Crude protein extracts from the chickpea (Cicer arietinum L .) pathogenic fungus Ascochyta rabiei catalyze the N A D PH dependent conversion of the pterocarpan phytoalexins medicarpin and maackiain to 1) 2'-hydroxyisoflavans, 2) 1 a-hydroxypterocarp-l,4-diene-3-one, and 3) 10,2'dihydroxyisoflav-8-ene-7-one derivatives. A pterocarpan: N A D PH oxidoreductase which cleaves the benzylphenyl ether ...

This paper shows the changes of the volatile compounds from four Astragalus species at three phenological stages: leaf development, flowering and fructification, which might be connected with the plant defense. After GC/MS analyses of Astragalus glycyphyllos L., A. hamosus L., A. cicer L. and A. spruneri Boiss., different groups of volatile compounds were found: hydrocarbons, alcohols, aldehyde...

Conservationists often propagate rare species to improve their long-term population viability. However, seed dormancy can make propagation efforts challenging by substantially lowering seed germination. Here I statistically compare several pretreatment options for seeds of Astragalus cicer L.: unscarified controls and scarification via physical damage, hot water, acid, and hydrogen peroxide. Al...

The effective federal funds rate is determined in a competitive interbank market, while the target federal funds rate represents a policy variable. This paper proposes a theory of the determination of the effective funds rate. According to the main result, the latter is a Lagrange multiplier that vanishes if excess reserves emerge. This is exactly what happened in the United States in September...

We compared root responses of the Ni-hyperaccumulator plant Berkheya coddii Rossler with the non-accumulator plant Cicer arietinum L. to Ni heterogeneity in soil. We grew plants in growth containers filled with control soil, homogeneously spiked, and heterogeneously spiked soil with Ni concentrations of 62 and 125 mg kg(-1). Neutron radiography (NR) was used to observe the root distribution and...

This research was made during the 2011 and 2012 growing periods in the trial filed of "Research Station for Management of Soil Water and Desertification" according to “Randomized Blocks Design” with 3 replications. Research material was the following chickpea genotype; CA119, CA128, CA149, CA150, CA222, CA250, CA254 and other 2 commercial varieties named as Gökçe and Yaşa. Some agronomical char...

Flowering time is an important trait for adaptation and productivity of chickpea in the arid and the semi-arid environments. This study was conducted for molecular mapping of genes/quantitative trait loci (QTLs) controlling flowering time in chickpea using F2 populations derived from four crosses (ICCV 96029 × CDC Frontier, ICC 5810 × CDC Frontier, BGD 132 × CDC Frontier and ICC 16641 × CDC Fro...
