“…Pinus sylvestris is sensitive to drought (Eilmann & Rigling 2012) and growth is partly driven by water availability. In this area, lower latitudes present higher hydric deficit and tree growth is lower, as observed in previous studies (Candel-Perez et al 2012, Sanchez-Salguero et al 2012, Taeger et al 2013. Hagglund & Lundmark (1977) and Sharma et al (2012) also found that latitude was a good predictor variable for Pinus sylvestris L. site index in Sweden and Norway stands.…”

The assessment of forest productivity at early stages of stand development may help to define the most appropriate silviculture treatment to be applied for each stand. Site index (dominant height at a reference age) is a useful tool for forest productivity estimation. The aim of this study was to develop a model to predict site index for Scots pine (Pinus sylvestris L.) plantations in northern Spain acidic plateau by using soil (physical, chemical and biochemical), climatic and physiographic parameters. To meet this objective, data from 35 stands classified into three different site quality classes and 63 soil, climatic and physiographic parameters were examined in order to develop a discriminant model. After selecting 12 discriminant models which were biologically consistent and presented the higher cross-validated rate of correct classification, a model including four parameters (latitude, inorganic Al, porosity and microbial biomass carbon) as predictors was chosen. The discriminant model classified 71% of cases correctly and no inferior-quality stands were misassigned to the highest quality class. Soil and physiographic parameters included in the above model are easily obtainable in the field or by simple laboratory analysis, thus our results can be easily integrated in operational forestry to determine site quality.

“…The effect of precipitation in February was very close to this level. Notwithstanding this, the findings indicating that precipitation amount from May through July resulted in higher BAI were in full agreement with the presented results by another scientist (Taeger et al 2013, Zang, 2012. Meteorological multiple regression model was developed based on the monthly meteorological parameters, significance of which were higher or close to p<0.05.…”

“…Only in exceptional cases this relationship reached the level of statistical significance (p<0.05). These obtained results also very well reflected the state of knowledge on pine growth peculiarities both in Lithuania (Augustaitis et al, 2015(Augustaitis et al, , 2018Juknys et al, 2003Juknys et al, , 2014 and Europe (Taeger et al 2013).

Changing climatic conditions, increased length of growing season, competition, genotype and pollution are the most important factors for tree productivity and health. That is why only by knowing the impact of these factors on trees we can evaluate and change sylvicultural treatments that are important for the health and productivity of forest in Lithuania. The aim of the present study was to detect the significance of the competition index vs. genotype of Scots pine trees on their reactions to changes in meteorology and air pollution. Tree health, dendrometric parameters and stem basal area increment were chosen as response variables to meet the objectives of the presented study. The investigation was carried out at Scots pine genetic stand located in Aukstaitija national park, Vaisniunai district. Data on meteorology and air pollutants were obtained from ICP Integrated Monitoring Station located there. Genetically related individual groups in the stand were established by the neutral part of the genome of short repeated DNA sequence length polymorphism markers. Trees of distinctive short repeated sequences allele frequencies were grouped by Bayesian cluster analysis methods. Four genetically similar tree groups were separated in the monitored stand based on significance of ΔK value. Seven competition indices were used to determine the competition intensity effect on the tree increment and their dendrometric parameters including crown condition. The obtained results revealed that trees which demonstrated the most intensive BAI formation, best crown condition and the most significant reaction to changes in meteorology and air pollution comprised one tree genetic group while trees with adverse characteristics the second. Notwithstanding this competition intensity had the most significant effect on BAI formation.

“…In addition, it is noted that plants irrigated with water volume equivalent to 80% of evapotranspiration already presented reduced variables. Studies have associated greater drought tolerance in trees with low growth rates (Rose et al, 2009;Taeger et al, 2013. ).…”

The objective of the present study was to evaluate the initial growth of Khaya senegalensis plants under water deficit. The work was carried out at Ipameri, Goiás on a bench in full sun following the completely randomized experimental design with six treatments and six replications. 120-day-old mahogany plants (Khaya senegalensis) grown in eight-liter pots were subjected to six treatments for 12 days (plants irrigated daily with 100, 80, 60, 40, 20 and 0% of evapotranspiration) with six replications. At 132 days after emergence, the plants were assessed for: plant height, stem diameter, number of leaves, foliar area, daily transpiration, relative water content, total chlorophylls and carotenoids, leaf, stem and root mass ratios, and total biomass. The data were submitted to F-test and, when significant, to regression test at 5% probability. High stomatal control, reduced transpiration, low leaf concentration of total chlorophylls and increased root system growth to the detriment of the shoot growth indicate that Khaya senegalensis is tolerant to moderate water deficit.
