Nodule CO2 fixation via PEPC provides malate for bacteroids and oxaloacetate for N assimilation. The process is therefore of central importance for efficient nitrogen fixation. Nodule CO2 fixation is known to depend on external CO2 concentration. The hypothesis of the present paper was that nitrogen fixation in alfalfa plants is enhanced when the nodules are exposed to elevated CO2 concentratio...

Strawberry is a perennial fruit crop of high importance in the market. It highly recommended both as table and processed due its nutrient content. The growth period strawberry short hence doesn’t require much time for development. Aeroponic on other hand seems to provide better cultivation annual species controlled conditions meticulous way. A field experiment was conducted at Horticulture Rese...

Accurate detection of cutting diseases in the process aeroponic rapid propagation is very important for improving rooting rate and survival cuttings. This paper proposes to use image processing, with a dataset growth mulberry cuttings backward (BP) neural network, identify mildew on roots branches propagation, before extracting texture color features. An intelligent control aeroponics system wa...

Aeroponics is a technique of cultivating or culturing plants in the absence soil consolidated medium. It that plant just grown moist air mist medium to transmit nutrients required by plants. To be honest I call as tool for research and commercial production activities because when we talk about practical application there will many aspects consideration such orientation, site selection, skilled...

Plant propagation via in vitro culture is a very laborious and time-consuming process. The growth cycle of some of the crop species is slow even in the field and the consistent commercial production is hard to maintain. Enhanced methods of reduced cost, materials and labor significantly impact the research and commercial production of field crops. In our studies, stem-segment explants of Brassi...

A pressure chamber and a root pressure probe technique have been used to measure hydraulic conductivities of rice roots (root Lp(r) per m(2) of root surface area). Young plants of two rice (Oryza sativa L.) varieties (an upland variety, cv. Azucena and a lowland variety, cv. IR64) were grown for 31-40 d in 12 h days with 500 micromol m(-2) s(-1) PAR and day/night temperatures of 27 degrees C an...

this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...
