There are numerous forms of radiation, including gamma rays, which can hinder the seed germination, root growth and shoot growth of a plant, and ultraviolet, or UV, radiation from the sun, which helps to feed a plant after it has germinated and reached the surface of the soil. However, overexposure to UV-B radiation from the sun can negatively affect the process of photosynthesis in plants, thereby reducing the plant's size, rate of growth and overall quality.Continue Reading
UV-B radiation can also negatively impact a plant's ability to fight off diseases and can actually make them more susceptible to plant disease. This is due to the increased radiation impairing the cellular division, as well as impairing basic biological functions within the plants. This effect of UV-B radiation can especially be seen in ocean and freshwater plant life. Plants within bodies of water that are located too close to the surface can be exposed to more UV-B radiation from the sun than was naturally intended. Many of these effects can also be seen in places like Antarctica, where the breakdown of the ecosystem has been so obviously noted.
Gamma radiation can hinder the rate of germination, root growth, shoot growth and photosynthetic properties and processes. The larger does of gamma radiation, the more damaging the effects. Gamma radiation has also shown to be responsible for the introduction of free radicals into some plant species.Learn more about Botany
Seeds typically do not require sunlight for germination because most of their nutritional needs for the germination phase of a plant's life are contained within the seed itself. Conversely, some seeds do require light to germinate. Although this is atypical, such seeds mustn't be buried in soil.Full Answer >
Soil temperature governs how quickly a seed will germinate and send out the radical, or first root, and the coleoptile, the shoot. When planted in cool soils, seeds will absorb water, but the germination process is halted. Warm soil releases needed nutrients and encourages root growth.Full Answer >
Grow an elderberry plant by first taking a cutting from a healthy wild elderberry plant, cultivating roots for the cutting in either soil or water using a root growth hormone if desired, and planting the elderberry plant in a location that has rich soil, ample drainage and has either full sun or partial shade. Give each elderberry plant approximately 8 feet of space on every side as they grow to be between 6 feet and 8 feet wide.Full Answer >
Light affects plant growth in three ways, including quality, quantity and duration. All of these must come together in the proper balance to ensure optimal growth of a plant.Full Answer >
