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 ...
The traditional study of plants is the science of botany. [123] Basic biological research has often used plants as its model organisms . In genetics , the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance , [ 124 ] and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their ...
They generally provide bottom heat (maintained at a particular temperature) and high humidity, which is essential in successful seed germination and in helping cuttings to take root. In colder climates they are sometimes used for plants like peppers and sweet peas which need warmer environments (about 15°C, for the plants listed) in order to ...
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Epigeal vs. hypogeal germination. Hypogeal germination (from Ancient Greek ὑπόγειος [hupógeios] 'below ground', from ὑπό [hupó] 'below' and γῆ [gê] 'earth, ground') is a botanical term indicating that the germination of a plant takes place below the ground. An example of a plant with hypogeal germination is the pea (Pisum ...

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.
The latter authors state that the sprouting of cereals has been reported to decrease levels of phytic acid. Similarly, Shipard (2005) [26] states that enzymes of germination and sprouting can help decrease the detrimental substances such as phytic acid. However, the amount of phytic acid reduction from soaking is only marginal, and not enough ...
