“…Differences in abiotic stress tolerance among provenances of the same species from different climatic zones have been observed (Carsjens et al, 2014;Du et al, 2016;Yildiz et al, 2014), which is contrary to our second hypothesis that phenotypic divergence would not occur among provenances of the same species under waterlogging stress. This variability may be caused by differences among habitats and the duration of provenance separation.…”

Plans for hydroponic experiments, as well as the flooding of watersheds for ecological restoration, require abundant evaluation information regarding plant species adapted to waterlogged environments. In this study, we observed the growth rate and phenotypes of 57 plant species, including nine provenances of four species grown hydroponically. The 57 species were from 22 families and 33 genera, and their waterlogging tolerance (WT) was classified into five categories according to the results of the evaluation: excellent, good, ordinary, poor, and very poor. We found that 60% of these plant species were able to survive in hydroculture for more than 10 weeks. They showed new shoot growth and had a survival rate of more than 60%. Species with excellent or good WT developed new leaves rapidly under waterlogging stress, whereas species with ordinary or poor WT exhibited old leaves dropping from the stem soon after waterlogging stress. In addition, phenotypic divergence occurred among provenances of the same species under waterlogging stress.

“…This species is the most critical forest tree species in Turkish forestry owing to its ability to grow in unfavorable environments such as calcareous, dry, and poor soil conditions [4,5]. Also, this species is widely used for various purposes such as afforestation, plantation, and recreation due to a high ecologically and economically crucial roles in arid and semiarid areas in Turkey [1,6,7].…”

With climate change, global warming has increased adverse effects on living things in our country. In these adverse effects, water scarcity is the most crucial problem due to the increase in temperature and decrease in precipitation. Forests are the most affected ecosystem among others by water scarcity in our country. This study tried to determine the 5-year-old seeds and 1-year-old seedlings (produced from the same seeds) of some Turkish red pine provenance' responses to different water stress levels. First, how the water stress levels (0, -0.2, -0.4, -0.6, -0.8 MPa) affect seed germination of these provenances was determined. Secondly, gas exchange parameters [net photosynthesis (Anet), stomatal conductance (gs), transpiration (E), and intrinsic water use efficiency (iWUE)] under different water stress were determined in the seedlings obtained from these species' seeds. As a result of the germination test, Denizli-Çameli (DC) provenance had the highest rate (48%), while Maraş-Suçatı had the lowest rate (29%) under control treatment. The highest germination rate was obtained in Burdur/Bucak provenance (5%) under -0.2 MPa osmotic potential. For gas exchange parameters, Antalya/Gündoğmuş provenance had the highest Anet, gs values while DC provenance had the lowest Anet, gs, and E values when provenance is considered as a single factor. Besides, increasing in irrigation increased Anet, gs, and E while decreased the iWUE. The lowest seedling E under water stress can be explained because this species responds to the water shortage by closing its stomata. Among the Turkish red pine origins, DC provenance showed higher drought tolerance than others.

“…Historical records and modeling of future temperature and precipitation of the Central Anatolia region in Turkey, show that there is a consistent trend of increasing minimum and maximum temperatures (Kızılelma et al 2015). Additionally, species distribution models indicate that climatically suitable areas for P. brutia trees are expected to shift in a near future to higher altitudes and toward the north and northeastern regions of Turkey (Yalçın 2012). Therefore, future climate may provide an opportunity to introduce P. brutia to these regions.…”

Intraspecific variability in cold tolerance in Pinus brutia sampled from two contrasting provenance trials

Turkish red pine (Pinus brutia Ten.), is the most important tree species for afforestation in the Mediterranean basin due to its drought tolerance and fast growth rate. Cold damage to trees caused by harsh winter conditions is common on many sites in Turkey. Adaptation to climate change has been investigated primarily through the movement of species from warmer and drier climates, such as the Mediterranean P. brutia, to higher latitudes and cooler sites in central-north Turkey. In order to better guide species and provenances movement to new (and often harsh) environments for afforestation, the limits of tolerance to cold and drought should be better known. Thus, we designed an experiment to quantify the cold hardiness of nine P. brutia provenances originating from two different provenance trials in Turkey (Ankara, cold inner site; Antalya, warm Mediterranean site). Branches sampled at the end of January were exposed to cold temperatures between − 5 and − 40 °C. Visual damage observation, relative electric leakage and chlorophyll fluorometry (CF) screening methods were used to assess variation in cold hardiness among populations. Overall, P. brutia can tolerate winter temperatures up to − 16 °C. Even though there were significant differences on cold hardiness among populations, the operational application is limited due to the reduced magnitude of those differences. Measuring CF was the fastest and most easily replicated method to estimate cold hardiness and was as reliable as REL. We recommend that P. brutia should not be planted in cold areas where minimum annual temperatures are under − 16 °C. We also conclude that even though phenotypic plasticity exists for cold hardiness among the tested populations of P. brutia, the observed differences resulted from acclimation to the conditions of the provenance trial sites rather than from adaptation through natural selection.
