Affinity Distance Values among Somatic Metaphase Chromosomes

In maize root-tip metaphase preparations, all distances between two chromosomes were measured in 50 cells from each of seven stocks and in 30 from one stock; four were arrested with cold, two with 8-hydroxyquinoline, one with colchicine and one with monobromonaphthalene Standardized, affinity-distance values were calculated for all pairs of homologues and pairs of nonhomologues from each prepar...

A Comparison of Staining Techniques for Somatic Chromosomes of Strawberry

A factorial combination of pretreatments, fixatives, and stains was examined to identify the best available method for staining the chromosomes of strawberry (Fragaria × ananassa Duch. ‘Chandler’) root-tip cells. Three pretreatments ( a -bromonaphthalene, p -dichlorobenzene, and 8-hydroxyquinoline), three fixatives (Farmer’s fluid, Carnoy’s fluid, and Newcomer’s fluid), and five stains (acetoca...

Effect of NOx on the somatic chromosomes of goldsmiths.

The genotoxic effect of NOx was investigated on somatic human chromosomes obtained from lymphocytes of 45 goldsmiths exposed to 1770.5 mg/m3 NOx in ambient air at normal temperature and pressure and compared to an equal number of matched controls breathing air containing 50 microgram/m3 NOx. Short-term lymphocyte cultures were set up from blood collected from both exposed and control individual...

Identification of Chrysanthemum (Chrysanthemum morifolium) Self-Incompatibility

There has been a heated argument over self-incompatibilityof chrysanthemum (Chrysanthemum morifolium) among chrysanthemum breeders. In order to solve the argument, we investigated pistil receptivity, seed set, and compatible index of 24 chrysanthemum cultivars. It was found that the 24 cultivars averagely had 3.7-36.3 pollen grains germinating on stigmas at 24 hours after self-pollination throu...
