Abstract An experiment was conducted to determine the effect of the allelopathic compounds of Encelia Farinosa (brittle bush) on desert native annuals and non-native seed germination. The experiment was set up by putting native wild flower seeds in six Petri dishes and lettuce seeds in six different dishes. To three of each dish containing the different seeds‚ water was added as a control. To the three other dishes‚ a prepared brittle bush tea (filtered ground brittle bush leaves and water) was

Radish Seed Lab Report Problem: What caffeinated drink (monster‚ coffee‚ or green tea) will the radish seeds grow in the best form over a nine day period? Hypothesis: If the radish seeds put in the dish with the drink Monster‚ then the seeds will grow faster because of the amount of energy given to them. The amount of caffeine in Coffee is much greater than the amount in green tea and Monster‚ but neither coffee nor green tea contains any extra type of an energy booster like the Monster does.

potential performance of the seed or seed lot during germination and seedling emergence (Perry‚ 1978). Rapid and uniform germination are among the properties of vigorous seeds (Argerish & Bradford‚ 1989). Low vigour adversely affects such factors as optimal emergence‚ stress resistance and uniform growth of emergent seedlings (Patrick et al‚ 2000) and is thus of great economic importance. Seeds‚ which grow well under the ideal conditions of the germination test‚ often do not perform so well when planted

phytoremediation. The minimum amount of lead (0 mg/gm) was found in plant treated in 0 % concentration of lead acetate and maximum amount of lead (0.0011 mg/gm) was found in plant treated in (0.6%) concentration of lead acetate. The percentage germination for control‚ 0.2‚ 0.4‚ 0.6 percent lead acetate treated seedling was 89%‚ 88%‚ 86.66% and 83% respectively. The length of shoot was found much less in plant treated in 0.6% concentration of lead acetate (10 cm)‚ as compared to the length of shoot

were observed for seven weeks. The percent germination and mortality rate‚ as well as the height (in cm) were obtained. Results showed that the control obtained the highest germination rate and average plant height while the lowest was obtained by the treatment which used the highest irradiation rate (50 kr). From the results it could be concluded that increasing the radiation rate can inhibit the growth in terms of height and lower the percent germination by inducing mutation. As the exposure of the
