“…Also Arinaitwe et al (2000) and Gubbuk and Pekmezci (2004) revealed a significant effect of both types and concentrations of cytokinins on the multiplication rate. Arinaitwe et al (2000) also studied the effect of BAP on banana cultivars. They reported no significant increase in shoot proliferation in 'Kibusi' (AAA) and 'Ndiziwemiti' (ABB) from 16.8 to 28.8 µM, but the cultivar 'Bwara' (AAA) revealed significant increase in number of shoots from 16.8 to 28.8 µM.…”

“…Previous reports (Kalimuthu et al, 2007;Venkatachalam et al, 2007;Bairu et al, 2008) indicated that 22.2 µM of BAP is the optimum cytokinin concentration for most banana tissue cultures and thus support our results. Arinaitwe et al (2000) were the first to study of TDZ in Musa spp. Lee (2001) reported that the effect of TDZ on the multiplication rate varied among banana cultivars (AAA) and (AAB).…”

“…The shoot apices are used as the source materials for the establishment of in vitro shoot tip culture (Kulkarni et al, 2007). Different kinds of cytokinins have been used for micropropagation of banana cultivars (Arinaitwe et al, 2000;Roels et al, 2005) and shoot proliferation rate is significantly affected by cytokinin types, their concentrations and type of banana cultivars (Arinaitwe et al, 2000;Gubbuk and Pekmezci, 2004;Roels et al, 2005). Benzylaminopurine (BAP) has been mentioned to be the most commonly preferred cytokinin (Cronauer and Krikorian, 1984;Vuylsteke, 1998;Gubbuk and Pekmezci, 2004).…”

“…This results are in agreement with Arun et al,(2012), who reported 4.56 and 2.30 roots/plant on 0.5mg/l IBA+0.5mg/l NAA and 1.0mg/l IBA+1.0mg/l NAA fortified MS medium respectively. However, the appropriate amount of auxin in the rooting medium is crucial for the induction of the root Arinaitwe et al, 2000).…”

A B S T R A C TBanana is one of the most important and remunerative cash crops grown round the year in Ethiopia. The energy and nutritional status of banana are much higher than other common tropical and subtropical fruits. The objective of this study was to establish in vitro root development protocol in Poyo and Grand naine varieties from sucker. For root induction suckers of Poyo and Grand naine were cultured on MS basal medium that contained 30 g/l sucrose, 6 g/l agar and vitamins. Rooting of the shoots was done on full strength MS basal medium supplemented with different concentrations of IBA (0.5, 1.0, 1.5, 2.0 mg/l) and NAA in sole and in combination (0.5 mg/l IBA+ 0.5 mg/l NAA and 1.0 mg/l IBA + 1.0 mg/l NAA). In all cases, MS basal medium without PGRs was used as control. The rooted plantlets were then acclimatized under greenhouse conditions by transplanting the plantlets on moist red soil, sand soil and compost or their mixture in 2:1:1 ratio. Results showed that root formation responses were significantly (P<0.05) higher under all levels and combinations of hormones when compared with control treatments. For Poyo variety, 0.5mg/l IBA had higher response for root numbers and root length than at other treatments. Number of days to root emergence was found to be shorter at 20.mg/l NAA of hormonal level than other treatments. In the case of Grand naine variety, the concentration of 1.5mg/l IBA alone treatment had positive effects on multiple root formation and MS + 0.5 mg/l IBA for highest length of roots. The number of days for root emergence was found to be shorter at combination of 1.0 + 1.0mg/l IBA and NAA in grand naine. Compared to the control, both IBA and NAA alone or in combination showed significant positive effect on root formation of shoots of both varieties. The acclimatization experiment showed that plantlets of both varieties survived better on the sterilized mixture of moist red soil, sand and compost soil in a ratio of 2:1:1. Comparison of the performance of both varieties showed that Poyo showed superior performance compared to Grand naine variety with respect to all measured agronomic traits except field survival rate which found better in grand naine, suggesting that varietal difference for the difference in the response to the PGRs.
