According to the Langmuir model, the maximum adsorption capacities for the bark, endosperm and endosperm + seed coat of Jatropha were, respectively, for Cu2+ 11.541, 20.475 and 22.910 mg g-1, and for Zn2+ 14.852; 15.888 and 14.674 mg g-1, with the predominance of chemisorption in monolayer. The choice of Jatropha curcas was due to its high non-edible seed oil production, fast-growing nature and the low-input requirements for its cultivation (Henning, 2004; Chauhan et al., 2012).
It is so drought-tolerant that it can even be grown in desert environments, and it will tolerate poor soils, making it a great crop for areas that would not typically be valuable as farmland. The seed typically contains 35 percent oil which has properties highly suited to making . Another aim is to determine the gross caloriﬁ c value of these components and compare the values with the gross caloriﬁ c values of pressed oil.
Sunscreen preparations derived from ethyl acetate fractions of Jatropha leaves are made. is a plant resistant to drought, versatile with many attributes and considerable potentials. The unisexual flowers are produced on the same inflorescence, with the ratio of male flowers to female flowers ranging from 10:1 to 30:1. Somatic embryo can produce a large number of embryos and obtain a large number of plants all year round. One of the alternative energy currently being developed is biofuel, including biodiesel. In the present study the effectiveness of Jatropha curcas oil on inactivation of some mycoflora were determined. press-cake and inorganic NP fertilizers on the productivity of potato (Solanum tuberosum L.) and soil properties.
of Jatropha curcas and Rubber seed oils as sources of viable renewable substitute for petroleum diesel. Experiments were performed varying the pressure (13 and 20 MPa) and the temperature (50°C and 60°C). Jatropha (Jatropha curcas L.) is one of the important crop for biofuel industry development and have the nature of drought tolerance that can be cultivated in marginal areas.
Jatropha curcas is a wild growing hardy plant well adapted to acid and moisture demand and can come up stony, gravelly or sallo and even calcareous soils. As a measure of testing the antimicrobial property of Jatropha curcas oil were subjected against six selected fungi viz. Jatropha curcas seeds in terms of weight ratio of the subcomponents, as a seed coat, seed kernel. alternative energy feed stocks, Jatropha curcas has been chosen, alongside other oil producing crops. The oil from Jatropha curcas seeds can be converted into biodiesel, but is it the solution to our energy problem? The biomass wastes are leaf and stem from pruning, fruit hull, seed husk, and oily-cake. The reasons being included properties like it is highly biodegradable, non-toxic and has almost zero emissions.
This succulent plant is highly resistant to drought.
Recent research revealed that TERMINAL FLOWER 1 (TFL1) homologues are involved in the critical developmental process of floral initiation in several plant species. The plant is used to produce the non-edible Jatropha oil, for making candles and soap, and as a feedstock for the production of biodiesel.
Jatropha curcas L seeds are essential to improve the design of equipment for harvesting, processing and storage of the seeds. This study was conducted to investigate physical, mechanical and chemical properties of Jatropha curcas seed and kernels. Easy to establish, jatropha has a speedy growth curve, & produces seeds for well over for 50 years. The name Jatropha curcas was first used by Linnaeus, and although there are a number of synonyms this name is still valid today. guajava has the potential to minimize microbial populations in a cut flower preservative solution and extend the vase life of the flower. Introduction The uncertainty of long-term fossil fuel supplies, volatile fuel prices and increasing CO2 emissions have generated much interest in alternative fuel sources, especially ‘biofuels’, which are defined as solid, liquid or gaseous fuels obtained from biological material. We aimed to propose a reliable and accurate model using non-destructive measurements of leaf length (L) and/or width (W) for estimating leaf area (LA) of three genotypes of purging nut (Jatropha curcas L.), i.e. In the context of energy security, rural development and climate change, India actively promotes the cultivation of Jatropha curcas , a biodiesel feedstock which has been identified as suitable for achieving the Indian target of 20% biofuel blending by 2017.
One of cultivation technology that determines the success of planting jatropha seedlings in the field is the provision of plant nurseries in general use media that is around, such as soil and organic fertilizer. This species has been asso-ciated almost exclusively with oil production because its seeds contain phorbol esters, which are toxic to humans and many animals (Heller 1996). Summary: Jatropha curcas is a herbal preparation used in the tropics for the treatment of threatened abortion and related problems associated with pregnancy.
The vegetable oil was used without a pretreatment.
oilseed plant, in this study, native populations from Chiapas, Mexico, were evaluated, using microsatellite DNA markers. Jatropha curcas Linn is one of the plants that have potential substants to protect skin from the adverse effects of UV rays.
The characteristics assessed include oil yield, specific gravity, density, acid value, free fatty acid, iodine value, saponification value, peroxide value, viscosity and flash point. Results suggested that increased copper concentrations lead to decreased shoot elongation and seedling biomass. Interest in Jatropha curcas as a source of oil for producing biodiesel has arisen as a consequence of its perceived ability to grow in semi-arid regions with low nutrient requirements and little care.
