Abstract Oviposition, development and survivorship of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) were evaluated on soybean and garden bean under laboratory conditions of 26.0 +/- 0.5 degrees C, 70 - 80% RH and a photoperiod of 14:10 (L:D). B. tabaci deposited more eggs and survivorship of nymphs was significantly greater in a choice-test on soybean, Glycine max L. (Merr.) (Fabeles: Fab...

Chromatographically distinct isoacceptors of leucyl-tRNA from mature bean leaves were all observed to hybridize with bean chloroplast and nuclear DNA in a ratio similar to that exhibited by the unfractionated leucyl-tRNA. Under the same hybridization conditions, maize tRNA failed to form a stable hybrid with bean DNA, and levels of hybridization between bean-leaf leucyl-tRNA and nuclear or chlo...

Legumes contain a variety of phytochemicals derived from the phenylpropanoid pathway that have important effects on human health as well as seed coat color, plant disease resistance and nodulation. However, the information about the genes involved in this important pathway is fragmentary in common bean (Phaseolus vulgaris L.). The objectives of this research were to isolate genes that function ...

1. The effects of various factors on rates of flow and composition of digesta leaving the abomasum of preruminant calves were studied. The possible relation of some of these effects to the development of serum antibodies to certain dietary constituents has also been examined. Two situations were distinguished: (a) unsensitized responses, shown by calves receiving milk protein or soya-bean produ...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

Let be a compactly suppported positive measure on the real line. A point x 2supp[ ] is said to be -regular, if, as n!1; sup deg(P ) n jP (x)j kPkL2(d ) !1=n ! 1: Otherwise it is a -irregular point. We show that for any such measure, the set of -irregular points in f 0 > 0g (with a suitable de…nition of this set) has Hausdor¤mh measure 0, for h (t) = log 1 t , any > 1. Orthogonal Polynomials on ...

Polyethylene mulch with a reflective silver stripe and a yellow summer squash, Cucurbita pepo L., trap crop were tested alone and in combination as tactics to reduce densities of Bemisia argentifolii Bellows & Perring eggs and nymphs, and incidence of bean golden mosaic geminivirus on snap bean, Phaseolus vulgaris L. Egg densities were consistently higher on squash than on bean, but egg densiti...

The soluble bean leaf auxin-binding protein (ABP) has a high affinity for a range of auxins including indole-3-acetic acid (IAA), alpha-napthaleneacetic acid, phenylacetic acid, 2,4,5-trichlorophenoxyacetic acid, and structurally related auxins. A large number of nonauxin compounds that are nevertheless structurally related to auxins do not displace IAA from bean ABP. Bean ABP has a high affini...

Liu G.D., Morgan K., Hogue B., Li Y.C., Sui D. (2015): Improving phosphorus use efficiency for snap bean production by optimizing application. Hort. Sci. (Prague), 42: 94–101. Phosphorus (P) is essential for crop production. Adequate application P rate is critical for enhancing productivity and profitability of snap bean (Phaseolus vulgaris L.). The goal of this study was to optimize P applicat...

The experiment was conducted in the cytogenetics laboratory of the Department of Genetics and Plant Breeding of Bangladesh Agricultural University during July 2008 to September 2009 aiming to analyze and compare the karyotypes of two genotypes of Lignosus bean (Dipogon lignosus L.) and Lablab bean (Lablab purpureus L.). Root tips from germinated seeds were collected, pretreated and fixed in ace...
