“…Cold stratification temperature used in this experiment (4°C) provides an adequate moist chilling treatment. The temperature is also within the range of soil temperatures likely to be encountered in the field in high altitude Iran (Tabari and Talaee 2011;Ghasemi, 2015;Aghajanlou and Ghorbani 2016;Shirvani et al 2018). This cold stratification temperature has been reported as successful in breaking dormancy in studies of alpine and high altitude species (Baskin and Baskin 2014).…”

Ferula assa-foetida and F. gummosa, Apiaceae, are important endemic and endangered medicinal plants. Survival of the species is threatened by climate change, overexploiting (as source of oleo-gum resin and for-age) and lack of organized cultivation. Cultivation of these valuable medicinal plants is restricted by insuffi-cient domestication knowledge. Germination characteristics of different populations of Ferula taxa were studied with the aim of describing and comparing their responses to continuous cold stratification condition. Germination cues for the species were complex, with dormancy mechanisms present to restrict germination until cold stratification are fulfilled. Results indicated that a period of 4 weeks of stratification is sufficient for germination of F. assa-foetida, but optimal germination of F. gummosa require stratification for periods of 8 weeks. Both species were able to germinate at very low temperatures (4°C). Within-taxon differences in dor-mancy breaking and seedling emergence may interpret as local adaptations. The continued regeneration and propagation of the species in the wild will depend on the temperature and moisture status of the soil during winter and the maintenance of conditions suitable for stratification for an appropriate length of time.

“…However, the study of PLB is still unexplored considering observational data scarcity. Some studies also found the warming trend was higher in soil temperature than in air (Knight et al 2018;Shirvani et al 2018). Where there is a lack of in situ data, some scholars used the ensemble of regional climate models and reanalysis data to analyze soil temperature trend in different regions and also found significant LST and ST warming in Swedish boreal forests (Jungqvist et al 2014) and Tibetan Plateau China (Yang et al 2020).…”

“…Knight et al (2018) analyzed trends in soil temperature and atmospheric variables from 1942 to 2010 in Australia, a signi cant increasing trend in the context of global warming was reported in ST magnitude (Knight et al, 2018). Shirvani et al (2018) assessed trends in soil and air temperature magnitudes over Iran during 1987-2016. The study inferred a warming trend in both air and soil temperature; however, the increase in magnitude was higher in soil (Tian et al, 2011).…”

A regional analysis of soil temperature (ST) is essential for improving our understanding of the soil thermal regime and its link with the atmosphere. This study attempts to assess trends in the Poyang Lake Basin (PLB) ST magnitude during 1960–2016 from station observations at multiple depths. The Mann-Kendall, Thiel-Sen, linear regression and probability density statistics (PDF) are used for ST trend assessment with a significance level of 95%. The ST seasonal variability shows minimum values in winter (8℃) and maximum in the summer season (32 ℃). On an interannual scale, spring and winter seasons exhibited a significant increase in both land surface temperature (LST) (0.4℃, 0.4℃) and ST (0.3ºC, 0.15℃) magnitude than summer (LST − 0.1℃, ST 0.2℃) and autumn seasons (LST 0.3℃, ST 0.2℃). The northern basin exhibited a significant increase in LST, and ST magnitude, especially during the cold seasons (spring, winter) than the warm seasons. The maximum and minimum temperature trend and their diurnal difference infer an increase in the minimum temperature, especially during the summer, autumn, and winter seasons. The PDF further inferred that extreme cold events' frequency decreased, and a significant increase in extreme warm events is obvious in the recent decade. The increasing trend in soil temperature magnitude is more in the northern basin than the high-altitude southern basin. Large-scale global warming and regional water and energy cycle changes can be the leading factors of such a warming trend.
