43. Effect of various salinity levels on growth and development of Chenopodium album plant
Abstract
The present study shows the ionic and osmotic relation in Chenopodium album by the keeping the plant in different salinity levels i-e in six salinity levels (0-250mm NaCl range) for 60 days. The stress of salt was provided earlier to the soil, before the seed were potted by the help of water which were used for irrigation. The growth and development of plants were occurred between 110 mm to 150 mm NaCl. The plants possess a very strong and precise system to become stable osmotically against sudden and abrupt increase in NaCl stress. It was investigated that up to 88% of osmotic stability was in mature leaves which were achieved due to accumulation of inorganic ions (Na+, K+, and Cl-). At the provide NaCl concentration. The compound which affects the osmosis was also very low. By providing all the salinity treatments from (0-250mm) the mature leaves have more concentration of Na+ and low concentration of K+, while the higher K+ and low Na+ were found in young leaves. Another application of shoot sap consists of K+ progressively increases with increase the concentration of the salt in mature leaves. A very efficient relation between NaCl change H+ and K+ concentration were observed in the root of such particular plants. This report clear the work and character of inorganic ion for osmotic stability in salt loving plant, and also make the mechanism clear of Na+ in vacuole, and also their uptake movement in shoots.
