“…There are very little data in the literature on the effects of salinity stress on D. stramonium germination. Nevertheless, some of the available data, despite not concerning germination response per se, provides a useful reference for better understanding the results obtained in this work [ 38 , 39 , 40 ]. Abdel Rahman et al [ 39 ] tested growth and dry mass production at 2.5, 5, 7.5, 10, and 12.5 dS/m plus controls, while Niakan et al [ 40 ] performed similar tests at 2, 4, and 6 dS/m plus controls.…”

In both studies, the researchers noted a reduction in shoot length and the fresh and dry weights of the roots with increasing levels of salinity stress.…”

“…The authors also found increased amounts of alkaloids in the plants exposed to salinity stress, which could be this species’ strategy to survive salinity stress. Besides alkaloids, the accumulation of some amino acids, such as proline, could also be part of this strategy [ 38 , 39 , 40 ]. Although data are scarce in the literature, there is some information on other species of the Solonaceae family that can tolerate some extreme salinity levels.…”

Weeds can be one of the most severe threats to crop production, especially when they are widespread and highly adaptable. Part of the adaptive strategy of plants is the ability to germinate in different conditions. Germination is the first developmental phase of plant life and is fundamental for its establishment. In this work, the germination of two populations of Datura stramonium L. at two different sites in Croatia (one cropped, the other non-agricultural) was tested under a wide range of salinity stress, 4, 8, 12, and 16 dS/m, and pH stress, values 1–9, at two temperature ranges of 15–25 °C and 18–30 °C. The results show that this species can tolerate high salinity, with a high number of seeds germinating, even under the highest level of saline stress and especially at higher temperatures: 21.7% of seeds germinated at 15–25 °C and 51.2% at 18–30 °C. D. stramonium also appears to be quite acid tolerant, with a significant reduction in germination only at pH 2, and no germination only at pH 1. Germination was always higher at higher temperatures, independently of abiotic stress. Although there were some differences between the two populations in the final germination percentages, they were similar in their responses to the abiotic stresses.

“…With the continuous progress of the social development and the accelerated process of industrialization, agriculture and green land area is decreased. The study of Photosynthetic Physiology plays a very important role in the selection of germplasm resources, the rational allocation of planting environment and the increase of yield in medicinal plants (Niakan et al, 2015). According to the first two chapters, we can further understand their photosynthetic and physiological characteristics by studying and discussing four kinds of medicinal plants of Platycodon grandiflorum, Atractylodis sinensis, Carthamustinctorious and Menthahaplocalyx.…”

The objective of this research was the study of research on the photosynthetic characteristics of four kinds of medicinal plants, to provide a reliable reference for the high quality cultivation of these four plants. Methods: the four kinds of medicinal plants were as the experimental materials. The photosynthetic rate, chlorophyll content, carotenoid content and photosynthesis of four medicinal plants were determined. The effects of net photosynthetic rate on photosynthetic effective radiation were studied, and the water use efficiency and transpiration rate were calculated. Results: through the comparison of net photosynthetic rate, it can be seen that the average photosynthetic rate, chlorophyll content and carotene content of the four medicinal plants are very different in the growing season. Conclusion: Platycodon grandiflorum has a wide range of adaptability to light intensity. It can not only utilize intense light efficiently, but also has shade tolerance. It is suggested to be cultivated in an intense light environment; North Atractylodes has high light utilization rate, but poor shade tolerance, it is suitable for cultivation in direct sunlight environment; Carthamustinctorious and Menthahaplocalyxhas have strong shade tolerance, but are not resistant to intense light, and can adopt intercropping.
