extracts obtained from mango leaves inhibited seed germination of radish and sand fescue‚ and inhibited seedling growth of root and shoot growth of radish‚ rapeseed‚ sand fescue and crabgrass (Figure 1 and 2). The extract obtained from 0.03 g dry weight of mango leaves inhibited 20 and 50 % germination of radish and sand fescue respectively‚ on day 4 (Figure 2). The extract obtained from 0.03 g dry weight of mango leaves inhibited the root growth of radish‚ rapeseed‚ sand fescue and crabgrass by 9.03

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

that is commonly used for lumber and reforestation projects. However‚ based on studies‚ it is shown that the mahogany tree has inhibitory effects that affect adjacent growing plants. This is made possible chemically and is referred to generally as allelopathy. This study aimed to determine is S. macrophylla had any adverse effects to the growth of plants in close proximity to it. The researchers selected three mahogany trees and planted six plots of differeing distances with each plot containing ten

competition between plants for water and sunlight will affect their growth. To do this we will set up two pots with soil in them‚ one will have a radish seed inside and the other will have a radish seed surrounded by crest seeds. The independent variable will be the amount of seeds in each pot and the dependent variable will be the height of each radish at the end of the experiment. The constant factors will be the amount of sunlight each pot receives; this will be done by placing both pots by the

Introduction Seed germination and growth are influenced by many factors. Some of these are the environment‚ light quality and moisture availability. Other factors which may influence seed germination are a result of the environment surrounding the seed‚ like alleleopathy. In this experiment we are going to study the 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

Observation of the germination of Cherry Belle radish seeds in different temperatures Problem: In which temperatures‚ 5°C or 47°C‚ will the cherry belle radish seeds germinate better over a 9 day period? Hypothesis: If temperatures of 5°C and 47°C are used on cherry belle radish seeds to study which temperature will be better for the germination of the seed for 9 days‚ then 47°C will be the best temperature because 5°C would be too cold for the seeds to grow in.

are about a million different kinds of seeds in our world with all of the different types of plants that we have. One type of seed that takes between three to five days to germinate is a daikon radish. The radish (Raphanus sativus ) originated from China. It was commonly seen and eaten by the people of Egypt long before the Egyptians started to construct their very own pyramids. Later on‚ radishes became a common vegetable to eat in Greece‚ and since the radish meant so much worth for the Greeks‚ they
