dothistroma needle blight (DNB) caused by Dothistroma septosporum and Dothistroma pini is a damaging disease of pine in many countries. The disease led to the abandonment of planting susceptible Pinus species in parts of Africa, Asia, Australasia, Europe and North America. Although the disease can be effectively controlled using copper fungicides,...

Dothistroma needle blight (DNB) is one of the most important diseases of pine. Although its notoriety stems from Southern Hemisphere epidemics in Pinus radiata plantations, the disease has increased in prevalence and severity in areas of the Northern Hemisphere, including Europe, during the last two decades. This increase has largely been attribute...

Sweet chestnut (Castanea sativa) is a protected species in Romania, due to its rare natural occurrence (around 400 ha of forest dominated by chestnut and <2000 ha with chestnut in NW and SW of Romania) and high value. The invasive fungus Cryphonectria parasitica has destroyed all the chestnut forests and orchards in NW and the same phenomenon is pr...

Tilia spp. (lime trees) as ornamental trees have a privileged place in the European mythology and traditions and this is a reason of their constant presence in the urban landscape. Lime trees are in general very resistant to biotic and abiotic stress, although some sanitary problems may occur (e.g. aphids and other related organisms). Tilia spp. ar...

Poplar and willows are the main fast growing tree species used for biomass production in short rotation coppiced (SRC) cultures. The main characteristics for biomass production (plant survival, basal diameter and height increment) after first growing season are presented. Four Italian clones - AF2, AF6, AF8 and Monviso (Alasia New Clones) and two c...
Article
A large database of invasive forest pathogens (IFPs) was developed to investigate the patterns and determinants of invasion in Europe. Detailed taxonomic and biological information on the invasive species was combined with country-specific data on land use, climate, and the time since invasion to identify the determinants of invasiveness, and to di...

Research on mycorrhizas in Romania started some 60years ago, first in forestry, then in agriculture and finally in horticulture. The main studies have covered the following topics: (i) The mycorrhizal symbiosis; (ii) Ectomycorrhizas in natural forest ecosystems; (iii) Mycorrhizas in agriculture and forestry; (iv) Field methods, e.g., the developmen...

The determination of energetic characteristics of six types of poplar clones was achieved, four developed by Alasia New Clones -Italy, (AF-2, AF-6, AF-8, Monviso) and two by ICAS -Romania (Turcoaia, Sacrau-79); they were cultivated for different pedoclimatic conditions in Romania. The plant survival rate and biomass production rate were analyzed in...

The dieback of European beech trees has occurred in the northeast of Romania since 2000, but beech decline has also been noticed in other regions. The disease factors have been recorded in 11 experimental plots (of which 6 permanent) and along different transects. The most important decline factors seem to be the climatic conditions (drought of 19...
