The aim of this study was the analysis of the radial growth performances and the resilience to drought of 8 halfsib provenances of Norway spruce with narrow crown (pendula form) and normal crown (pyramidalis variety) from Soveja comparative trial, at the age of 23 years, by measuring and...

The objective of the present research consisted in the comparative analysis of the growth performances and the survival rate for the hybrids obtained by controlled pollination, in a complete dialel and factorial dialel mating design, of Norway spruce trees with narrow crown (pendula form) and...

The growth and survival of forests within the Republic of Moldova boundaries depend on the variability of the thermal and pluviometric regime of the last decades, ultimately being expressed by increasing of temperature, the losses of water required for evapotranspiration and climate aridization....

The meteorological whims, pollution, and the inadequate care of wood species from green spaces from urban and rural environment lead to take some necessary suitable decisions of tree management: (i) monitoring the health state; (ii) the control of disruptive factors; (iii) the prevention of wind,...

The abundance of scientific evidence has shown that many synthetic drugs can cause serious adverse effects in patients. Lately, the search for natural therapeutic agents with low adverse effects has attracted much attention. Considerable interest has been focused on edible and medicinal plants,...

The approaches are suggested to evaluate the injuriousness of pests of regeneration (in Scots pine plantations up to 5-7 years old), the threat of foliage damage in closed forest stands, and the harm from xylophagous insects. The first approach gives the possibility to evaluate the effect of the...

Forest crops in solariums, nurseries, plantations, etc. are frequently affected by numerous harmful factors and preventing or limiting the damage caused by these factors requires a correct and rapid diagnosis of them. However, the correct diagnosis is a complicated process and in our specialized...

The paper presents the results of a study on growth particularities of the sea buckthorn (Hippophae rhamnoides L.) varieties 'Cora', 'Clara', 'Mara' and 'Dora' depending on the tree training system: (1) bush; 2. tree with the trunk height of 45-50 cm, with annually pruning of fruit branches; 3....

Located almost at the upper altitudinal limit of forests, on rocky slopes, the spontaneous Carpathian larch has a disjunctive natural range in Romania, represented by small, relict populations. Concerning the water loss dynamics it holds obviously the supremacy in comparison with the associated...

Romanian forest seedling production system is still very classical. A complex structure of treatments for the culture and protection of forest seedlings, including stimulants (of rooting and metabolism), fertilizers, fungicides, and insecticides. Solar (plastic tent) tests were made on very young...
