Abstract: (18981 Views)
Experiments were carried out in order to micropropagate sugarcane cultivars through shoot tip and auxilliary bud culture. Rinsing of four cultivars of sugarcane, namely CP-48-103, CP-57-614, CP-69-1062, and NCO-310 in 75% alcohol for 60 seconds and their subsequent disinfection with sodium and calcium hypochloride (1.5% active material) for 15 minutes decreased a significant amount of infection of explants in the medium. The use of the Murashing and Skoog (MS) solid and liquid medium with 1 mg/l Indole Butyric Acid (IBA), 1 mg/l Kinetin, 100 mg/l mio-inositol, 1 mg/l Thiamin HCl, and 2% sucrose had significant superiority (P<0.05) to 1/2 MS solid medium. Also, to increase the multiplication in a sterile medium (In vitro), two kinds of solid and liquid MS medium, with a hormone combination of 1 mg/l IBA, 2 mg/l Kinetin and 1 mg/l 6-(benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (BAP) were applied which yielded the highest amount of proliferation. The plants formed roots in Schenk and Hildebrandt (SH) medium with a hormone combination of 5 mg/l IBA and 1 mg/l Kinetin. When activate charcoal was used in the medium, a higher percentage of the plants became rooted and a larger number of adventitious roots were produced than in the dark-light or light treatments.
