Abstract:   (31893 Views)
Aquaponics is one of the recirculating aquaculture systems in which plant grows without soil. Considering the lack of information about aquaponic culture for main crops like pepper and the absence of comparison of plant conditions in soilless culture, in this experiment eco-physiological characteristics of pepper in hydroponics and aquaponics were investigated. After starting the plants to flowering, eco-physiological parameters were measured using potable far-red gas analyzer LCA-4, ADC. The results showed that photosynthesis, stomatal conductance, transpiration, photosynthesis active radiation (PAR) and water use efficiency were higher in aquaponics compared to hydroponics, while, stomatal resistance and leaf surface temperature were higher in hydroponics. However, there was no significant difference in leaf surface temperature in hydroponics and aquaponics. It seems that due to better eco-physiological characteristics of pepper in aquaponics, its growth and development will be better in this system.
