Growth regulators especially auxins and cytokinins are critical for plant in-vitro regeneration. The effect of these plant growth regulators on in-vitro propagation of Saccharum officinarum L (Sugarcane) was investigated. In vitro response of two different varieties of sugarcane (NCS 005 and NCS 008) to Plant Growth Regulators was obtained in this study. Formation of buds was obtained on shoot apical meristem when cultured on MS (Murashige and Skoog) medium supplemented with 0.1mg/l BAP (6-Benzylaminopurine). After two weeks of initiation, regenerated meristem was inoculated into MS (Murashige and Skoog) fortified with different concentrations and combination of cytokinins. Shoot multiplication was optimal on 0.5mg/l BAP + 0.25 mg/l Kin(Kinetin) for NCS 005 variety while for NCS 008 variety, no significant (P≥0.05) difference was observed between 1.5mg/l BAP and 1.5mg/l BAP +0.5mg/l Kin. The best root induction for in vitro derived shoots was obtained on 1.0 mg/l NAA (Naphthalene acetic acid) and 2.0 mg/l IBA( Indole butyric acid) for both varieties of sugarcane within ten days of culture transfer. Successfully established plantlets showed excellent growth response when weaned under regulated green house conditions.

The study which was a survey investigated teachers' perception of adolescents' violence in secondary schools in Awka Education zone of Anambra State. The study was guided by three research questions and two null hypotheses stated at .05 level of significance. A sample of 400 out of 1,863 teachers responded to the questionnaire items. The data generated through the questionnaire were statistically analysed using mean, standard deviation and t-test statistics. The study found out that such forms of violence as destruction of school property, fighting, kicking, bullying, pushing, breaking and destroying other students' lockers and personal belongings, cultism, riots, beating teachers, flogging the junior students by the senior ones are prevalent in secondary schools. Again the study revealed that the degree of adolescents' involvement in violence is relatively very high. In view of the findings of the study, recommendations of the study were highlighted.
