Effects Of Hot Water Treatment On Germination Of Acacia Falcata Seeds

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 with the organisms living in a certain ecosystem, interactions that are mediated by the secondary metabolites produced and exuded into the environment (Francisco A Macías, José MG Molinillo, Rosa M Varela, Juan CG Galindo 2007). The plants use

Our data recorded shows that the germinating peas did consume more oxygen than the non-germinating or the glass beads alone and that the cooler temperature did slow down the consumption of oxygen in the germinating peas. In both water baths the atmospheric pressure seemed to increase causing our reading to raise in our glass beads and non-germinating peas. This direct relationship in reading leads us to believe that the oxygen consumption in the non-germinating peas was minimal if any at all.

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

The germination process begins when water and oxygen are pulled into the seed by the seed’s coating. The embryo’s cells grow bigger as water and air

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

The purpose of this report is to analyze and illustrate the geographical origins of eragrostis tef along with details of its global dispersion. The common name of the crop in Ethiopia is tef. It was chosen for its cultural significance and it’s importance

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

Experiment 1 (Assignment 3): Using sciccors, leaves from the Geranium plant were cut (Plant A was the bigger leaf and Plant B was the smaller leaf). Then begin to heat up the hot plate to boiling temperature of 100℃. Next one beaker was filled with ⅔ of water and another beaker was filled with ⅓ alcohol. Place the beaker of water onto the hot plate until boiling. To speed up the boiling process put boiling chips into the beaker. Then put Plant A (the leaf exposed to air) into the boiling water for 3-5 minutes. After time is up, using tongs, place Plant A directly into the alcohol solution for another 3-5 minutes. When time is up, take out Plant A and place it into a clean petri dish. Once the plant is properly placed, cover the leaf completely

We have learned in classes that germination is different for all plants and I want to work with plants

In this experiment, my hypothesis was not supported. The hypothesis stated that acid rain would decrease the rate at which seeds germinate. The hypothesis is rejected due to the data which shows that the average sprout length of the control group is shorter than the experimental group. Although the experimental group grew taller and faster, the control group looked healthier. The control group’s sprouts were greener and stood up taller while the experimental group’s sprouts were a very milky-white green and leaned over some.

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

The purpose of this lab was to see if decaf coffee or regular coffee had a better effect on the germination of flax seeds rather than tap water. We hypothesized that the caffeine in the coffee would be a boost and increase the speed of the flax seeds germination because of caffeine's effect on the human body and how it energizes us.

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

Average annual precipitation of experimental site over last ten year was 1200 -1800 mm. Terminal leaf length, terminal leaf width, terminal petiole length, petal length, petal width, flower diameter, fruit length, fruit width has been measured in centimetres. Number of days from Julian Day (1st January) to 5% bud burst have been counted and expressed as days to bud burst. Similarly, number of days from Julian Day to 95% bud burst have been counted and expressed as days to end bud burst. Weight of ten representative fruits of different sizes has been recorded with the help of electronic pan balance and average is expressed as fruit weight (g). Volume of fruits has been measured by dipping the fruits in measuring cylinder and measuring the volume of water replaced by fruits. Fully ripe fruits were used to measure the pH of juice by pH meter. Total soluble solids at full ripe stage (ready to eat) have been measured with the help of the refractometer and expressed as

A study was conducted at Gomal University that tested the allelopathic effects of Eucalyptus camaldulensis L. on the germination and seedling growth of wheat. The leaves of E. camaldulensis trees were washed and dried and then filtered to create a one hundred percent solution as well as ten percent, fifteen percent, and twenty percent. These solutions were tested on twelve varieties of wheat. The results showed that there was a significant decrease in germination counts with increasing levels of Eucalyptus aqueous extract concentration. All twelve varieties of wheat were adversely affected by the twenty percent concentration of Eucalyptus extract. It was observed that there was a direct relationship between the number of normal seedlings and the extract concentration. The results suggested that the E. camaldulensis L. leaf aqueous extract could reduce normal seedlings even in low concentrations.
