Phytotoxicity of methylene blue to rice seedlings
Methylene blue is widely used in various industrial branches. Due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. Hydroponic experiments were conducted with rice seedlings (Oryza sativa L. cv. XZX 45) exposed to methylene blue to determine the effective concentration using relative growth rate ...

Varietal differences in the growth of rice seedlings exposed to perchlorate and their antioxidative defense mechanisms
A hydroponic experiment was conducted to investigate the perchlorate (ClO4‐) phytotoxicity in different rice varieties. Considerable variations were observed when 24 rice varieties were treated with ClO4‐. The shoot height, root length and biomass of most varieties were significantly reduced by ClO4‐. The roots were more sensitive than the shoots. Hierarchical clustering analysis demonstrated ...

Antioxidant and prooxidant effects of lanthanum ions on Vicia faba L. seedlings under cadmium stress, suggesting ecological risk
The present study combined chemical analyses and biological measurements to investigate biphasic effects of La on Cd stress in leaves of Vicia faba seedlings, which were hydroponically cultivated for 15 d in the combination of 6 µM CdCl2 and 2 to 480 µM La(NO3)3, respectively. The results showed that contents of Cd first elevated above and then declined below the 6 µM single Cd treatment when 2 ...

Our Spacer: A Versatile Solution for Hydroponic Crops
In vegetable crops in particular, there are a number of tried and tested advantages to using our Spacers in hydroponic farming. They include providing a means of lifting the substrate away from the drainage stream whilst providing excellent aeration and avoiding a build-up of humidity below the substrate. These advantages have led to Spacers also being used with other applications and in ...

Lanthanum ions intervened in enzymatic production and elimination of reactive oxygen species in leaves of rice seedlings under cadmium stress
Rare earth elements (REEs) at proper concentrations were observed to alleviate heavy metal stress. However, the potential mechanisms are not clear. Thus, the present work focused on the mechanisms of lanthanum (La) ions on the generation and elimination of reactive oxygen species (ROS) production in leaves of rice seedlings hydroponically cultivated in 30 µM cadmium chloride (CdCl2) for two ...

Toxicity of sulfate and chloride to early life‐stages of wild rice (Zizania palustris)
Despite its importance in the great lakes region of north America, wild rice (Zizania palustris) sensitivity to sulfate is not well understood. A 21‐day hydroponic experiment was performed to determine the toxicity of sulfate to wild rice seeds and seedlings. Effects of six sulfate concentrations ranging from 10 to 5,000 mg/l and of chloride salts at equivalent conductivity were evaluated to ...

Field trial carried out in the ebro valley, Spain case study
Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

What is an Artesian Growing System?
The Artesian Growing System is a gravity-fed wicking system which supplies water to the base of a container from where it is wicked up to the plant. At the heart of the system is our Artesian Water Control Valve. This special float valve won’t release water until the water from its previous release has been taken up by the plant. In this way the plant is always assured of fresh oxygen-rich ...
