Abstract
Winter Rye (Secale cereale L.) is an important food stock that are found on most part of the world that are coastal areas, which are now open to threats as global warming causes multiple issues that includes soil salination and high-concentration nitrogen run-off. As of right now, it’s already clear that salt will place a growth stress on most plants in high concentrations and will prohibit critical organs for nutrient intake, yet a number of researches stated that high dose of nitrogen will restore the growth of most wild and commercial plants. We are interested to find out how the interaction between salt and nitrogen can interfere with the growth of winter rye. A standard comprehensive 2-variable greenhouse assay was set up, with different levels of salt and nitrogen. After a 3-week growth period, an ANOVA test was conducted. The plants performance was inhibited when they are exposed to the lowest salt concentration and medium to high levels of nitrogen. In high saline environments, however, the performance of the plant was improved as it’s exposed to medium and particularly, high nitrogen levels. The finding of this study would be useful in ways that few previous studies had focused on the effect of salt and nitrogen stress on the grown of food species in case of global warming and population growth, and the subject should be studied on more food species in future researches.
Highlights
Native to Central and Eastern Europe, Winter Rye (Secale cereale L.) is a major food stock for baking and livestock feeding, and as a renewable energy source [1]
From the raw data captured in this study, two histograms with error bars were constructed, both displaying the combined effect of salt and nitrogen on the growth of winter rye after 3 weeks of growth period
The histogram on the left was grouped by the same salt concentration, while the histogram on the right was grouped by the same nitrogen levels
Summary
Native to Central and Eastern Europe, Winter Rye (Secale cereale L.) is a major food stock for baking and livestock feeding, and as a renewable energy source [1]. In the past 10 to 20 years, climate change had always been at the concern of those studying food scientists as well as ecologist given its potential for causing sea level rise and coastal soil salination. Soil salinity largely affects plant growth in various regions of the world, limiting 20% of the cultivated areas as well as 50% of the irrigated areas worldwide [4, 5, 6]. The challenge became worse as new research with their data suggests the significant existence of over-the-land transport of nitrogen-rich dissolved urea fertilizer towards sensitive coastal areas and its waters [7] , concentrating and presenting challenges towards the plants that grow in such areas, which may result in costal region’s further salination [8]
