Question

An international code of botanical nomenclature was first proposed in year
A)1930
B)1830
C)1913
D)1813

Answer 1

Hint: It is the set of rules and recommendations dealing with the formal botanical names that are given to plants. It was first proposed by Sprague, Hitchcock, Green but was accepted in 1961. During the 12th International congress, Leningrad 1975, ICBN was revised.

Complete answer:
The International Code of Botanical Nomenclature (ICBN) is the set of rules and recommendations which mainly deals with the formal botanical names that are given to various plants. Its motive is that each taxonomic group of plants has only one correct name that is accepted worldwide. It was first proposed by Sprague, Hitchcock, Green (1930) but was accepted later in 1961. The revised form was republished in 1978.

Principles of International Code of Botanical Nomenclature, (ICBN):

I. Botanical nomenclature is independent of zoological nomenclature. The code applies equally to names of all the taxonomic groups which are treated as plants.
II. Application of names of taxonomic groups will be determined by means of nomenclature types.
III. The nomenclature of a taxonomic group is based upon the priority of publication.
IV. Each taxonomic group with a particular circumscription, position, and route can bear only one correct name.
V. Scientific names of taxonomic groups will be treated as Latin regardless of their derivation.

Hence, the correct answer is option (A)

Note: The ICBN applies not only to plants, as they are now defined, but also to other organisms traditionally studied by botanists. This includes blue-green algae, fungi and slime moulds. It also includes photosynthetic protists and taxonomically related non-photosynthetic groups.
