The Effect Of Salt Concentration On Plant Growth - 1193 Words

Research question Does salt concentration effect plant growth? Aim To investigate the effect of salt concentration in soil on plant growth Hypothesis As concentration of salt increases, the growth of plant will be detrimentally effected when grown in a controlled environment. Background theory Plants are a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, absorbing water and inorganics substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll (Oxford Dictionaries, 2015). Plants are the backbone of all life on Earth and an essential resource for human well-being (BGCI, 2015). For all forms of life, plants form the basic food staples. They are the major source of oxygen and food on earth since no animal is able to supply the components necessary without plants (Jennifer C, 2014). Plants make food – they are the only organisms that can convert light energy from the sun into food. Plants make oxygen – one of the materials that plants produce as they make food is oxygen gas for animals and people to stay alive. Plants provide habitats for animals – it is a primary habitat for thousands of other organisms. Plants help make and preserve soil – the roots of plants help hold soil together which help reduce erosion and helps conserve the soil. Plants provide useful products for people – many plants are important sources of product that people use, including food, fibresShow MoreRelatedThe Effect of Salt Concentration on Grass Growth1414 Words   |  6 PagesThe effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water, watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt, the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growthRead MoreEnvironmental Factors That Affect Plant Growth Essay1145 Words   |  5 PagesIntroduction All the factors that inhibit plant growth are defined as stresses. Environmental factors influence the characters, composition, growth and development of individual plants and plant communities. When any of these environmental factors exceeds the optimum tolerance of a plant, it produces stress to the plant influenced by the developmental, structural, physiological and biochemical processes of the plant. Towards a stress definition Levitt 1980 defined stress as any environmentalRead MoreThe Use Of Magnetite Nanoparticles And Its Effects On The Environment931 Words   |  4 Pagesleaves decreased in different concentrations of NaCl (Table 1). Several factors such as reduction of photosynthesis, degradation of cell membranes, reducing of plant available water and Na+ accumulation in the leaves were the main causes of weight loss under salt stress (Hajiaghaei-Kamrani et al., 2013). Also results showed that Fe2O3NPs treatments increased the FW and DW values as compared to the control plants. The highest value of leaf FW and DW at all concentrations of NaCl were observed in 30Read MoreCoal Seam Gas853 Words   |  3 PagesQueensland depends at times on underground water. The effect of CSG extraction using underground fracturing on underground water is not clear. Basic sets of impacts that are broadly well understood are that aquifer levels will sink dramatically and will depressurise. It also risks groundwater con tamination and the salt that is present in the water of coal seams will be brought to the surface as well, in a quantity of about 1.8 million tonnes of salt per year (ABC, 2010). There are several types of waterRead MoreThe Effect Of Salinity On Growth And Development1508 Words   |  7 Pagesgravitropism: The effect of salinity on gravitropism shown in downward root growth Background information: Gravity greatly influences plant growth and development. When plants enters the first stages of growth, the primary factor that determines the outcome of the plant’s survival is gravitropism. Gravitropism, determines upward shoot growth to secure a correct positioning of the leaves for efficient photosynthesis and gas exchange. Gravitropism primarily determines the downward growth of roots. GravityRead MoreSalt Pollution1495 Words   |  6 PagesSalt Pollution As awareness for pollution increases, other forms of pollution are defined. Almost everyone knows about toxic waste and carbon dioxide pollution, but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe, an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environmentalRead MoreSalinity And Its Effects On The World s Most Serious Environmental Problems1100 Words   |  5 Pagespopulation, especially in arid and semi-arid regions, food shortages, and land scarcity are compelling the use of lands not utilized because of salinity and other soil stresses. Salinity and sodicity problems are characterized by an excess of inorganic salts and are common in the arid and semi-arid lands (ASAL) where they have been naturally formed under the prevailing climatic conditions and due to the high rates of evapotranspiration and lack of leaching water (Mengel and Kirkby, 1982; Shannon et alRead MoreThe Effect Of Stress Levels In Plants859 Words   |  4 Pagesthat salinity stress levels increased sodium and decreased potassium contents in the shoots and fruits of pepper plants which is a typical response of plants in saline environments arising from the inability of plants to distinguish between sodium and potassium ions (Storey et al., 1983). The increase in Na+ content mainly in the vacuole provides an osmotic adjustment of salt affected plants (Sakr et al., 2007). This accumulation might be due to the important role of sodium in increasing osmotic pressureRead MoreThe Pollution Of The United States1558 Words   |  7 Pagessnowfall, it is a common practice to pour salt on the roads. The reason for this is because a property of salt allows it to lower the melting point of water, which makes it much easier to clear the streets of snow and ice that would otherwise leave the roads dangerous, unusable and slippery. It is a simple way to reduce car accidents, and it is also much cheaper compared to the alternative chemicals that can be used for the same purpose. However, the salt that most cities use doesn’t simply disappearRead MoreThe Causes of Waterlogging from Irrigation Essay831 Words   |  4 Pagesto increase production of arable farmland to maintain the ability to feed the ever increasing population. Irrigation is generally considered the most effective way of increasing farmland production. It can help supplement the water needed for crop growth when rainfall is at a low point or, in more humid areas, it can help bridge dryer times and reduce agricultural risks. The goal of irrigating is to increase the land usable for crops, the crop production per harvest per season, and the diversity of
