INTRODUCTION A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR‚ 30kR‚ 50 kR‚ and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller

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.

The purpose of this lab was to investigate how size of seeds impact respiration rate. It was hypothesized that bigger seed will require more oxygen because more energy is needed to sustain the seed’s homeostasis. For this experiment 4 groups was set up with 0.5 mL worth of the following seeds: peas (1) ‚ black beans (1)‚ radish seeds‚ and glass beads (control). The black bean served as the biggest size‚ peas were medium‚ and radish seeds were the smallest. After setting up the microrespirometer and

Factors affecting seed and seedling vigour Seed vigour is a term encompassing the sum total of those properties of the seed that determine the 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

Introduction 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

purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides the energy to

Radish Radishes are only moderately cold hardy and need about 6 weeks of favorable growing conditions to produce sufficient biomass to achieve most potential benefits. Lastly‚ be forewarned that rotting radish residues produce a powerful rotten egg-like odor‚ particularly during winter thaws. Radish Seedlings and Sprouts Radish seeds don’t have to be planted‚ they can be grown in a sprouter and eaten just as you would eat mustard and cress or any other sprouted bean or seed. As some of my
