A meiotic examination of Lolium multiflorum Lam. X Festuca arundinacea Schreb. F1 hybrids


, : A meiotic examination of Lolium multiflorum Lam. X Festuca arundinacea Schreb. F1 hybrids. Crop Science 22(2): 305-309

Meiotic chromosomal behaviour was examined in two F1 hybrids. The hybrids displayed similar frequencies of bivalents (82.5% and 84.1%) and trivalents (2.3% and 3.0%) per cell but differed significantly in the frequencies of univalents and quadrivalents at metaphase I. The number of lagging univalents observed at anaphase I corresponded well with the number of micronuclei per dyad at interkinesis. The number of quartet micronuclei was similar for both hybrids.

Pyrethroid insecticides have potent actions on voltage-gated sodium channels (VGSC), inhibiting inactivation and increasing channel open times. These are thought to underlie, at least in part, the clinical symptoms of pyrethroid intoxication. Howe...
