CHARACTERISTICS OF HORTICULTURAL CROPS
Many have high water content, hence they are utilised mostly in their living state
There are many horticultural plants in the world. A lot of knowledge has been gathered on the plants. Classification makes summarisation of information on the plants possible hence serves time in information sharing.
It is a means of identification and communication on horticultural plants
There are two types of classification, which are natural and artificial.
Scientific plant classification falls under natural classification
Classifies objects together on the basis of the sum total of all their characters (features which exist in the group of objects in two or more distinguishable different states e.g. hair colour, eye colour in human)
It puts together those that are more alike in most respects
Classifies objects together on the basis of only one or a very few specially selected characters and ignores all the characters that the objects might have.
It does not take into account the natural relations of plants.
However, it is useful in horticulture. Plants can be classified on the basis of their ability to withstand drought e.g. drought tolerant, drought prone etc., which is useful information for crop husbandry.
