Genetic diversity among 20 sesame (Sesamum indicum L.) accessions was examined at DNA level by means of random amplified polymorphic DNA (RAPD) analysis. Ten primers used produced a total of 93 RAPD fragments, of which 70 (75%) were polymorphic. Each primer generated 5 to 17 amplified fragments with an average of 9.3 bands per primer. Based on pair-wise comparisons of RAPD amplification product...

In a 1987 field study juveniles of Meloidogyne arenaria assayed at the time of peanut harvest were almost undetectable in plots planted with American jointvetch (Aeschynomene americana), castor bean (Ricinus communis), partridge pea (Cassia fasiculata), sesame (Sesamum indicum), and cotton (Gossypium hirsutum), whereas plots with peanut (Arachis hypogaea) averaged 120 juveniles/100 cm(3) soil. ...

Three iridoids (lamalbid (I1), sesamoside (I2) and shanzhiside methyl ester (I3)) and seven polyphenols (cistanoside F (P1), chlorogenic acid (P2), pedalitin-6-O-laminaribioside (P3), pedaliin (P4), isoacteoside (P6), pedalitin (P7) and martynoside (P8)) were identified in young sesame leaves (Sesamum indicum L.) other than the acteoside (P5) reported previously. P3 was a new compound, and I1, ...

Salinization is a global environmental problem. It particularly prevalent in Africa areas with low rainfall trend such as the Senegalese groundnut basin where 20% of land affected. reduces food production by more than 10%. In Senegal, sesame (Sesamum indicum L.) moderately tolerant to drought and salinity increasingly cultivated. an alternative fight poverty rural allows revaluation salty land....

Gamma tocopherol content of 7 Iranian sesame seeds (sesamum indicum L.) was determined by high performance liquid chromatography using C8 column and methanol, water and butanol as mobile phase. The gamma-tocopherol content varied from 563 to 1095 mg/kg in oil and 293 to 569 mg/kg in sesame seed and was in broad agreement with the Codex range. A large variation was found in the concentration of ...

this study was performed in order to evaluate the effects of spraying micronutrients iron, zinc, calcium on yield and yield components of seven sesame varieties on 2007 cropping season in research farm of shahed university. the experiment was performed as split-plot based on randomized complete blocks design with three replications. the main factor included feso4, znso4, cano3 and control (wate...

Major lignans of sesame sesamin and sesamolin are benzodioxol--substituted furofurans. Sesamol, sesaminol, its epimers, episesamin transformation products found in processed products. Synthetic routes to all known but only sesamol is synthesized industrially. Biosynthesis furofuran begins with the dimerization coniferyl alcohol, followed by formation dioxoles, oxidation, glycosylation. Most gen...
