“…Mzabri et al [39] reported that increasing the concentration of Nacl and Kcl reduces the length of the roots in the form of saffron. Feizi et al [37] concluded that with increasing salinity stress, the number of leaves, dry weight of corm from saffron, and shoots are significantly reduced, which confirms the present results.…”

“…Plants produce reactive oxygen species (hydrogen oxide and hydroxyl) when exposed to stress conditions, including salinity stress, which degrade chlorophyll and membrane lipid peroxide. These compounds can damage plant enzymes and membranes and increase electrolyte leakage, and are therefore considered a biological indicator for estimating plant membrane damage under salinity stress [37]. Dastranj and Sepaskhah [38] reported that salinity reduces growth and increases the amount of sodium ions in all vegetative and reproductive organs of saffron, which leads to reduced growth of saffron.…”

Recent continuous droughts and decreasing ground water tables have prompted efforts to improve irrigation schedules and introduce crops that need less water. A study was recently conducted to determine suitable zones for saffron in Miyaneh using Landsat-8 images and the weighted linear combination (WLC) method. Climatic and geographical indices for saffron cultivation in the region were for soil type, slope, soil moisture, and soil salinity. Parameters such as 30 years of data on climate, soil, and water conditions were collected from synoptic and climatologic stations such as Tabriz. Then, parameters were weighted using WLC for importance in each region. The data were transferred to expert choice and clustered, rated, and integrated to produce the last layer. The results showed that the southeastern and northwestern regions of Miyaneh, especially the banks of rivers and catchments, were identified as suitable places for saffron cultivation and that 28% of the area is in the suitable class, 36% in the relatively moderately suitable class, 20% in the critical suitability class, and the rest of the area, which covers about 16% of the area, is in the non-suitable class. Therefore, if it is possible to identify favorable areas for saffron cultivation according to the climatic requirements and it is possible in practice to achieve higher performance per unit area, that in itself will contribute to improved economic conditions and levels of income for farmers. Due to the special characteristics of saffron, substituting it for the cultivation of crops with high water requirements, such as onions, potatoes, tomatoes, etc., will help reduce water consumption.

“…For instance, addition of SA to soil alleviated salt toxicity in maize by decreasing Na + accumulation [ 81 ]. Exogenous foliar application of 1.5 mM SA reduced osmotic stress and improved the aerial K + /Na + ratio of saffron under saline conditions [ 82 ]. Soaking seeds of Leymus chinensis in SA solution lowered osmotic damage on the plasma membrane by accumulating K + and Ca 2+ [ 83 ].…”

In recent decades, many new and exciting findings have paved the way to the better understanding of plant responses in various environmental changes. Some major areas are focused on role of phytohormone during abiotic stresses. Salicylic acid (SA) is one such plant hormone that has been implicated in processes not limited to plant growth, development, and responses to environmental stress. This review summarizes the various roles and functions of SA in mitigating abiotic stresses to plants, including heating, chilling, salinity, metal toxicity, drought, ultraviolet radiation, etc. Consistent with its critical roles in plant abiotic tolerance, this review identifies the gaps in the literature with regard to the complex signalling network between SA and reactive oxygen species, ABA, Ca2+, and nitric oxide. Furthermore, the molecular mechanisms underlying signalling networks that control development and stress responses in plants and underscore prospects for future research on SA concerning abiotic-stressed plants are also discussed.

“…While osmotic stress is dealt with osmotic tolerance, on the other hand, ionic stress is dealt with Na + exclusion and tissue tolerance [4,5]. Although it is believed that saffron is a salt-sensitive crop [6], there is some evidence that this plant is suitable for growth in lightly or moderately saline soil, whereas carbonate deficiency can be a limiting growth factor [7][8][9][10]. Sepaskhah and Kamgar [11] proved that the vegetative growth of saffron is not sensitive to water salinity and found a low vegetative growth reduction even at a salinity value of 4 dS m −1 .…”

The Role of Nitrogen in Inducing Salt Stress Tolerance in Crocus sativus L.: Assessment Based on Plant Growth and Ions Distribution in Leaves

The role of nitrogen (N) in inducing salt stress tolerance in plants is not well understood, and the question is more complicated in saffron (Crocus sativus L.), which is sensitive to both nitrogen rates and salinity. The present study was conducted to investigate the effects of different N (0, 50 and 150 kg ha−1) supplies on saffron growth and ions concentration in shoots under several salt stress levels (0, 3, 6 and 9 dS m−1). Salinity negatively affected plant growth assessed by leaves number, leaves length, shoot dry weight, corms number and corms weight. Moreover, there was a clear direct correlation between higher salinity value and less plant growth. Different effects due to salinity and nitrogen were evident in terms of the number and length of leaves during the growing season from day 60 after first irrigation (DAF) and achieved a peak after 90 DAF. Salt stress also affected the ions balance, as Na+, Cl− and Ca2+ were enhanced and K+ was reduced, thereby damaging the plants. Nitrogen partially mitigated the negative impacts of salinity on plant growth and ions balance, although this compensatory effect was observed when nitrogen supply was set at 50 kg N ha−1. For example, in 2019–2020, the losses in shoot dry weight due to 9 dS m−1 salinity amounted to 47%, 44% and 54%, at 0, 50 and 100 kg N ha−1 respectively, thus indicating a less negative effect of salinity at 50 kg N ha−1. Moreover, at 100 kg N ha−1 the negative effect of salinity was stronger for six and nine dS m−1. Our findings suggested that the optimum N supply (50 kg N ha−1) strengthened the plant under non-saline and moderately saline (6 dS m−1) conditions, and consequently improved salt tolerance.
