Ameirs SM, Farah OR. 1976. Cytological effects of pesticides VIII. Effects of the carbamate pesticides “IPC”, “Rogor”, and “Duphar”, on Vicia faba. Cytologia. 41, 3-4: (597-606).

Topic—Pesticide Effects, Meiosis, Yield

Context
This study investigate the effects of common pesticides, “Rogor”, “Duphar”, and “IPC” (o-isopropyl-N-phenyl carbamate), on Vicia faba, also known as the broad bean.

The objectives of this study were to determine the effects of three different pesticides on 1) meiosis, 2) pollen viability, 3) and the yield and root-mitosis of Vicia faba plants for three generations.

Methods critical to this study were: 1) soaking seeds in the three different pesticides, 2) spray treatments of three different pesticides, 3) permanent root-tip squash preparations stained after Feulgen technique.

Major results from this research include:
1. “Spraying plants at the flowering stage with “IPC” affected the highest percentage of abnormal PMCs” (Ameirs and Farah 1976).
2. Pesticide did not affect pollen viability
3. Seeds that were soaked in “Rogor” and “Duphar” showed a decrease in the average number of pods and weight of seeds/plants. This occurred in the 1st generation only.
4. Spraying plants with “Rogor” or “IPC” showed in increase in the average number of pods/plant only in the 2nd generation. This increase decreased in the 3rd generation
5. “The transmission of chromosomal aberrations to the following generations is very low after both seed-soak and spray-treatments” (Ameirs and Farah 1976).
6. All three pesticides have no harmful effect on the yield.

Synopsis
Spraying plants with “IPC” caused a high percentage of abnormal PMCs. “IPC” also caused tetraploid PMCs. Pesticides used in this study had no harmful effect on the yield. If an increase or decrease in yield occurred, it returned to normal in the following generation.

Relevance: This study discusses the effects of pesticides on Vicia faba which relates to our

    Allelopathy Lab Report

    • 904 Words
    • 4 Pages

    The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds, for sunlight, and nutrients in order to germinate. In order to win dominance over other seeds, and reduce competition, plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants such as leaves, roots, stems, or fruits, but not limited to just the plants. These toxic chemicals can also be found in the surrounding soil, to prevent other plants or seeds from absorbing proper nutrients to stimulate growth. Groups will test…

    We were given 32 seeds in total, 16 for the control group and 16 for the experimental UV-C group. We obtained two 16 celled growing Styrofoam containers. We then placed a wick into each cell so water can travel from the source into the soil. We then added potting mix into the cells filling them up half way. Then, two fertilizer pellets are added and covered with more soil and compressed. One seed was added into the 32 individual cells and more soil was placed over the seeds. The seeds were then watered until the soil was fully saturated. All 32 plants were placed on a watering tray and placed under fluorescent lighting. The newly planted seeds will remain under constant fluorescent light without any experimentation until germination completes and there is visible plants growing from the soil of every…

    Seeds must protect themselves until they are in the right conditions for them to grow. Until the conditions are right, seeds are dormant and appear dead and it is difficult to tell if they are actually alive (Germination). The embryo within a seed will eventually die while it is dormant if it doesn’t begin germination by a certain time. Depending on the seed, the length of viability can be a few weeks, to hundreds of years (Germination). Germination begins when dormant seeds are under…

    For each treatment, we obtained two planting trays with cell flats- in which one corner cell was cut out to water the plants. We filled all cell flats with the fertilized soil and used forceps to place one seed with 3-4mm deep in the middle of each cell. After all trays of cells were planted, we brought these trays in a growth room and watered the plants. In the growth room, the amount of light, the temperature, and the humidity was kept the same for both control and experiment treatments. By using a ruler, we poured water into the trays up to 3 cm through the open-corner cells. We then watered the plants up to 1cm every Monday and Wednesday and up to 3cm every Friday. We also made a log of water that recorded who watered, how much water, and observations of the…

    This experiment is designed to test the allelopathy of two different treatments, Eucalyptus (Eucalyptus cinerea) and Lemon (Citrus limon). The two treatments will be tested on radish seeds (Raphanus sativus) to investigate the effect of the treatments on the germination of the radish seeds. Allelopathy is the beneficial or harmful effects that one plant has on another plant by the release of chemicals. Allelopathy studies the interactions among plants, fungi, algae and bacteria with the organisms living in a certain ecosystem, interactions that are mediated by the secondary metabolites produced and exuded into the environment (Francisco A Macías, José MG Molinillo, Rosa M Varela, Juan CG Galindo 2007). The plants use allelotoxins, which are an allelochemical produced by one plant that is toxic to another plant, to help them compete for space. Often these chemicals inhibit seed germination and root growth of young neighboring plants with less effect on mature plants (Shimabukuro and Haberman 2006).…

    This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other", and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1)…

    We allowed the plants to sprout for two weeks prior to applying our first treatment of nitrogen fertilizer. The seeds are watered once daily and kept in a controlled environment (greenhouse). After two weeks we applied our first treatment of nitrogen fertilizer to 5 of the 10 pots. As we applied treatments to the plants we labeled the ones we applied nitrogen to. We added .5 ml of nitrogen only fertilizer to 5 pots and placed them back in the controlled environment. We continued to reapply the treatment once a week until the experiment was complete. Each week before applying the nitrogen fertilizer we measured the plants in centimeters from the rim of the pot to the highest point of the plant. We kept records of the plant heights to analyze the data at a later time and compare week to week growth.…

    Household chemicals such as Windex, a glass cleaner, are known to be harmful to humans but if they affect plant growth could be an interesting experiment. Our experiment consisted of different levels of Windex mixed with water and given to Brassica Rapa plants in order to grow. Are results showed that Windex barely had an effect on the plant growth and the plants showed steady increase in growth. In conclusion, our experiment did not assure that Windex add a boost in plant growth but we did find that small, insignificant amounts of Windex mixed with water were able to ingested by the plants.…

    The increase in desire for perfect produce, drives the need for pesticides today. Much debate of the effects of chemicals used on commercial crops and overall long term effects on humans is an increasing concern. With the increase in advertising of organic produce, many standards of farming have been criticized. Many are claiming a large increase in risk to humans for consuming commercially grown produce, because of the chemicals used to manage such a large volume of crops. There have been many debates of the actual risk of pesticide consumption. With advancing technology and farm equipment, many types of chemical sprays and powders have been used. The actual effect of these pesticides and long term exposure can be harmful to human health.…

    Honey Bees Research Paper

    • 1244 Words
    • 5 Pages

    For decades, the metaphorical story of the “Birds and the Bees” has been told to children in order to explain sexual intercourse. Since honey bees are an important part of the fertilization process among plants, also known as pollination, this story is a good way of speaking openly about the subject without using technical terms. When a honey bee lands on a flower, their feet slip into little grooves that hold pollen sacks which they carry with them until they land upon another flower. Once landing on another flower, the pollen falls out of the sac enabling the plants to fertilize and sexually reproduce. For this reason, agriculturalists welcome the presence of honey bees among their crops. National Geographic reported “an estimated 14 billion U.S. dollars in agricultural crops in the United States are dependent on bee pollination.” But within the past several years beekeepers have found a high population of weakened and dying honey bees. The last report of a similar issue occurring amongst the honey bees, was due to a parasitic bug called the varroa mite, but this time researchers have not found any such mite or pest and are beginning to suspect that the use of pesticides are the cause of this bee epidemic. The following research here will show how chemical pesticides are harmful to the environment, animals, and humans…
