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

ABSTRACT To determine the effects of gamma radiation in inducing mutation on the growth of corn (Zea mays)‚ an experiment using corn seeds exposed in to different rate of radiation (0kr‚ 10 kr‚ 30 kr‚ and 50 kr) was done. Four treatments were prepared using 10 seeds from each of the following different radiation rates. The seeds were planted and were observed for seven weeks. The percent germination and mortality rate‚ as well as the height (in cm) were obtained. Results showed

Aim: To investigate the effect of one environmental factor on the phenotype of pea plants Background Information: Pea seeds are available with identical genetic information for height - tall or dwarf peas. These seeds can be used to demonstrate the effect of the environment on the final height of the pea plants. Tall or dwarf peas can be grown in identical conditions where all variables are kept constant apart from one environmental factor. Any differences in the height of the pea plants will be

The Tap Water allowed the radish seeds to germinate with in the first 48 hours. In the petri dish labeled tap water‚ 10 out of 10 seeds sprouted into plant growth as seen in Figure 5.1. The radish plant growth within the tap water petri dish grew so well it started to lift the lid off the dish. The results from the Acid Rain (50% vinegar solution) did not allow any radish seeds to germinate. There were never signs of seed germination while observing the seeds over a three week period. In the petri
