Physiological maturity of seeds and colorimetry of fruits of Jatropha curcas L.

Physiological Changes in the Seeds of Jatropha curcas L. at Different Stages of Fruit Maturity

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 ...

The objective was to relate the coloration of fruits of Jatropha curcas L during the maturation process with morphometric (fruits and seeds) and germinative characteristics (seeds). Fruits were collected at various maturation stages from mast trees located in Eldorado/MS, and six maturation stages were visually classified based on fruit’s epicarp color. Epicarp digital colorimetry was used to c...

Physic nut, Jatropha curcas L

Pharmacognostic Studies on the Fruits of Jatropha Curcas Linn

Present paper deals with the pharmacognostic studies of the fruits of J. curcas Linn. The 75-80 cells thick pericarp is differentiated into epicarp, mesocarp and endocarp. Mesocarpic zone embeds non-articulated laticifers, tannin containing idioblasts and randomly distributed vascular bundles. Endocarp shows the occurrence of fibrous sclereids. Preliminary phytochemical screening of the drug po...

Global Analysis of Gene Expression Profiles in Developing Physic Nut (Jatropha curcas L.) Seeds

BACKGROUND Physic nut (Jatropha curcas L.) is an oilseed plant species with high potential utility as a biofuel. Furthermore, following recent sequencing of its genome and the availability of expressed sequence tag (EST) libraries, it is a valuable model plant for studying carbon assimilation in endosperms of oilseed plants. There have been several transcriptomic analyses of developing physic n...
