Incorrect use of agricultural techniques is determining the apparition of saline soils. From the world total arable land surface, 8% is affected by salinity (1). Excessive amounts of salt may induce alterations of plant functions and structures (2). Assessments must be performed to find species suited for affected soils (3). The main aim of the present study is the determination of salinity influence on processes involved in development of basil plants and the suitability of cultivating this species, an important crop of culinary and medicinal interest, on saline terrain. Materials and Methods: Basil seeds were bought from a specialised store and peat based substrate was used for germination. During the testing the plants were potted using a universal soil mixture NaCl was applied in 3 concentrations (4mM, 10mM and 20mM). For plants anatomy, sections were made using a hand microtome and dyed using Iodine-green and Ruthenium-red. Chlorophyll and carotenoid pigments were evaluated as in (4). Total phenolic content was determined using methods described in (5). Results: Anatomical analysis indicated that on higher NaCl concentration the number of xylem vessels increased, to compensate dehydration, similarly to (4). Chlorophyll fluorescence decreased, with variations during 2 weeks of treatment. Salinity determined a reduction of photosynthesis efficiency, influencing chlorophyll production. Salt presence lead to increased flavonoid and total phenolic contents and reduced chlorophyll contents. Similar results were observed by (4) and (5).Conclusion: Considering that basil plant grew under salinity stress, basil crops appear suited for cultivation in salinity affected fields, with positive effects on the economic value of the crop. |
