Matthiola incana (Brassicaceae) is an important ornamental plant, which is used as cut flower, pot plant, and landscape. Traditionally, it is propagated via seeds, but interest is given in vegetative propagation of parental lines as well as superior single plants. Micropropagation by organogenesis is an efficient in vitro propagation method for Matthiola incana. Starting from seeds, apical bud ...

The cactus Mammillaria gracillis Pfeiff. was propagated in vitro on Murashige and Skoog (MS) medium without any growth regulators. At the bases of some plants abundant callus masses developed. Lower agar and higher MS salt concentrations stimulated callus pro­ duction. In the culture, morphologically normal and hyperhydric shoots were regenerated. The growth of crown-gall tumour was induced on ...

Greenhouse and field microplot studies were conducted to compare soybean shoot and root growth responses to root penetration by Heterodera glycines (Hg) and Meloidogyne incognita (Mi) individually and in combination. Soybean cultivars Centennial (resistant to Hg and Mi), Braxton (resistant to Mi, susceptible to Hg), and Coker 237 (susceptible to Hg and Mi) were selected for study. In the greenh...

This paper presents the mesh selectivity of a net pot for white-spotted conger eel Conger myriaster. A cover-net fishing experiment was carried out in October 1995 and 1996, using five mesh openings; 11.6, 13.6, 15.5, 18.1, and 21.0 mm with a cover-net of 10.8 mm mesh opening. Each mesh-size net pot had a slightly different mesh selectivity curve in terms of R(=G/P), girth ratio G to mesh perim...

The interactions of Heterodera glycines at four egg inoculum levels (0, 100, 1,000, and 10,000 per pot) and three cyst levels (0, 100, and 200 per pot) and Calonectria crotalariae at 500, 5,000, and 50,000 microsclerotia per pot were evaluated on soybean. At the two lowest nematode egg levels, the presence of C. crotalariae did not affect nematode reproduction. At 10,000 eggs per pot, however, ...

OBJECTIVE Characterisation of anticoagulant control is fundamental to investigations of its association with clinical outcome. Anticoagulant control depends on several factors. This paper aims to illustrate the implications of different methods for measuring and analysing anticoagulant control in patients with second generation mechanical heart valve prostheses. METHODS International normalis...

Microbially-unsafe water is still a major concern in most developing countries. Although many water-purification methods exist, these are expensive and beyond the reach of many people, especially in rural areas. Ayurveda recommends the use of copper for storing drinking-water. Therefore, the objective of this study was to evaluate the effect of copper pot on microbially-contaminated drinking-wa...

Pot-shaped fluorescent aggregates of 6,6-dicyanopentafulvene derivative serve as reactors and stabilizers for the preparation of luminescent ZnO nanoparticles, which exhibit high catalytic efficiency in one-pot multicomponent synthesis of tetrahydropyridines.

A tandem electrosynthesis of homoallylic alcohols from alcohols in one-pot was realized. In virtue of this one-pot electrosynthesis, the traditional reaction substrates of allylation were broadened from carbonyl compounds to alcohols.
