The present investigation aims to study the intraspecific diversity of thirteen faba bean genotypes (Vicia faba L. 2n=12) and to determine some selection criteria for plant breeding. Five yield parameters were studied: plant height (H), branch number per plant (BN/Pl), pod number per plant (PN/Pl), seed number per pod (SN/P) and yield per plant (Y/Pl). With a few exceptions, significant variabi...
The average opening rate of Vicia faba L. stomata was determined over an initial 20-minute light period following darkness. Nonsaturating intensities of broad band red and blue light had similar quantum effectiveness for the promotion of opening, whereas broad band green was about 40% and far red about 5% as effective. The opening rates under saturating red, green, and blue light were the same....
Faba bean gall (FBG) is a devastating disease of faba (Vicia faba) in Ethiopia. Studies were undertaken first to compare and contrast similarities between FBG symptoms morphology Ethiopia with those reported earlier China and, secondly, identify definitively the causal agent, previously considered as Olpidium viciae, through molecular studies. Morphological studies confirmed an epibiotic phase ...
The presence of chloroplasts in guard cells from leaf epidermis, coleoptile, flowers, and albino portions of variegated leaves was established by incident fluorescence microscopy, thus confirming the notion that guard cell chloroplasts are remarkably conserved. Room temperature emission spectra from a few chloroplasts in a single guard cell of Vicia faba showed one major peak at around 683 nano...
Using quantitative histochemical techniques, the carbohydrate levels of guard cells from open and closed stomatal apparatus of Vicia faba L. were compared. To minimize experimental error, all comparisons were between leaflets of the same pair. Stomata on one leaflet were caused to open by light and reduced CO(2). The other leaflet, which was in darkness, had closed stomata. In one experiment, d...
Reactive oxygen species (ROS) have been established to participate in stomatal closure induced by live microbes and microbe-associated molecular patterns (MAMPs). Chlorella as a beneficial microorganism can be expected to trigger stomatal closure via ROS production. Here, we reported that Chlorella induced stomatal closure in a dose-and time-dependent manner in epidermal peels of Vicia faba. Us...
The present study was carried out to evaluate the cytotoxic effects of refinery wastewater collected from different stations of the Kizilirmak river on Vicia faba L. root tip cells. For this aim, we used the germination percentage, root length, weight gain and micronucleus (MN) frequency as indicators of cytotoxicity. Additionally to the cytological analysis, DNA analyses were performed in root...
To investigate genetic diversity and relationships of 101 faba bean (Vicia faba L.), landraces and varieties from different provinces of China and abroad were analyzed by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE). A total of 2625 unambiguous and stable bands from 101 germplasms were detected, and 36 different bands were classified according to the electrophoretic mo...
Parasitoid host selection behaviour has been extensively studied in experimentally simplified tritrophic systems formed by one single food chain (one plant, one herbivore and one parasitoid species). The "Mother knows best" hypothesis predicts that the preference for a plant-host complex should be positively correlated with plant quality for offspring performance. We studied the host selection ...
Legumes are an alternative to animal foods due their high protein content. Like other legumes, Vicia faba (faba bean) has However, bean breeding with classical methods is challenging inbreeding depression, self-incompatibility, and abortive embryo formation. The inadequacy of the problems in fertilization biology plant limits production new varieties. Therefore, importance using vitro haploidiz...
