A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe. [2] [3] Many of these terms date back to the earliest herbalists and botanists, including Theophrastus.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Plant description is a formal description of a newly discovered species, usually in the form of a scientific paper using ICN guidelines. The names of these plants are then registered on the International Plant Names Index along with all other validly published names.
Other fields are denoted by adding or substituting the word botany (e.g. systematic botany). Phytosociology is a subfield of plant ecology that classifies and studies communities of plants. The intersection of fields from the above pair of categories gives rise to fields such as bryogeography (the study of the distribution of mosses).
In botanical nomenclature, a form (forma, plural formae) is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. [1] If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the ...
Courses are at undergraduate and graduate levels and include B.Sc. (Hons) Agriculture (Agri. Extension Major); M.Sc., M.Sc.(Hons), and PhD. A quarterly agricultural journal is published for farmers. [ citation needed ] On 14 August 2012, the institute started broadcasting on FM Radio 100.4 to disseminate agricultural innovations among farm ...
The first version (1953) was published by the Royal Horticultural Society as a 29-page booklet, edited by William Stearn. [9] Following the structure of the Botanical Code , the ICNCP is set out in the form of an initial set of Principles followed by Rules and Recommendations that are subdivided into Articles.
