Turnips are a biennial plant, taking two years from germination to reproduction. The root spends the first year growing and storing nutrients, and the second year flowers, produces seeds, and dies. The flowers of the turnip are tall and yellow, with the seeds forming in pea-like pods.
The prairie turnip is more nutritious than most root crops, containing about 7 percent protein, more than 50 percent carbohydrates, and is rich in vitamins and trace minerals. Particularly important was the vitamin C content of 17.1 milligrams per 100 grams as the winter meat-rich diet of the Plains Indians was often deficient in vitamin C. [ 8 ...
Over time, seeds lose viability, which is the ability to initiate metabolic activity, cellular growth, and germination. Seeds have many cells and tissues that die over time, [1] and these deaths can be delayed or increased by environmental conditions the seed experiences. Very generally, small seeds, especially from weedy species and annuals ...
Bottom heat is recommended, as the seeds require warm temperatures to germinate, so the pots will need to be kept in a warm place. Jícama is unsuitable for areas with a short growing season unless cultured in a greenhouse. Growers in tropical areas can sow seed at any time of the year.
The main harvest time starts in July and lasts until September. Due to the requirement of a dormancy period, it is almost mandatory to sow the seeds directly after harvest for the upcoming season. Because of this, and due to the low yield and poor germination of the seeds, Chaerophyllum bulbosum has hardly spread in commercial cultivation. [16]
The time it takes for germination depends on the type of seed and their environment. Typically the seeds are first rinsed to remove soil, dirt and the mucilaginous substances produced by some seeds when they come in contact with water. Then they are soaked for from 20 minutes to 12 hours, depending on the type and size of the seed.
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
