Study Notes

Introduction to Classification

A species is a group of plants with the same characteristics, genetically identical, and capable of interbreeding to produce viable offspring.
The species name is written as the genus name followed by the species name (e.g., Lycopersicon esculentum, the tomato).

Classification Hierarchy

Kingdom: the highest level of classification
Division: a grouping of classes with similar characteristics
Class: a grouping of related subclasses
Subclass: a grouping of related families
Family: a grouping of related genera
Genus: a grouping of related species
Species: the most specific level of classification
Examples of classification levels for tomato: Kingdom: Plantae, Division: Tracheophyta, Class: Angiospermae, Subclass: Dicotyledonea, Family: Solanaceae, Genus: Lycopersicon, Species: Lycopersicon esculentum

Importance of Classification

Classification is a useful tool in crop production, allowing for grouping of crops with similar characteristics
Classification can be done based on different criteria, depending on the reason for the classification

Botanical Classification

Botanical classification is based on the genetic makeup of plants, which is an important tool for studying plants
Related species often attract the same diseases and insects, and can act as a wintering host
Knowledge of botanical relationships is essential for working out a successful crop rotation system
The genetic makeup of a plant is called the genotype, and the morphological appearance is called the phenotype

Classification Based on Edible Parts

Vegetables can be grouped based on the edible parts of the plant, such as roots, underground stems, stems, petiole, leaves, fruits, and seeds
Cultivation similarities exist between crops with the same plant part as produce
Examples of classification based on edible parts include:
- Roots: beetroot, carrots, sweet potato, horseradish, parsnip, turnip, and radish
- Underground stems: potato, taro, onion, leek, and garlic
- Stem: asparagus and kohlrabi
- Petiole: rhubarb and celery
- Leaf: lettuce, spinach, cabbage, onion, mustard greens, cress, Brussels sprouts, kale, garlic chives, Swiss chard, chicory, parsley, and watercress
