Influence of Osmotic, Salt, and Combined Stress on Morphophysiological Parameters of Chenopodium quinoa Photosynthetic Organs

Chenopodium quinoa Willd. is an annual facultative halophytic pseudocereal widely studied for its physiology and grain yield owing to great tolerance unfavorable growing conditions. However, the morphophysiological anatomical characteristics of plants’ photosynthetic organs under various combined abiotic stresses during early stages development have not been thoroughly studied. Therefore, current study compared influence osmotic, salt, stress at different intensities on morphology anatomy in young plants. The main findings demonstrate that salt intensity between 100 200 mM NaCl critical growth plants can withstand 300 NaCl. it be concluded some adaptation mechanisms were already violated a NaCl, while significant changes water balance observed possibly caused by damage cell structures.
