A modified aeroponic system for growing small-seeded legumes and other plants to study root systems
Plant Methods
Background Various growth systems are available for studying plant root growth and plant–microbe interactions including hydroponics and aeroponics. Although some of these systems work well with Arabidopsis thaliana and smaller cereal model plants, they may not scale up as well for use with hundreds of plants at a time from a larger plant species. The aim of this study is to present step-by-step instructions for fabricating an aeroponic system, also called a “caisson,” that has been in use in several legume research labs studying the development of symbiotic nitrogen fixing nodules, but for which detailed directions are not currently available. The aeroponic system is reusable and is adaptable for many other types of investigations besides root nodulation. Results An aeroponic system that is affordable and reusable was adapted from a design invented by French engineer René Odorico. It consists of two main components: a modified trash can with a lid of holes and a commercially availab...
0 1 Getting to the roots of aeroponic indoor farming 2 3
2020
Vertical farming is a type of indoor agriculture where plants are cultivated in stacked systems. It forms a rapidly growing sector with new emerging technologies. Indoor farms often use soil-free techniques such as hydroponics and aeroponics. Aeroponics involves the application to roots of a nutrient aerosol, which can lead to greater plant productivity than hydroponic cultivation. Aeroponics is thought to resolve a variety of plant physiological constraints that occur within hydroponic systems. We synthesize existing studies of the physiology and development of crops cultivated under aeroponic conditions and identify key knowledge gaps. We identify future research areas to accelerate the sustainable intensification of vertical farming using aeroponic systems.

Aeroponics is a way of planting in which plants are suspended on the air and grow in a humid environment without soil. This technique has most advantages when compared to other planting techniques used in different parts of the world. With aeroponics one can control humidity, temperature, pH and water conductivity under a greenhouse. Since the roots are suspended on the air, it is possible to plant practically anywhere and cubic space can be used, and therefore, aeroponics can be applied in many different ways. The principles of aeroponics are based on the possibility of cultivating vegetables whose roots are not inserted in a substratum or soil, but in containers filled with flowing plant nutrition. In these containers' roots can find the best condition regarding oxygenation and moisture. These conditions allow for better plant nutrition assimilation in a more balanced way, with consequential faster development of the cultivated plants. The aeroponic system is more user-friendly as the plants are all separated, they are all suspended in the air and the roots of the plants are not in anything like soil or water. Also, the harvesting of crops is simple. Many vegetable crops like potato, yams, tomato, lettuce and some of the leafy vegetables are being commercially cultivated in aeroponic system.
The study of Lycopersicum esculentum rooting in aero-hydroponic system
Analele Universității din Oradea, Fascicula: Protecția Mediului, 2015
The base principle in an aero-hydroponic system is to grow the plants suspended into a closed or half-closed environment, by pulverizing the suspended roots with a mixture of water and water-soluble nutrients, while the aerial part develops on top. The study was performed between 9 th April-7 th May 2015 in the USAMV Cluj-Napoca's Greenhouse. For the experiment rooted tomato seeLSDings were used and three treatment variants were studied: V1-rooted tomato seeLSDings; V2-tomato seeLSDings with chopped roots and treated with gel; V3-tomato seeLSDings with chopped roots and not treated. After one week from the experiment's start, the tomato plants with chopped roots have formed new roots with lengths of 3.83 cm (V3) and 2.25 cm (V2). The root's length is greater for the chopped roots treated with gel compared to the ones not treated, data being statistically significant in favour of the treated variant.
. Aeroponics System of Cultivation in Horticultural Crops
Population of earth is expected to rise by 3 billion people. It is estimated that approximately 109 hectares of additional traditional land will be needed to feed them. Only 80% of the Earth's arable land is suitable for farming now. A greater quantity of hectares with optimum inputs is needed every day to feed the rising population. This chain of high priority problems requires an improvement in the management of the use of resources so that human consumption has the priority in its use. To solve the problems mentioned, new farming methods have been searched, one of them being aeroponics. With this technique, the plants are held by certain structures that are maintained in a way that the roots are sustained up in the air. Aeroponic literally means "growing in air." An aeroponic system is medium-less in that the roots of the plant are free hanging inside an open root-zone atmosphere. Aeroponics structure supplies optimum levels of water, nutrients and air to the growing chamber. Aeroponics is the process of growing plants in an air or mist environment without use of soil or an aggregate media. The word aeroponic is derived from the Latin word 'aero' (air) and 'ponic' means labour (work). This is an alternative method of soil-less culture in growth-controlled environments. The aeroponic culture technique is an optional device of soil-less culture in growth-controlled environments such as greenhouses. This method consists of enclosing the root system in a dark chamber and supplying a nutrient solution of mist device. This was widely used in horticultural species including potato, tomato, lettuce, cucumber and ornamental plants such as chrysanthemum. Aeroponic systems for seed production have been established following increased demand for more efficient high quality seed production
Aeroponics: A Polytropic Research Tool in the New Era of Agriculture
International Journal of Environment and Climate Change
Aeroponics is a technique of cultivating or culturing plants in the absence of soil or a consolidated medium. It is that the plant is just grown in the moist air or mist medium to transmit the nutrients required by plants. To be honest I call is as a tool for research and commercial production activities because when we talk about practical application there will be many aspects for consideration such as orientation, site selection, skilled technicians, economic costs weather, and climate mainly the traditional farmers. All these operations cannot be handled by a small and simple farmer with ease, this is the reason for the current trend of aeroponics which is new to people and being practically utilized only for research, aesthetics, and for commercial purposes. Aeroponics need special structures which can maintain a controlled environment for the fulfillment of all the basic and required conditions by the plants being studied or grown inside. It requires proper equipment like aero...
Aeroponics- A step towards sustainable farming
International Journal of Advance Research, Ideas and Innovations in Technology, 2018
Aeroponic is a type of vertical farming. It is actually a process which means the cultivation of plants without the use of soil or minimal use of soil. In this method, the roots of the plant are suspended in the air and nutrients are sprayed in the nutrient chamber. This process can be done in both ways whether be it a semi-closed environment or closed environment. The circumstance is controlled and it requires a lot of care with respect to temperature, humidity, pH etc. In recent years, the Aeroponic system has been used mostly to have a pesticides free cultivation. Prediction says that in coming years Aeroponic will increase the yield and also the quality of crops grown. The set up for Aeroponic includes a proper monitoring and control system for water and nutrients distribution for utilizing the Aeroponic cultivation at its best. The monitoring system monitors the chamber’s parameters such as temperature & humidity whereas control system manages actuators in delivering water and ...

New tools of microscopy, molecular biology, and genetics are making it possible for biologists to study roots with new vigour. Such investigations have enabled plant biologists to notice the symmetry, pattern, and simplicity of root structures so that there is now an exciting rebirth in the study of roots. The literature of root biology, development and structure is vast. In this short review we will concentrate on describing our notion of how roots are organized structurally, and then discuss what is known about tissue- and zone-specific gene expression in roots. Key words: Root apex, root anatomy, root development, gene expression. Root organization
Root Zone Respiration on Hydroponically Grown Wheat Plant Systems
2010
Root respiration IS a biological phenomenon that controls plant growth and physiological development during a plant's lifespan. This process is dependent on the availability of oxygen in the system where the plant is located. In hydroponic systems, where plants are submerged in a solution containing vital nutrients but no type of soil, the availability of oxygen arises from the dissolved oxygen concentration in the solution. This oxygen concentration is dependent on the , gas-liquid interface formed on the upper surface of the liquid, as given by Henry's Law, depending on pressure and temperature conditions. Respiration rates of the plants rise as biomass and root zone increase with age. The respiration rate of Apogee wheat plants (Triticum aestivum) was measured as a function of light intensity (catalytic for photosynthesis) and C02 concentration to determine their effect on respiration rates. To determine their effects on respiration rate and plant growth microbial communities were introduced into the system, by Innoculum. Surfactants were introduced, simulating graywater usage in space, as another factor to determine their effect on chemical oxygen demand of microbials and on respiration rates of the plants. It is expected to see small effects from changes in C02 concentration or light levels, and to see root respiration decrease in an exponential manner with plant age and microbial activity.
