Behavioural studies on the methanol leaf extract of Securinega virosa (Euphorbiaceae) in mice

Securinega virosa is used traditionally in the West African region as sedative in children and in mental illnesses. In this study, the behavioural effects of the methanol leaf extract of S. virosa were investigated in mice at doses of 25, 50 and 100 mg/kg, using diazepam-induced sleeping time, hole board and beam walking assay, all in mice. The results revealed that the extract at the highest dose tested...

Inbreeding and fertility in Egyptian clover, Trifolium alexandrinum

Selection for manual tripping (MT) was effective in improving self-fertility (SF) in all populations and generations over original parents. Selection for MT was accompanied by improving fertility of open pollinated (OP) populations. Self-seed set (ST) was very poor. Some individual selections set seeds up to 88% in MT materials. The enigma of fertility, sterility and absence of inbreeding depressions in berseem was...
