Studying the Physiological Resistance of Tamarix in the Desert

The salt-loving plant Tamarix is a valuable shrub that is cultivated for various purposes, including preventing soil erosion. Seed germination and seedling growth are critical and vital stages of this plant's growth. For this purpose, seed germination and seedling growth at different levels of osmotic potential (caused by the use of sodium chloride) and temperature were carried out in a randomized complete block design around the greenhouse of Semnan University. The secret of the tooth-like model The results of this study showed that the highest tolerance of this plant's seeds to extreme salinity concentrations was observed during germination at a temperature of 15 ° C. So that at a temperature of 25 ° C, the germination percentage at extreme salinity concentrations of -2.8 and -3.2 MPa was 22 and 68 percent, respectively. The seeds of this plant are capable of germination in a wide temperature range (from 1 to 45 °C). These findings can be useful in interpreting the ecological and physiological responses of Tamarix seed germination, in improving the tolerance of seed germination to salinity stress under desert and water deficit conditions, and in increasing the chances of successful establishment in desert ecosystems with water stress. The root system in Tamarix The drier the environment, the greater the tendency for increased root development and reduced crown development. In annual plants, dry root zones may comprise 30-40% of the total dry matter of the plant, while this proportion may reach 90% in perennial desert species of Tamarix.
