Does scarification affect the rate of germination?
Scarification can actually have a positive effect on the rate of germination for certain seeds. By nicking, scratching, or softening the seed coat, scarification can help water and oxygen reach the embryo more easily, thus promoting germination. It can be especially helpful for seeds with hard or impermeable seed coats.
Do sunflower seeds need scarification to germinate well?
No. The common sunflower does not require scarification; they have a sufficiently high germination rate without cracking the hull.
Scarification technique in breaking dormancy for Mimosa diplotricha?
Scarification is a method to break seed dormancy by making a small cut or abrasion on the seed coat, allowing water to penetrate and kickstart germination. For Mimosa diplotricha seeds, scarification can be done by using sandpaper to gently rub the seed coat, or by soaking the seeds in warm water for a few hours before planting. This process helps mimic natural conditions that would trigger germination in the wild.
What is the effect of scarification on jute mallow seeds?
Scarification can enhance germination in jute mallow seeds by breaking down the seed coat, making it easier for water and oxygen to penetrate the seed and kickstart the germination process. This process can help improve the overall germination rate and speed up seedling emergence.
Does the size of the apple determine the amount of seeds it has?
No. The number of seeds is determined long before the apple reaches its maximum size. It depends on the number of ovules in the flower, and the number of seeds that are fertilized and which then mature. Seed counts in various fruit varies from species to species as well as cultivar to cultivar
Why do seeds have different colours?
Seeds have different colors due to the presence of natural pigments, such as anthocyanins, carotenoids, and flavonoids. These pigments play a role in seed protection, attracting seed dispersers, and aiding in germination. The color of a seed can also indicate its nutrient content or maturity.
Does the type of apple affect the number of seeds it has?
Yes, the type of apple can affect the number of seeds it has. Different apple varieties have varying genetic traits that can influence seed production. Some apple varieties are known to have more seeds than others due to factors such as genetic makeup, pollination, and growing conditions. Therefore, it is possible to observe differences in seed count among different types of apples.
Does acid rain affect germination of seeds?
Yes, acid rain does affect germination of seeds by mixing in with the soil and damaging the seed coating.
