“…The results of this study showed that regardless of nitrogen fertilizer treatments, a decrease in SMC significantly limited all investigated growth characteristics of P. orientalis seedlings, which was in agreement with the findings of studies on some other tree species such as S. davidii (Wu et al 2008), Pseudotsuga menziesii (Khan et al 1996) and four Mediterranean oak species, including Q. frainetto, Q. conferta, Q. pubescens and Q. ilex (Fotelli et al 2000). The reasons for the growth reduction of tree seedlings under water stress conditions have been described by some authors so far (Bréda et al 2006;Shao et al 2008;Chelli-Chaabouni 2014). Water stress modifies different physiological and biochemical processes involved in plant growth (da Silva et al 2011).…”

Given the important applications of oriental arborvitae (Platycladus orientalis /L./ Franco), we examined the interaction effects of soil moisture content (SMC) and urea fertilizer on survival, growth and some physiological characteristics of seedlings of this species. In this study, 270 uniform oriental arborvitae seedlings were transplanted in 2 kg containers filled with the top soil of the natural stand in Soorkesh forest reserve. After 2 months, 6 levels of SMC (100%, 75%, 50%, 25%, 15% and 10%) and 3 levels of urea [control: 0, low nitrogen (LN): 75 mg·kg–1, and high nitrogen (HN): 150 mg·kg–1] were used from June till the end of the first growing season in 3 replications and 5 seedlings per replication as subsamples. The results showed that all seedlings survived under SMC above 25% in control and urea fertilizer treatments. However, under 15% and 10% SMC, the seedling survival decreased significantly in control treatment, but adding urea fertilizer significantly increased the survival, especially in HN treatment. Growth and morphological properties of seedlings, including root and shoot length, number of first-order lateral roots and total biomass, showed a significant decrease at 75%. Seedling quality index gradually decreased with SMC reduction, but the addition of urea to the soil significantly increased it under all SMC treatments. The results also indicated that a decrease in SMC significantly decreased relative water content of leaves and total chlorophyll content, and urea fertilizer increased total chlorophyll under all SMC treatments, but it increased relative water content only at 100% to 25%. Moreover, water use efficiency of P. orientalis seedlings significantly increased under low soil moisture treatments, and urea significantly increased it, especially under HN treatment. In conclusion, urea fertilizer, especially in the higher amount (150 mg·kg–1), improved growth and quality of seedlings under different soil moisture conditions, and increased their survival under severe drought.

“…Механизмы, принятые против одного фактора стресса, не обязательно аналогичны механизмам противодействия множественным стрессам. Реакция растения может отличаться, когда два или более стресса возникают последовательно или одновременно [64]. Биотические и абиотические стрессы влияют на рост, развитие и продуктивность растений.…”

The present publication is the fourth in the series of four reviews of reports that have been published over the last 20 years to address the responses of arboreal plants at different hierarchical levels of their organization to anthropogenic factors. In the fourth part, modern methodological approaches to assessing the conditions of forests are considered and the most promising of them are distinguished. The conditions of forests under anthropogenic pollution deteriorate in general; however, the degree of deterioration much depends on tree species and pollution type. The resistance of biosystems to anthropogenic factors is based on adaptive responses involving all levels of biological organization, from cytogenetic to ecosystemic. Special attention is paid to adaptive responses related to plant resistance to metals. The development of the theory of the adaptive strategies of plants is traced starting from the Ramensky-Grime concept of phytocenotypes. The industrial pollution is a novel, in the historical perspective, environmental factor for plant. This makes it reasonable to develop further the concepts related to adaptive strategies of plant species with account for their adaptive potential, variability, resistance, and ecological plasticity. An original approach to the discovery and characterization of strategies of adaptation of plants to anthropogenic factors is proposed based on the analysis of current literature and decades of original studies.

“…When they undergo changed climatic conditions, plants develop adaptation strategies. Often, the modification of optimal conditions induces a series of changes affecting morphology, metabolism, growth, nutrition, and anatomy leading to plant stress (Chelli-Chaabouni, 2014).…”

BackgroundFlora growth is always influenced by the environmental conditions that surround the plant.The Objective of the StudyThe present research work was undertaken to study the response of Withania frutescens (L.) Pauquy to changes in the environmental conditions by investigating topographical, climatological, morphological, histological, and phytochemical aspects influencing the plant’s growth.Materials and MethodsThe topography of the study area was described using the Digital Terrain Model (DTM). The bioclimatic study was carried out using a climatological database (TerraClimate) used for an old period 1960–1970 (OP) and a new period 2000–2019 (NP). The histological study on stems, leaves, and roots was investigated according to protocols as described in the present study. The phytochemical analysis was assessed using a gas chromatograph coupled to a mass spectrophotometer after silylation.ResultsThe topographical study showed that the selected stations varied in terms of topographical characteristics. The average annual precipitation recorded for the study area was 624 mm/year, and the thermal amplitude was around 34.64°C. The morphometrical study revealed that the plant had changes in length and width from one zone to another. The histometrical study of organs showed changes in tissue structure over time and location. The phytochemical content in the studied plants was also found to vary over time and location.ConclusionBased on the obtained results, we could confirm that W. frutescens has developed alternate strategies to mitigate increasingly harsh environmental conditions.
