FACTORS THAT INFLUENCE HYDROPONIC PHOTOSYNTHESIS OF BLEUBERRIES
Temperature
Optimum temperatures from 18-24 degrees Celsius
Influences the rate of photosynthesis, the collision of particles
Use of heaters, air conditioners and skylights can alter temperature of air.
Hydroponic solution
Substrates
Macro nutrients
Magnesium ions: used in synthesis of chlorphyll
Calcium ions
Sulfur ions
Phosphate: required for ATP synthesis
Nitrogen ions: required in chlorophyll
Micro nutrients
Iron
Manganese
Zinc
Aqueous solution required for photosynthesis
Different levels required for different stages of growth
Ventilation
CO2 conc.
optimal between 1200-1500ppm
Required as a reactant for photosynthesis and utilised in the Calvin cycle for light dependent reactions, crucial for plant growth.
Lighting
Intensity
12-16H per day required
Quallity (type of wave length)
Source
LED grow lights
Fluorescent lights
Distance from plants
Required for light dependent reactions of photosynthesis, photons absorbed by chlorophyll to supply energy to electron transport chains for ensuing reactions.
pH levels
Optimum levels between 4.5-5.5
Influences root health and nutrient availability essential for synthesis of chlorophyll required in photosynthesis
Can be easily altered with widely available chemicals
Oxygenation
Air stone
Required for aerobic respiration
