Learn the essential factors influencing plant growth and development. It begins by outlining the core requirements: air, light, water, and nutrients, delving into their specific components and effects on plant physiology. Air composition, light spectrum and intensity, water quality, and nutrient availability are discussed in detail. The lecture also covers the importance of the growing medium and spacing for optimal growth. It concludes with a Q&A session addressing topics like C3 and C4 photosynthesis and the selection of leaves for measurement using the LI-6800 photosynthesis system.
