The objective of present study was to determine appropriate fruit harvesting stage for Jatropha curcas L. for getting seeds with good oil content and better germination. The seeds separated from the fruits harvested at yellow capsule stage (C2) showed maximum germination efficiency, both under laboratory and nursery conditions whereas seeds separated from the fruits harvested at brownish black ...

Longicorn beetle, Acanthophorus rugiceps Gahan (Coleoptera: Cerambycidae), is reported for the first time as a confirmed host on physic nut, Jatropha curcas L. (Malpighiales: Euphorbiaceae), from India, causing extensive damage to roots. Plants of three years age and above were prone to attack by this pest. In a six year study beginning in 2005, about 11.3 percent of plants in a 16.25 acre phys...

Developing a protocol for somatic embryogenesis (SE) adult mother plants of Jatropha curcas, aids to overcome problems such as harvesting time and an uneven yield, providing the opportunity propagate proven elite genotypes. Until now, several authors have achieved SE in J. curcas using different explants, however, none these protocols been used plant material. Furthermore, challenge overcoming ...

The objective of this research is to produce the low-cost activated carbon from Jatropha curcas L. by chemical activation using zinc chloride ZnCl2. The effects of the impregnation ratio on the surface and chemical properties of activated carbon were investigated. The impregnation ratio was selected at the range of 1:1-10:1 for investigation. The optimum conditions resulted in an activated carb...

Thrombosis is one of the leading cause of thromboembolic disorders affecting million persons worldwide. Several plants used for the treatment of thromboembolic diseases in different systems of traditional medicine have shown anticoagulant/antithrombotic activity and such plants claimed in the traditional system still remain to be scientifically investigated. The review explored various herbal d...

Jatropha curcas is a woody-shrub species of the Euphorbiaceae family that widely distributed in tropical and subtropical areas. The great interest its cultivation lies potential for achieving elevated yields high-quality oil. Another characteristic makes J. promising ability to produce green energy even high-salinity soils. For commercial be considered effectively competent withstand these cond...

Jatropha curcas L. (Euphorbiaceae) is a plant species widely present in tropical and subtropical regions that have been studied mainly for its potential biofuel production; it also known toxic substances. To explore use as an insecticide, we the effect of seed extract from green fruit oils mature dried J. on aphid Myzus persicae (Hemiptera: Aphididae). Seven concentrations extracts different ma...

Jatropha curcas L. is an important biofuel plant with excellent tolerance of barren environments. However, studies on the regulatory mechanisms that operate in this plant in response to nitrogen (N) shortage are scarce. In this study, genome-wide transcriptional profiles of the roots and leaves of 8-week old physic nut seedlings were analyzed after 2 and 16 days of N starvation. Enrichment resu...

The effects of increasing NaCl concentrations on biomass, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and phenylalanine ammonia-lyase (PAL) in Jatropha curcas L. seedlings were investigated. The fresh weights of cotyledons and radicles with increasing NaCl concentrations decreased progressively, and the fresh weight of hypocotyls reached the lowest level at NaCl concentration ...

Plant poisoning is not an uncommon problem in Sri Lanka. A hospital based prospective study showed that Jatropha curcas, Ricinus communis, Dieffenbachia, Adenia palmata, Amanita phalloides and Thevetia peruviana are common poisonous plants implicated in poisoning among children in Sri Lanka. [1]. In the past, deliberate ingestion of yellow oleander seeds (Thevetia peruviana) was a common method...
