A simple method was developed to permit albino plant regeneration from anther culture of Hobigonj Boro (Hbj B) IV and Hbj B VI, two local varieties of aromatic indica rice from Bangladesh. Three crucial factors were identified for the albino shoot primordia to change into green plantlets in culture; components of M10 induction medium, callus size (range 0.2-0.4 cm long) and height of shoot prim...

Present study was undertaken to determine the median lethal dose (LD50) of β-cyfluthrin (β-cyf), a synthetic (type II) pyrethroid pesticide in male and female Swiss albino mice. The calculation of LD 50 is an initial screening step in the assessment and evaluation of the toxic characteristic of a chemical substance. The selected single doses of β-cyfluthrin based on the pilot study were 200, 22...
