1, corn seed
Corn seeds are propagators with the ability to grow into plants, which are formed by ovule pollination and fertilization. Corn seeds consist of seed coat, embryo and endosperm. There are four kinds of maize seeds: conventional seeds, inbred lines, single cross seeds, double cross seeds and triple cross seeds. Hybrid corn seeds are the most common land for farmers in the market. The future trend is transgenic corn seeds.
2. Are corn kernels seeds or fruits?
Corn kernels are fruits and belong to a kind of caryopsis. This kind of fruit is inseparable from seeds, so corn belongs to seeds. The shape of corn kernels is spherical or oblate. Most varieties of corn kernels are yellow when they are ripe. They should have sufficient nutrients in the process of corn growth, and pay attention to the prevention and management of diseases at ordinary times.
3. Similarities and differences between bean seeds and corn seeds.
Similarities: both kidney bean seeds and corn seeds have embryos and seed coats, and embryos all contain germs, hypocotyls, radicles and cotyledons. Difference: The number of cotyledons and sowing methods of kidney bean seeds and corn seeds are mainly different. Kidney bean seeds have two leaflets, which can be used for direct seeding or seedling transplanting, while corn seeds have/kloc-0 leaflets, which are basically direct seeding, and nutrients are stored in endosperm.
4. What shape is the corn seed?
The seeds of corn are the seeds on the corn cob, which are small, wedge-shaped and oval. Its seeds are composed of the outermost colorless seed coat, endosperm and embryo in the seed coat. There are many kinds of seeds, including conventional seeds, single cross seeds, inbred seeds, double cross seeds and triple cross seeds.
5. External characteristics of maize seeds
The shape of corn seeds is oval and U-shaped, and the seeds are the seeds on the corn cob. The new seeds look very shiny and full in shape. When planting, you need to prepare the soil first and break it up with tools. There can be no large pieces of soil. Corn also needs to be treated before planting. Some pesticides such as carbendazim or potassium permanganate can be added to corn seeds for seed dressing and disinfection.
6, the structure of corn seeds
Corn seeds are mainly composed of pericarp and seed coat, endosperm and embryo. The pericarp and seed coat are located at the outermost layer of the seed and are responsible for protecting the seed. The endosperm is located in the middle layer of the seed and is responsible for providing nutrition for the developing embryo. Embryo is located in the innermost layer and consists of cotyledon, embryo, hypocotyl and radicle, which will develop into a complete plant.
