Plants are essential elements of the earth ecosystem. Despite the importance of plants to support the life on our world, our understanding of their developmental processes is still fragmentary. In nature, plants grow next to each other forming the different societies of the plant kingdom. Nature, in turn, affects the growth of these plants by applying different environmental factors that could limit the agricultural productivity. Duration, severity and rate of imposed stress are the factors underlying the plant response to stress (Munné-Bosch and Alegre, 2004; Omezzine et al., 2014).
However, we must learn to combine the benefits of both and fix the fix the hole we dug ourselves. Despite casing groundwater depletion, monocropping, and costing too much money, GMO farming is an efficient way to produce crops on a massive scale. Organic farming may be more susceptible to diseases and pest damage, but it is cheap and healthy which allows poor farmers to grow subsistence crops. It is hard to determine which type of farming is a better way of agriculture. Nonetheless, it is not hard to see the negative effects on the world that both types of agriculture leave.
(Concentrations can be seen on Table 1. Pg 25a) Auxin is an important plant growth regulator (plant hormone), and it’s quite powerful so it can be active at very low concentrations. For this experiment we used a synthetic Auxin called 1-Naphthaleneacetic acid (NAA). Auxins tend to inhibit the outgrowth of axillary shoots, and tend to promote the formation of root meristems. Cytokinin is another important plant growth regulator, and along with Auxin both of these hormones are very important in plant development.
This is the main goal of the genetically modified crops. 4)RESISTANCE TO DISEASE: Most important modification done to the crops is the disease resistance ability. Scientists have genetically restructured the DNA to withstand diseases. This helps to keep the price low for the customers. Due to high resistance, the use of
These characteristics are helpful in the production of food, allowing farmers to use fewer chemicals and to grow fewer crops with the ideal conditions to also prevent eutrophication. Pesticides can have unintentional effects on targeted species even though pesticides protect crops against unwanted insects. GMOs could harm human health as well. Researches used a particular gene from a Brazilian nut to increase Methionine in soya beans. The insertion of this gene has caused allergic reactions when the soya beans have been eaten by people who are allergic to nuts.
Historically, terrestrial habitats used to be in rigid environments, lacking in organic matter and nutrients and were not favourable to plants with primitive root system. AM fungi were important for the successful invasion of plants onto land. Fungi, with their nutrient scavenging hyphae, were able to obtain nutrient better. Today’s terrestrial ecosystem are more favourable to plant invasion, but AM fungi remain to be involved in the ecosystem processes which are the the Carbon and Phosphorus cycles. The part of AM fungi in ecosystem is obvious, but the implication of AM fungi biodiversity on ecosystem-level measures is less arguable (Heijden & Sanders,
It provides extra nutrients for the plant’s growth and life cycle. It can also increase the soil’s capability to retain water. Organic farms use humus since it is composed of decomposing leaves, another chemical reaction. Humus, which is essential to the soil, balances out the presence of carbon and nitrogen ratio of the soil. It can also retain, remove or lower concentrations of pollutants present in the soil (Royal Society of Chemistry,
