Study Notes
Root and Tuber Crops
- Root crops are grown for their edible roots (carrots, beets, turnips)
- Tuber crops are grown for their thickened underground stems or tubers (potatoes, cassava, yam)
- Staple crops like potatoes and cassava provide essential calories and nutrients
- Vegetables like carrots and beets are important for balanced diets
- Sweet potatoes are valued for their health benefits
- Root and tuber crops are rich in vitamins, carbohydrates, and essential nutrients, crucial for human health
- They are vital for food security, especially during lean seasons
- These crops contribute significantly to local economies and livelihoods
- Root and tuber crops are also used as animal feed and in industrial processes
- Traditional farming practices limit crop yields
- Root and tuber crops are vulnerable to pests and diseases, impacting production
Coffee, Tea, and Spices in Ethiopia
- Coffee originated in Ethiopia, evolving into a global commodity
- Tea, initially from China, has adapted to diverse climates like Ethiopia's
- Spices like cinnamon, pepper, and cloves have been crucial for trade
- Brazil, Colombia, and Ethiopia are major coffee producers, with tea production significant in India and China
- Ethiopia exports coffee and other crops, contributing to foreign exchange and local economies
- Coffee cultivation thrives in specific conditions (altitude, rainfall, shaded areas)
- Coffee post-harvest involves drying, washing, and roasting for flavor development
- Tea involves careful picking of young leaves and buds, with processing methods affecting final quality
- Spice cultivation requires specific environmental conditions (e.g., turmeric needs warmth, black pepper needs support)
Plant Tissue Culture and Genetic Engineering
-
Plant tissue culture is a technique for growing plant cells, tissues, or organs in an artificial environment
-
Micropropagation involves producing clones of a plant from a small piece of the parent plant
-
Ornamental plants, commercial plants, agricultural, and horticultural plants are examples of plants propagated with tissue culture
-
Tissue culture enables rapid reproduction of uniform plants, seedless propagation, and safer transport
-
Genetic modification alters plant genes to enhance traits (pest resistance, higher yields, nutritional quality)
-
Traditional breeding only involves species with close relationships
-
Genetic engineering transcends species barriers
-
Genetic engineering benefits include herbicide resistance, pest and disease resistance, and nutritional improvement.
