Interspecific facilitation on phosphorus uptake was observed in faba bean/maize intercropping systems in previous studies. The mechanism behind this, however, remained unknown. Under nitrate supply, the difference in rhizosphere acidification potential was studied by directly measuring pH of the solution and by visualizing and quantifying proton efflux of roots between faba bean (Vicia faba L. ...

Subcellular localization of the starch-degrading enzymes in Vicia faba leaves was achieved by an electrophoretic transfer method through a starch-containing gel (SCC) and enzyme activity measurements. Total amylolytic and phosphorolytic activities were found predominantly in the extrachloroplastic fraction, whereas the debranching enzymes showed homogenous distribution between stromal and extra...

Until now, neither phenotypic nor molecular approaches have been used to characterize the landraces of Palestine faba beans (Vicia faba). We used PCR-based RAPD markers to determine the genetic diversity and relatedness among 26 Palestinian faba bean landraces (traditional farmers' varieties) from 8 localities in the West Bank, Palestine. In tests with 37 primers, 14 generated no polymorphic ba...

The effect of low pH on net H(+) release and root growth of corn (Zea mays L.) and broad bean (Vicia faba L.) seedlings was investigated in short-term experiments at constant pH. Broad bean was more sensitive to low pH than corn: the critical values (pH values below which net H(+) release and root growth ceased) were pH 4.00 (broad bean) and pH 3.50 (corn) at 1 millimolar Ca(2+). Both proton re...

Wilson and McNab' reported an increase in live-weight and a reduction in pancreas size of chicks when field beans (Viciu fabu L.) were autoclaved at 120 "C for 30 min. Such effects may be due to the presence in the raw field bean of a trypsin inhibitor analogous to those found in the soyabean and other legumes. Information on the presence of trypsin inhibitors in the field bean and on growth of...

Pot-test experiments were conducted to study the influences of mulching and fertilizing on the migration of heavy metals from soil to Vicia faba (broad bean). Semi-transparent film was used to mulch soil. Swine manure compost was mixed with soil at a rate of 50 mg kg(-1) to fertilize the soil. Broad bean was grown for several months until fruits were formed. Soils and bean parts were sampled to...

Broad bean (Vicia faba) is a herbaceous climbing plant that can self-pollinate and grow in any type of soil. It is now cultivated throughout the world and commonly used in cooking. Vicia faba belongs to the Fabaceae family and comprises 3 distinct varieties: Vicia faba var minor, Vicia faba var equina, and Vicia faba var major, which is the most widely eaten. Broad beans are eaten raw, cooked, ...

Polyphenoloxidase was purified from broad bean (Vicia faba) leaves. The purified enzyme contained two immunocross-reactive proteins of approximately 60 to 65 and 43 to 45 kilodaltons. Further electrophoretic separation resolved these proteins into doublets with molecular mass of 61.5, 60, 44.5, and 43 kilodaltons, respectively. Each of the four polypeptides was transferred to Immobilon and subj...

Faba bean plants (Vicia faba) showed remarkable resistant to wilt disease caused by Fusarium solani pv. Phaseoli when watered with a mixture of heavy metal at a concentration 10mg/L. However the use of Zn, Pb alone slightly increases the susceptibility of bean plants to Fusarium wilt. Plants exposed to Cd or Cu treatment accelerate the symptoms appearance in infected plant. The toxicity of a si...
