Range of soil and climate characteristics appropriate for Pistacia atlantica forest development and rehabilitation (case study: Fars province, Iran)

Abstract

Investigation of ranges of soil and climate characteristics appropriate for the tolerant species: Pistacia atlantica subsp. mutica according to field study was the main objective of this research. This study was carried out based on random sampling across 20×20 km wild pistachio forests of Fars province (Iran). Results showed that mountainous and hilly lands are the main land types that pistachio species have evolved on. Statistical analysis of physical and chemical soil characteristics based on principal component analysis (PCA) method showed that wide ranges in soil characteristics, even up to about 40% differentiation in some measured properties, did not restricts this subspecies natural growth. The main growth limiting factors were shallow soil depth and light soil texture that decreased storage capacity of soil moisture, necessary for wild pistachios survival during drought and long dry periods. Climatic elements were analysed through the same approach and showed that temperature, precipitation and wind with overall variability of 85.9% were the most effectual factors. Pistacia atlantica subsp. mutica is one of the species refractory to various soil conditions and adapted to weak soils for the establishment and rehabilitation of forests in semi-arid regions.

Adsorption Isotherm and Kinetics Study: Removal of Phenol Using Adsorption onto Modified Pistacia mutica shells

“…The fruit of p. mutica is also an important source of food, although the fruits are smaller and not as commercially valuable as those produced in orchards (primarily from cultivars of Pistacia Vera L). Old trees may have trunks measuring 2 m (6 ft 7 in) in diameter; it may take 200 years for a tree to reach 1 m wide (17,18). The main purpose of this study was to investigate the P.mutica shells efficiency in the removal of phenol from aqueous solution.…”

EVALUATING THE COMPETITIVE ENVIRONMENT FOR WILD PISTACHIO (Pistacia atlantica Desf.) SEEDLINGS IN THE CENTRAL FORESTS OF IRAN

“…Seedlings are sensitive to excessive cold and longtime drought (Bagheri et al,2014). In dry periods, the texture and depth of the soil become important enough to determine the survival of new plants (Nejabat et al, 2017).…”

Analysis of principal components used for modelling changes in glacitectonically disturbed areas

“…No. 39 (X-XII) been widely used in recent years for modelling such nonlinear phenomena as atmospheric studies, meteorology, biometrics, statistics, geophysics and civil engineering [NEJABAT et al 2017;TIAMPO et al 2017]. The PCA method has also been successfully used for solving geodesic problems.…”
