Area Of Science
- Horticultural science
- Sustainable agriculture
- Plant physiology
Background
- Lemon basil (Ocimum × citriodorum) is a valuable aromatic herb.
- Traditional cultivation relies on substrates like rock wool, posing environmental concerns.
- There is a need for sustainable alternatives in intensive herb production.
Purpose Of The Study
- To evaluate sustainable substrates for lemon basil production.
- To compare aquaponic and hydroponic cultivation systems.
- To assess the impact of substrate composition and cultivation system on plant growth and quality.
Main Methods
- Experiment 1: Compared coconut fiber-perlite mixtures with rock wool for germination and early growth.
- Experiment 2: Assessed plant performance in a decoupled aquaponic system versus hydroponics using optimal substrate (70% coconut fiber:30% perlite).
- Analyzed seed germination, leaf number, leaf area, mineral uptake, and flavonoid content.
Main Results
- A substrate of 70% coconut fiber and 30% perlite (F70:P30) significantly improved germination and seedling growth.
- Decoupled aquaponics increased flavonoid content by 52.5% and enhanced calcium and magnesium uptake compared to hydroponics.
- Aquaponics yielded comparable results to hydroponics while improving nutritional and phytochemical quality.
Conclusions
- Coconut fiber-perlite mixtures offer a sustainable alternative to rock wool, reducing environmental impact.
- Aquaponic cultivation is a viable strategy for sustainable lemon basil production, enhancing plant quality.
- Findings support the adoption of eco-friendly substrates and cultivation practices for intensive vegetable production.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
Plant cells maintain appropriate osmotic balance in extreme conditions. For instance, plants in dry environments store water in vacuoles, limit the opening of their stoma, and have thick, waxy cuticles to prevent unnecessary water loss. Some species of plants that live in salty environments store salt in their roots. As a result, water osmosis occurs in the root from the surrounding soil.
