Studying the effect of salinity on some physiological parameters of three-carbon and four-carbon plants

Abstract

The effect of salinity stress was studied in some physiological standards of two plants returning to two different light tracks (C3 pathway, and C4), two types of plants were adopted in the first study Trigonella Foenum-graecum type circuit plant returning to the group of C3Plants tricarbonate plants. The second is Sorghum-bicolor cultivar (ezrah-5) white corn, which returns to the group of four-carbon plants. three salt concentrations (50,100,150) were applied to mmol/l, which has been studied at three repeats per transaction, with the adoption of full random sectors. The results showed that salt stress caused a decrease in the amount of chlorophyll compared to the control for both plants, expelling with increased salt, while increasing the concentration of proline, sugars and phenols compared to the control for both plants. The results showed that the Sorghum-bicolor plant was more affected than the Trigonella plant.

The results showed a negative impact of salinity on certain chemical factors of both plants with a difference in the extent to which the two plants are affected due to different factors, which opens the door to studying the impact

of salinity stress on different plants and determining the extent to which they

are affected by this stress.
