NATURAL LONGEVITY OF TREE SEEDS. The period for which seed can remain viable without germinating is greatly affected by its quality at the time of collection, its treatment between collection and storage and the conditions in which it is stored. According to Harrington (1972) one of the two main factors influencing seed longevity is seed moisture content. Seeds are hygroscopic and their moisture contents come into equilibrium with those of the atmosphere. Nevertheless, seed longevity varies…
Spinach (Spinacia oleracea) : is an edible flowering plant in the family Amarathacea native to central and western Asia. It is an annual plant (rarely biennial), which grows up to 30 cm tall. Spinach may survive over winter in temperate regions. The leaves are alternate, simple, ovate to triangular, and very variable in size from about 2–30 cm long and 1–15 cm broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem. The flowers are inconspicuous,…
things will come out a lot smoother. Why trim Hedges: There are three big reasons to trim your hedges. First, repeated trimming trains the plants the same way your hair gets trained by being combed the same way over and over. Second, we improve the health of the plant by trimming off dead sections that can invite insects or disease into the rest of the plant. Third, believe it or not, trimming hedges actually encourages them to grow. When to trim: The best time to trim your hedges in the…
hypothesis is that the presence of broccoli will have a positive effect on germination of plant seeds. In my results, I saw that the hypothesis was in my favor because the stems of experimental groups were much longer then the stems of control group. Other works that have been done by scientist which relate to my experiment include Alleleopathy. Alleleopathy is “any direct or indirect harmful or beneficial effect of one plant… on another through prediction of chemical compounds that escape into…
Conclusions: In conclusion, sugar didn’t make the plants grow faster it made them grow slower. Although the plants with added sugar at the end started to grow faster, the heights for the 1 tsp of sugar plants doubled in size. I think this is because the plants needed to get used to the sugar and once they did it acted as a steroid and made them grow faster. I think to prove my hypothesis I needed more time to carry out the experiment to see if the sugar acted as a steroid or if in the end it…
will have the fastest growth. Following the blue light, red should show the second most efficient color for a plants growth. Therefore, the control light will be the least effective out of those three. This project was chosen because of interest of growth of plants inside instead of outside. The solutions to this experiment might help somebody who doesn’t have any outdoor space to plant. Materials and Method: 30 plastic cups, 5 red transparent folder dividers, 5 blue transparent folder…
with a damp paper towel. Once the seed germinates and the plant has begun to sprout, move the seeds to four separate pots, and add soil. Once the plants have begun to sprout take the measurement of each plant and record your data for day zero. Next, take three glass containers of greatly varying volumes (41,4185cm3, 2,250cm3, and 602cm3 were used). Before the plants are placed underneath these containers, give 15ml of water to each plant. The numbered pots will remain underneath these three…
Joshua trees are relatively fast growers for desert plants. Seedlings will grow at an average rate of 7.6 cm (3 inches) per year in their first ten years. Seedlings will then slow to 3.8 cm (1.5 inches) per year. Many desert plants need to grow to a height of about 1 meter to escape high ground temperatures and shading of adjacent plants, which will negatively affect their growth rate. Joshua trees can exceed 3 meters, which allows them to escape these pressures. DeFalco et al. believes this…
Oaks, which is where President Dave McFadden and past Manchester University presidents have lived. Some of the significant problems that are hitting Tall Oaks are things like: invasive plant and tree diversity and leaving the snags up. Once a upon a time, Manchester College (now university) was adding trees and plants to the grounds; most were foreign and invasive trees, like the Cherry Blossom tree. There were close to a thousand saplings of invasive trees…
Maple trees are glorious trees to have in your yard because they are so large and strong. However, there are a few tree diseases that seem to occur more often with maple trees that you need to be aware of. Awareness of these diseases can help you treat and save your maple trees should Maple Wilt Maple wilt is caused by two different types of fungi, Verticillium dahlia and Verticillium alboatrum. These fungi reside in the soil and starts by working its way into your Maple tree’s root system.…
