“…The optimal NaCl concentration for growth is 100 mM in L. bicolor and 50 mM in L. gmelinii, based on determination of the distribution pattern of salt glands (Leng et al 2018). Limonium sinuatum has higher salt resistance than other Limonium species (Akat et al 2020). There were no adverse effects on L. pectinatum irrigated with 200 mM NaCl for 4 months, where floral stems (number, height and dry weight) were unaffected (Morales et al 2001).…”

Limonium Mill. plants are typical recretohalophytes, as they withstand salt stress by secreting excess salt onto the leaf surface through salt glands. However, little is known on the salinity thresholds of these plants and the function of salt glands in salt tolerance.• Here, we investigated the salinity thresholds of salt tolerance of the Limonium species L. aureum (Linn.) Hill, L. gmelinii (Willd.) Kuntze, L. otolepis (Schrenk) Kuntze and L. sinuatum (L.) Mill grown with various concentrations of NaCl.• The salinity thresholds of L. otolepis, L. aureum, L. sinuatum and L. gmelinii were 300, 350, 400 and 420 mM NaCl, respectively. Correlation analysis indicated that total dry weight, chlorophyll content and intercellular CO 2 concentration were highly positively correlated with the total fresh weights of all four Limonium species and could therefore be used as indicators of plant salt tolerance. Furthermore, as the salt gland density on the leaf surface increased, the rate of salt secretion per salt gland also increased, allowing more Na + to be secreted from the plant. Redundancy discriminant analysis indicated that salt gland density, Na + content and Na + secretion rate per salt gland were positively correlated with salt concentration.• These observations support the notion that salt glands play important roles in the adaptation of Limonium species to high salinity conditions.

“…The flower petals are white, while the calyxes can be different colored (e.g., white, blue, pink, yellow, and purple) 4 . The calyxes remain long after the petals have disappeared, making the flowers attractive for long periods of time and excellent for use as fresh cut flowers or in dried arrangements 5 . The flower stems are approximately 40–50 cm tall, each flower stem has 2–3 branches with 5–6 flowers clustered together, and the diameter of each flower is ~ 0.5 cm 6 .…”

Limonium sinuatum, a member of Plumbaginaceae commonly known as sea lavender, is widely used as dried flower. Five L. sinuatum varieties with different flower colors (White, Blue, Pink, Yellow, and Purple) are found in saline regions and are widely cultivated in gardens. In the current study, we evaluated the salt tolerance of these varieties under 250 mmol/L NaCl (salt-tolerance threshold) treatment to identify the optimal variety suitable for planting in saline lands. After the measurement of the fresh weight (FW), dry weight (DW), contents of Na+, K+, Ca2+, Cl−, malondialdehyde (MDA), proline, soluble sugars, hydrogen peroxide (H2O2), relative water content, chlorophyll contents, net photosynthetic rate, and osmotic potential of whole plants, the salt-tolerance ability from strongest to weakest is identified as Pink, Yellow, Purple, White, and Blue. Photosynthetic rate was the most reliable and positive indicator of salt tolerance. The density of salt glands showed the greatest increase in Pink under NaCl treatment, indicating that Pink adapts to high-salt levels by enhancing salt gland formation. These results provide a theoretical basis for the large-scale planting of L. sinuatum in saline soils in the future.

“…Yasemin (2020) [20] also presented that branch number and length of Zinnia elegans and Zinnia marylandica decreased as salinity increased. There are several studies that shown reducing plant heights and biomass under saline conditions [16,14,17,21,22,6,23]. There is not too much known the effects of salinity on flowering parameters.…”

Chrysanthemum which belongs to Asteraceae is one of the most important ornamental plants in the world. Chrysanthemum morifolium Ramat 'Bacardi', a species of this genus, is a very important cut flower used as spray chrysanthemum. Salinity in soil and water is one of the major problems which affect the ornamental aspects and plant growth. It was aimed to determine the effects of salinity on Chrysanthemum morifolium Ramat 'Bacardi' by analyzing plant growth, flower characters and some physiological traits in this study. Plants were irrigated with seven different levels of salt concentrations (0, 50, 100, 150, 200, 250 and 300 mM NaCl) for 75 days with 3 days intervals in pots under greenhouse conditions. The effects of salinity stress on diameter of flower and disc floret, number of bud and flowers, fresh and dry weights of flower, shoot height, shoot fresh and dry weights, stem diameter, lateral shoot (branch) length and number, inter-node length, relative growth rates, loss of turgidity and ion leakage were investigated in this study. Consequently, flower and disc floret diameters, number of flowers, shoot height, shoot and flower fresh and dry weights, stem diameter, branch length and number, inter-node length were drastically decreased, as the salinity increased, especially after 200 mM. On the other hand, ion leakage significantly increased when salt concentrations increased. According to the results, C. morifolium Ramat 'Bacardi' is moderately tolerant cultivar and should not be cultivated as a cut flower up to 150 mM NaCl (highly saline) conditions.
