Practical Research & Report Assessment. Allelopathy and interference and the effect they have on plant growth. Allelopathy occurs in plants. Many plants produce chemicals that may be harmful or beneficial to other plants. In some cases a species can produce chemicals that can prevent the growth or germination of another species. An example of this is Australian native plants such as Casuarinas and Eucalypts which produce allelochemicals that prevent competition of other plants. This is a form of

coffee concentration plants are exposed to the less growth‚ number of roots‚ and mitosis in each cell. Other things in nature that might affect the growth rate of plant cells are sunlight‚ water‚ space‚ temperature‚ nutrients‚ bacteria‚ weeds‚ allelopathy‚ insects‚ soil‚ etc. In areas where there are very few plants growing‚ the following abiotic factors may be affecting the plant’s ability to thrive as well as the rate of mitosis: light‚ water‚ soil‚ nutrients‚ space and temperature. The few plants

need their own space in order to obtain sufficient amounts of nutrients from the soil and sunlight. Plants‚ of course‚ are unable to move away. However‚ some plants use chemicals to keep other plants from growing too close. This process is called allelopathy. Some scientists believe that germinating radish seeds give off a chemical that interferes with the germination of other seeds. A few years ago‚ a group of scientists published a scientific paper that demonstrated that germinating radish seeds

INTERDEPENDENCE BETWEEN THE SPECIES INTERACTION BETWEEN PLANTS AND ANIMALS: Animals are depending upon plants for their food shelter and also for various things. ANIMALS HELP PLANTS IN DIFFERENT WAYS 1.Many animals are involved in the pollination in plants. 2.Fruits and seeds of many plants are dispersed by animals 3.Decomposers convert organic substances into inorganic substances so that plants can absorb them easily. SPECIES INTERACTION All types of relationship between organisms can

Results and Discussion The annual yield of different mixtures and or pure grasses differed over from one another over the course of the experiment. The three mixtures had a greater annual yield than pure grasses in all three seasons. White clover mixtures had similar yields in all seasons‚ however they were less productive than alfalfa mixtures in year 2 and 3. Also‚ grass yield in mixtures was greater than in pure cultures for all seasons despite its half-sowing density‚ and it was precisely greater

Some K-12 schools have begun requiring that all students learn coding as a means of encouraging the next generation of computer scientists and of fostering higher-order thinking. What does that mean for higher education? Here are four possibilities. 1. Colleges and universities may have a ready team of student developers to help spur innovation. Ellen Yu Borkowski‚ CIO at Union College in Schenectady‚ NY‚ said she is looking for innovative ways to involve students in multidisciplinary design

alleleopathy of garlic. Using the scientific method of inquiry‚ my group and I are experimenting if the volatility of the crushed garlic will affect germination and growth of the radish seeds. Hypothesis: The volatility of the garlic will accelerate the germination and growth of the radish seed! Experimental design: -Distilled water (3 ml per setup) -beaker -Scale -Masking tape -Filter paper -Garlic press - 2 Petri Dishes -Radish Seeds (25 seeds per dish) -1 clove of garlic (crushed‚ only
