Factors Affecting Seed Germination Research Question What is the effect of dark and light on the germination of radish seeds? Hypothesis I predict the seeds grown in the light will germinate twice as much as the ones grown in the dark. Materials/Setup Paper towels 2 petri dishes 10 radish seeds Water Plastic container A weight A folded piece of paper Procedure 1. Take a paper towel and cut out two circles that are the same size as the base of the petri dishes. 2. Wet

BIOL 1401 General Biology Laboratory Seed Germination Exercise Introduction Seeds are produced by the more advanced plant groups that we will study this semester – Gymnosperms and Angiosperms‚ which are grouped as seeded-vascular plants. While we often take seeds for granted‚ they are remarkable in their physiologies and very diverse in their structure and germination requirements. Seed biology is actually a separate sub-discipline in botany‚ with direct significance to the study of plant ecology

Maria Xena M. Montalbo Year III – St. Albert A. Problem/Objective The study’s objective is to apply radish extract as an alternative pesticide. Specifically the study aims to determine the effectiveness of radish extract in exterminating household’s pests such as ants. Furthermore‚ the study aims to create the most effective radish extract solution in terminating pests. B. Application The study’s product aims to be applied as a pesticide. It tends to provide an alternative for the current

Phytochrome in Lettuce Seed Germination Abstract This experiment was performed to determine the role of phytochrome in lettuce seed germination. In order to conduct this experiment three different types of Grand Rapids lettuce seeds were chosen: Waldmann‚ Concept‚ and Two Star. Each of these seeds were exposed to the following regulated courses of light exposure for ten minutes after they had imbibed for five minutes: Red‚ White‚ Far Red‚ and Darkness. It was hypothesized that the seeds would germinate

The researchers set a five point scale to determine the characteristics and properties of Paper Radish. The points from the respondents answer to each item over a five point scale are represented as follows: WEIGHTED MEAN SCALE VERBAL INTERPRETATION

needs to be able to live is seeds. Seeds provide a food source that is not from meat and herbivores are able to survive. Different seeds can from both plants‚ and fruits. When plants want to reproduce the plants make seeds that can be dispersed by air‚ water‚ or animals and the seeds that survive find a place in the ground to start grow. For some plants‚ the seeds are in protective shelling like fruits and pinecones. This extra protection layer is there to allow the seeds to make it new ground by animals

temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot more tail length compared to the ones in the incubator. In fact‚ the seeds from the incubator

Results The above results show the data collected after a week of measuring the biggest plant per bag. Each day the biggest radish plant in site A was measured and by day five the largest plant was 5 centimeters long‚ and had developed small green leaves. By the 5th day site B and D’s seeds showed no signs of growing and length remained at 0 centimeters. Site C and D’s superior seed both grew a total of 3 centimeters according to the 5th day measurements. Both the graph and table display the same results

The Radish seeds were planted in a pot‚ which contained soil from the garden and cow manure. The Radish was placed in an area similar to the black bean plant and watered daily. According to Yates Expert (n.d.‚ para. 3) radish plants like moist soil and by watering the plant in the evening this helped stop the soil from being dried out from the summer weather. By day eight the radish plant had germinated with more than one seed breaking through the soil. However‚ regular observations showed that

Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants
