Effects of salinity in seed germination of Trigonella foenum-graecum and Hordeum vulgare


Land and water are essential for agricultural production, when water supply is enough for the plants, then the quality of water, soil and environment is most important to the plants (Villagra and Cavagnaro 2005). For the purpose of this report, Salinity can be defined as the build-up of salts in the soil and water or other media, which also can affect plants germination and growth. Salt is effect to all living species, plants and animals are forced to suffer from caustic amounts of salt in the freshwater supplies. Salt significantly reduces some of salt sensitive plant growth, root and shoot growth are reduced and tip burn is increased. The reason of this is salts can produce decreased water uptake, instability in metabolism and nutrient ingestion (Villagra and Cavagnaro 2005). For example, strawberries, lettuce, and avocados are especially sensitive to salt content in their irrigation water (Branson and Gustafson 1971). Australian Bureau of Statistics (2003) states that salinity has gained prominence as a national environmental issue in recent years, and around 26,000 farmers have salinity problem and try to solve it on their properties in Australia. It can be seen clearly that society conform a serious environmental problem, which need more understanding of salinity effects on plants and solution to this issue. The aim of this experiment is to find out the effects of different concentration salinity on seed germination of Trigonella foenum-graecum and Hordeum vulgare, such as 300 millimolar and 600 millimolar salt compared none salt. The null hypothesis is that there is not difference between expected and abservied value for three treatments.

One experiment was performed to determine the effects of salinity on the establishment Pearl Barley seed germination individually. Firstly, three treatments ware prepared for seed to produce different salinity environment. For this step, 58 grams of salt were dissolved in 1 liter container to made standard salt solution. Then, it can be calculated by formula C1V1=C2V2  to find out quantities of standard salt solution and pure water to mixed, in order to get specific concentration of a solution, which is 0 millimolar, 300 millimolar and 600 millimolar. Secondly, soak the seed by fully cover 50 seeds in 3 different ...
