Intraspecific Competition of Mung Beans

Investigating the effect of intraspecific competition on the growth of mung beans

Introduction

When plants reproduce, size is highly correlated with reproductive. The struggle for reproductive survival among plants is the struggle to grow in the face of competition from neighbours. So the question this experiment asks is how competition affects the growth of plants. A plant growing in a nutrient-abundant environment free from competition will exhibit maximum growth.
One way to address this question is to grow the organism alone in controlled environment and grow organisms in another controlled environment in the laboratory. Such laboratory experiments can manipulate population density as well as environmental factors such as nutrients and light.
In the experiment, density (ie. no. of organisms) will be varied. We will use mung beans, as the experimental units. In the experiment, plants will be grown in monospecific plots.
Growth and development of plants occurring in soil habitats may be determined by a combination of abiotic and biotic factors. Competition affects biomass production mung beans in soil. Increases in plant density may lead to an asymmetric frequency distribution of plants in which there are a few large individuals and numerous small plants or to a symmetrical competitive response in which all individuals have an equal decline in biomass production. In the case of asymmetric distribution, size variation among plants generally increases when there is competition for light because larger individuals may reduce light available to smaller individuals and thus suppress their growth. Smaller individuals might be lost due to high density-dependent mortality, because mung beans have relatively high light requirements.
Intraspecific competition is reported to reduce biomass production in mung bean plant in both field and laboratory investigations. Although much is known about the whole plant response to intraspecific competition, little is known about the

    Abstract The Seeds of Mung bean, wheat, and silver beet were tested in environments of differing salinities to note down if high salinity environments were worse for the seeds. It was found that generally lower concentrations were better for germination then higher concentrations. Despite this, the hypothesis was not completely supported as in wheat and silver beet the second concentration had a higher rate of germination than the control and in all instances the highest concentration had a higher…

    Sprouts Put 1/3 - 1/2 Cup of seed* into a bowl or Sprouter. Note: Mung Beans are grown in China by farmers - often with little machinery. After harvest they are left to dry on gravel roads - so they are dusty. So: Prep before Soaking, by running water through them until the exiting water runs clear. It doesn't take long - they aren't very dirty nowadays. Is that not cool?! The dust/dirt you just washed off of your Mungs was part of a Chinese road!!! Add 2-3 times as much cool (70°) water…

    Measuring the Effect of Density on Growth of Mung Bean (Vigna radiata) Plants Wylliam Wagoner1 1 Population and Community Ecology, Butler University, Indianapolis, Indiana 46208, USA ABSTRACT For this experiment, we set out to find if density and time had an effect on growth of mung bean plants. We decided to test evidence of growth by measuring plant biomass. We measured the biomass each week for four weeks of plants grown at different densities. We found that density had an overall effect…

    Effect of Salt Solution on Mung Bean Growth Hypothesis: If the Mung Beans are watered with a higher salt solution, then less Mung Beans will sprout. John Murrell 9-18-12 Magnet Biology Introduction This experiment was done to test the effect of salt solution on mung bean growth. Generally when you grow mung beans you soak them in water for eight to twelve hours and then put them in a separate container to sprout. Since this experiment was not monitored every hour, and had limited…

    Summary of Findings 1. Music affects the growth of Mung beans. As established in the experiment and based on the data gathered, music has a great effect on the growth of Mung beans. The varying degree of effect is dependent on the type or tempo of music to be played. 2. In general, music helps in the growth of plants. It hastens the growth of plants. As we conducted and observed our experiment, we noticed that classical music helps the Mung beans' growth. Plants exposed to rock music grew slower…
