The 1881 American Household Cyclopedia advises that turnips can be grown in fields that have been harrowed and ploughed. It recommends planting in late May or June and weeding and thinning with a hoe throughout the summer. [9] As a root crop, turnips grow best in cool weather; hot temperatures cause the roots to become woody and bad-tasting.
The prairie turnip takes 2 to 4 years to grow from seed to mature root. The long period required for maturation probably limited the success of any efforts the Indians made to cultivate the plant. Garden plantings have been made by scientists to evaluate the potential for domestication. [11] [12]
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.
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.

Germination of seedlings raised from seeds of eucalyptus after three days of sowing. In agriculture and gardening, the germination rate describes how many seeds of a particular plant species, variety or seedlot are likely to germinate over a given period. It is a measure of germination time course and is usually expressed as a percentage, e.g ...
