The cytological effects of the insecticide Phosdrin (mevinphos) and the herbicide Bladex on root tips of Tradescantia and Vicia faba were observed and compared with those of the chemical mutagen ethyl methane sulfonate (EMS). In addition, plants of Vicia faba were sprayed prior to floral initiation and pollen mother cells examined for chromosomal abnormalities. Phosdrin and Bladex produced the same kinds of chromosome abnormalities as EMS, namely, fragments, bridges, multipolar anaphases and lagging chromosomes. Bladex produced a higher percentage (3.47%) of chromosome aberrations in root tips of Tradescantia than did Phosdrin (2.56%), but fewer in Vicia faba than did either EMS or Phosdrin. Bladex was more toxic to cells of Vicia faba. The greater percentage of chromosome fragments induced by both pesticides in Vicia faba may be the result of highly specific and localized action of the pesticides in heterochromatic regions. Vicia faba seedlings sprayed with Phosdrin had a greater percentage of chromosome aberrations in the pollen mother cells than were found in root tips after Phosdrin treatment. Bladex sprayed at the same concentration as Phosdrin (200, 400, 600 ppm) was lethal to the plants. The frequency of chromosomal aberrations induced by both pesticides deviated significantly from that of the control.

Telomeric Association

Idiosyncratic chromosome behaviour during meiosis was found in pollen mother cells of Cuscuta babylonica Choisy, a thread-like holoparasitic herb. Its main features are among the following: (i) telomeric association between homologues through most stages of the process, which leads to persisting chromatid bivalents (= "demibivalents"); (ii) uncommon chromosome segregation in first and second anaphase; and (iii) prolonged intensified heterochromatinization. Although "regular" in its own way, this process leads to the formation of unviable products. Its further investigation might contribute to our understanding of the role of the spindle and chromosome movement in the ordinary process of meiosis. Key words: meiosis (abnormal), persisting demibivalents, Cuscuta babylonica.

Seedlings at different stages of development were treated with colchicine. Successive selections on the aspect of the seedlings soon after treatment, on size of the guard cells at the time of repotting, and finally, after overwintering, on counts of the chromosomes in the pollen mother cells yielded a few hundred plants with tetraploid crowns. These plants bore fewer, broader leaves and fewer, bigger inflorescences with larger achenes than did selected large-celled diploids given the same treatment, but in general the plants were no bigger. A few of the tetraploids were self-fertile (if not apomictic) early in the spring, but later all tested plants proved self-sterile.
