“…The ethyl acetate fraction after fractionation showed the highest activity of 68% parasite elimination at the end of the incubationas as compared to chloroform extract which had antimalarial activity of 61% . Traditional uses of Dendrathema indicum extracts particularly in the treatment of of fever , eye ailments, gonorrhoea ,deep rooted boils, inflammation of the throat eyes and cervix, eczema itchiness of the skin are common (Carvalho, 2005).These can be justified by the presence of various secondary metabolites revealed by the phytochemical analysis The results of the phytochemical analysis (Table 1) prominently indicate the presence of carbohydrate, glycosides, saponins, tannis, flavanoids, resins and sterols. The search of new compounds from plants is of course an important area of research for exploring new potential drugs for malaria.…”

Malaria being a major health problem, demands for search for alternative anti-malaria drugs. Dendrathema indicum/ Dunkufea plant used in the treatment of malaria in the northern part of Nigeria was evaluated for activity against Plasmodium falciparum. The crude ethanol extract of the plant, n-hexane, chloroform and ethyl acetate and last residue fractions obtained by maceration of the crude ethanol extract were screened for activity against Plasmodium falciparum, the last residue and hexane fraction did not inhibit significantly even at a concentration of 200µg/ml, the ethyl acetate fraction obtained after maceration was the most active fraction. From the result of the photochemical analysis all the common classes of secondary metabolites tested were present in the plant except alkaloid.

“…Using different plant densities in combination with different temperatures (Carvalho et al, 2005;Ploeg, 2007) at different crop stages, a possibility of the mobile cultivation systems, arises a lot of opportunities to enhance production per m 2 and increase energy efficiency of greenhouse chrysanthemum cultivation. We show here till day 14, very high plant densities (344 plants m -2 ) are feasible, with a small cost (9%) in 919 TDM s , but with a big advantage in production per m 2 (180%).…”

Three levels of irrigation frequencies, provided by root misting, combined with three plant densities and two spacing treatments were tested to evaluate the optimum conditions during the first crop stages of chrysanthemum in a soilless cultivation system (aeroponics) in an experiment conducted in autumn. The optimum misting frequency was 32' times  min h -1 . A higher frequency (121') had no additional effect, whereas the lowest frequency (16') had a negative effect on total shoot dry mass (TDM s ) are feasible until week 2 with hardly any negative effects on plant growth, while spacing schemes give several possibilities for a smaller reduction of the TDM s , than that expected by the higher initial densities.

A virtual plant that responds to the environment like a real one: the case for chrysanthemum

et al. 2012

Summary• Plants respond to environmental change through alterations in organ size, number and biomass. However, different phenotypes are rarely integrated in a single model, and the prediction of plant responses to environmental conditions is challenging. The aim of this study was to simulate and predict plant phenotypic plasticity in development and growth using an organ-level functional-structural plant model, GreenLab.• Chrysanthemum plants were grown in climate chambers in 16 different environmental regimes: four different temperatures (15, 18, 21 and 24°C) combined with four different light intensities (40%, 51%, 65% and 100%, where 100% is 340 lmol m )2 s )1 ). Measurements included plant height, flower number and major organ dry mass (main and side-shoot stems, main and side-shoot leaves and flowers). To describe the basipetal flowering sequence, a position-dependent growth delay function was introduced into the model.• The model was calibrated on eight treatments. It was capable of simulating multiple plant phenotypes (flower number, organ biomass, plant height) with visual output. Furthermore, it predicted well the phenotypes of the other eight treatments (validation) through parameter interpolation.• This model could potentially serve to bridge models of different scales, and to link energy input to crop output in glasshouses.
