Potential of vermicompost produced from plant waste on the growth and nutrient status in vegetable production
Vermicompost contains plant nutrients including N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu and B, the uptake of which has a positive effect on plant nutrition, photosynthesis, the chlorophyll content of the…
Salinity induced changes in oxidative stress and antioxidant status as affected by applications of silicon in lettuce (Lactuca sativa).
Control of Biological Scum in Activated Sludge Plants by Means of Selective Flotation
By applying the process of selective flotation a quantitative method for the determination of biological scum has been developed and was used to compare the scum intensity of different activated sludge plants and to evaluate the efficiency of scum removal upon treatment.
Possible effects of regulating hydroponic water temperature on plant growth, accumulation of nutrients and other metabolites.
The possible benefits of regulating temperatures of the hydroponic solution with the aim of optimising production of flower in the glasshouse during winter periods are suggested.
Mycorrhizal root colonisation and the subsequent host plant response of soil less grown tomato plants in the presence and absence of the mycorrhizal stimulant, Mycotech
A hydroponic trial was carried out to assess the effect of inoculating tomato plants with AM fungi, in the presence and absence of a mycorrrhizal stimulant (Mycotech). Four treatments were applied:…
A Study of Oxygenation Techniques and the Chlorophyll Responses of Pelargonium tomentosum Grown in Deep Water Culture Hydroponics
Investigation of the viability of growing P. tomentosum in deep water culture (DWC) hydroponics and how best to aerate/oxygenate the nutrient solution to increase the chlorophyll content within leaves found the combination of high-frequency application of hydrogen peroxide, vortex oxygenation, and air-pump injection yielded the highest production of chlorophyLL.
Effects of different combinations of Hoagland's solution and Azolla filiculoides on growth and development of Beta vulgaris subsp. cycla 'Fordhook Giant' grown in hydroponic cultures
Although not as effective as the fully supplemented solutions, the Azolla plus Hoagland’s minus N solution can be modified in future to produce more nitrogen and in turn increase the growth rate of B. vulgaris.
Effects of various media compositions on the in vitro germination and discoloration of immature embryos of bird of paradise (Strelitzia reginae)
Results indicate the positive role of AC in reducing oxidative browning and the highest germination rate of embryos was observed in media containing AC without vitamin supplementation, while the highest level of media discoloration was seen in half-strength MS media without activated charcoal and vitamin supplementation.
A review: farmer's perceptions on endangered Proteaceae species of the Agulhas Plain, South Africa and the potential for their propagation.
The Agulhas Plain contributes largely to the commercial Protea cut flower industry in South Africa. The illegal field harvesting of Red Data species such as Leucadendron elimense subsp. elimense, L.…
Effects of antioxidants, plant growth regulators and wounding on phenolic compound excretion during micropropagation of Strelitzia reginae
The aim of this study was to determine the effects of antioxidant treatments, plant growth regulators (PGRs) and explants wounding in tissue culture involving Strelitzia reginae on total phenol…
