SEEDLING GROWTH OF WHEAT AND RICE CULTIVARS IN RELATION TO SALINITY | BIONATURE

In petridishes, researchers investigated the influence of salinity on seedling response and shoot water content in wheat (Inia 66 and Somalika) and rice cultivars (Biplab and Chandina). Distilled water (control), 1000, 4000, and 8000 ppm NaCl were used as salinity treatments. At the maximum salt level, the water content of rice shoots and, to a lesser extent, wheat showed a reduction, but showed a positive reaction at 1000 ppm NaCl. At the lowest salinity level, both root and shoot were similarly impacted, but from 4000 ppm onwards, the dry weight drop was greater in the shoot than the root. At the highest salinity treatment, both wheat and rice cultivars showed a considerable loss in shoot and root length. At 1000 ppm NaCl salinity, the development of both wheat and rice seedlings was accelerated.
