Horticulture: Branches and Environmental Factors

Section role: This presentation supports 'The Four Pillars of Horticulture' section while the teacher explains the specialized branches and the key environmental factors influencing plant growth. Slides: (1) Title Slide: 'Horticulture: The Four Pillars'; (2) Introduction to Horticultural Branches: bullets: Horticulture definition (revisiting from Section 1), overview of specialization, why biological requirements are universal; (3) Floriculture and Olericulture: bullets: defining Floriculture (flowers), specific examples like roses and orchids, defining Olericulture (vegetables), specific examples like lettuce and tomatoes; (4) Pomology and Landscape Horticulture: bullets: defining Pomology (fruits and nuts), specific examples like apples and almonds, defining Landscape Horticulture (design, installation, maintenance), examples like parks and gardens; (5) Environmental Factors: The 'Big Four': bullets: overview of critical environmental variables for plant success, introducing Light, Water, Temperature, Growing Media; (6) Light: Intensity and Photoperiod: bullets: explanation of light intensity, explanation of photoperiod, prompt for discussion: 'Why is photoperiod critical for commercial greenhouse growers?'; (7) Water: Turgor Pressure: bullets: importance of water for plant life, definition and role of turgor pressure; (8) Temperature: Hardiness Zones: bullets: influence of temperature on plant growth, concept of hardiness zones for plant selection; (9) Growing Media: pH and Porosity: bullets: going beyond 'dirt' to discuss soil components, explanation of humus and soil structure, impact of pH and porosity on nutrient availability and root health; (10) Horticulturist's Role: bullets: manipulating environmental variables, maximizing yield and aesthetic quality; Closing slide: 'How do horticulturists balance the needs of specific plants with universal biological requirements?' — setting up problem-solving discussions in Section 3.
