SMOG’S INFLUENCE ON THE GROWTH OF SPROUT LAWN

The following paper was presented by students (Oscar Gerardo Suarez Parra, Ariadna Monserrat Alvarado Ávila, Saul Salvador Cabañas García, Sandra Puente y María Teresa Laguna Quevedo) who are training as teachers in higher education center of LaSalle, in the course of Natural Sciences, Primary School.

A research protocol using Gowin’s Vee was followed. Then carry out part of the result is presented.

Whenever we talk about natural environments we refer to two types of factors, biotic and abiotic factors; abiotic factors are those that have no life, but that favor life and are essential for this, as is the soil, temperature, heat, water, air, pH, etc .; and biotic factors are those living organisms that interact with each other and also with the abiotic.

In any habitat these factors are essential, both aquatic and terrestrial, it is important to note that not always these elements or factors are in pure conditions generally abiotic factors are altered by human action ceases to be stable and often limiting the growth or development of biotic factors.

Abiotic factors are the main brakes growing populations. These vary depending on the ecosystem of every living being, such as bio major limiting factor in the desert is water, while for the living areas of the deep sea is the brake light. The reason why we have determined that the objective of this study was to determine the factors that limit the distribution of organisms and their abundance or scarcity, is to feel the influence of these limitations that we mentioned at the top.

When asked on several sources we found that plants have a special sensitivity to most air pollutants and suffer significant damage, which can manifest in different alterations in the life cycles and development of plants thanks to the action of gases such as sulfur dioxide, carbon monoxide and fluorine compounds <what we call smog> acquiring the plant pale green, yellow or the appearance of green spots or stunting it. Indeed the greater the imposition of the plant to these gases, the damage is more acute.

Hence the concern then check the effect of these gases on plant growth and the influence of abiotic factors have on them; thus raising the question that our research will lead to be our motivation for this work:
¿Will cause smog stress or inhibition in the growth of sprouts ?.

In 1905 Blackman developed his “Theory of optimal and limiting factors”, which were considered the rates at which the reactions were verified. The theory stated that “when a process was conditioned with respect to its speed, by a number of factors, the rate at which it developed was limited by one who acted more slowly. Lundegardh (1931), in their research also noted that with increasing intensity decreases a factor in their relative effect on plant growth. This principle, called sometimes “law of relativity” evidence of a correlation between environmental factors and crop yields.

Livingston and Shreve (1921) in his concept of “physiological limits, suggested that” for every vital function zero no maximum and a minimum with respect to any conditioning factor, beyond which ceases to function. “Moreover, for each different climatic area appears to have a corresponding type of vegetation. Considering the principle of fundamental importance in the study of the distribution of plants.

Another law that will serve to deepen and analyze the results obtained is that of Machado which states that there is a great possibility that the plants or sprouts can show immediate adaptation to the new place where they are placed; these laws will help us build our experiment by comparing the theoretical with the practical.

Many people are really concerned about the ecological situation in which we find ourselves, many of the attitudes that we have or take about either care or neglect of it is due to personal and social ignorance about the interest in conducting this project is to first conduct this experiment simply and locally (with the group), to multiply then with the students and also with the families and thus be creating awareness of the preciousness of abiotic factors such care the nature and balance between the two (abiotic and biotic) and at the same time other than that we use to create conscience is easy to perform, feasible and favors nature (planting and caring for seeds).

Methodological Process

For the preparation of this research was necessary after defining the experiment, document ourselves about to discover the elements that are present in the text, conduct experiments l which is as follows:

-Produciremos Smog in a glass jar. He poured vinegar He added a match on and quickly sealed with a piece of foil .. -Later Opening this bottle against the opening of an identical bottle containing germinated grass seed and observe, record and analyze the results will be placed.
For this work the following materials are needed: vinegar Germinated grass seed 2 small glass vials A piece of aluminum foil matches Logbook

Hypothesis

Assume that when performing the experiment will be appreciated that turf growth decreases after exposure to smog, discoloration presenting later on leaves due to the toxicity of the components of smog (the sulfur released by reacting with phosphorous on own vinegar) components.

Conclusion

The completion of this research report despite little time to develop, favored the interest in the development of the experiment with the research question.

This work allowed us to find sources that will sustain our words and ideas, in theory our work is done, must discover through experimentation if so, observing and analyzing the results; and draw our own conclusions again. It was not easy preparing it though because on smog much information, there is little information about the theories or laws that talk about it or we manage information on the effect this has on seeds and plants.
