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
