tailieunhanh - The increase in in vitro shoot multiplication rate of Dendrocalamus asper (Schult. f.) Back. ex Heyne

A method for micropropagation was developed for Dendrocalamus asper, an economically and environmentally important bamboo. Disinfected seeds were cultured in flasks containing 20 ml of Murashige and Skoog’s medium (MS) supplemented with BA ( mg l-1 ) or kinetin ( mg l-1 ). Multiple shoots () were formed on MS medium supplemented with mg l-1 BA and reached cm in length. Continuous shoot proliferation was achieved on a MS medium supplemented with BA ( mg l -1 ). The multiplication rate of fold was achieved on MS medium supplemented with mg l-1 BA. Propagules were excised from multiple shoots and transferred to rooting medium. After 4 weeks, high in vitro rooting was achieved on MS supplemented with mg l-1 IBA. cm in length root system developed roots in 28 days. A high rate of plant survival (85%) was obtained within 2 weeks. | The increase in in vitro shoot multiplication rate of Dendrocalamus asper (Schult. f.) Back. ex Heyne
