What are the two most important systems of classification?
Botanical and Horticultural Systems
It is the most important method of classifying plants since it is
based on as many characters as possible and known genetic relationships.
Botanical Classification
What are the four classes of plants based on the botanical classification?
spermatophytes
thallophytes
bryophytes
pteridophytes
What is the most agriculturally important plant class, since all crops in cultivation today belong to this group?
Spermatophytes
Spermatophytes are further divided into two subdivisions such as:
Gymnosperms
Angiosperms
These are plants that have naked seeds, like pine trees.
Gymnospermae
These are plants that have seeds enclosed with certain structures
Angiosperms
This system of classification is highly artificial, arbitrary, and is not mutually exclusive.
Horticultural Classification
What are the four major groups that belong to the horticultural classification?
Plantation Crops
Vegetables Crops
Fruit Crops
Ornamental Crops
These are crops that bear edible fruits that are usually consumed fresh, either at the full or partially ripe stage.
Fruit Crops
These crops require primary processing to convert the raw produce into saleable and storable form.
