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 ...
Prefix meaning "near or toward"; also meaning "added to". [13] adaxial Surface of an organ facing toward the organ's axis, [13] e.g. the upper surface of a lateral organ such as a leaf or petal. Contrast abaxial. adelphia. pl. adelphiae
The broadest definition includes handheld power tools, but in general usage, the term implies huge motorized machines, particularly tractors and the many types of farm implements which they tow and/or supply power to. The mechanization of agricultural tasks is a defining element of industrial agriculture.
Red mangrove seeds germinate while still on the parent tree. In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow cormlets in the axils of their inflorescences. These fall and in favourable circumstances they have effectively a whole season's ...
The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth. The germination rate is the length of time it takes for the seeds to germinate. Germination percentages and rates are affected by seed viability, dormancy and environmental effects that impact on the seed and ...
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo.This is a pertinent stage in the plant life cycle that is followed by dormancy and germination. [1]
A seedbed of rice plants. A seedbed or seedling bed is the local soil environment in which seeds are planted. Often, it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field.
This is epigeal germination. However, in seeds such as the broad bean, a leaf structure is visible on the plumule in the seed. These seeds develop by the plumule growing up through the soil with the cotyledons remaining below the surface. This is known as hypogeal germination.
