Task 3 Experiment - Coursework Example Resistance to the salinity levels by seeds is important to ensure plant survival. Soil sanitization degrades the soil. Building up of minerals (Sodium, Potassium, Magnesium, Calcium, etc.) in these lands is due to evaporation. The condition is further worsened by over irrigation and excessive evaporation. Though some plants are tolerant to high salinity levels, others have little or no salinity tolerance. A high salt content interferes with the germination of seeds as it prevents roots from osmotic activities. This regulates the amount of nutrients and minerals being taken up by the plant. The Osmotic activities has been said to be partially if not fully, involved in the salt tolerance of certain plants (Neto et al., 2004). According to Bajji, he argues that the ability of the seed bank to remain dormant in high salt levels and germinate immediately after reduction is very significant in plants adapting and colonizing their environment as it ensures life continuity. (Bajji et al., 20 02) Measuring salt into cup on scales. In case the needed weight is less than the scale’s smallest increment, measure about 2 or 4 times that amount, and halve it using a spatula. Put the measured amount in a graduated cylinder. Carefully add the measured salt from the graduated cylinder to a measured volume of distilled water in another graduated cylinder and stir effectively. The main reason is to ensure that the salt is dissolved and evenly distributed throughout the solution. The seedlings including the control test are all stored under similar environmental conditions (Light, temperature and humidity). By varying the concentration of NaCl, one is able to compare the results by seeing how the seedlings are faring. Given that maize is widely grown in different regions with varying saline conditions, it is important we do this in order to understand that plants offer resistance to conditions that are not conducive for their
