<![CDATA[Response of shoot of cactus (Mammillaria myriacantha) to various concentrations of NAA and BAP in Vitro Mardhiah Hayati Fakultas Pertanian Unsyiah Darussalam Banda Aceh ABSTRACT The research was arranged in a factorial completely randomized design 3 x 3 with 5 replicates. Factors evaluated were concentration of NAA (0, 2, 4 mgl-1), and concentration of BAP (0, 3, 6 mgl-1). Variables observed were initiation time, shoot numbers, shoot height, root number at 2 and 4 weeks after culturing (WAC) and life percentage, dead percentage, contamination percentage. The results showed that NAA significantly affected initiation time and shoot numbers at 4 WAC. The best initiation time was found at concentration of NAA 4 mgl-1 and the best shoot numbers was found at concentration of NAA 2 dan 4 mgl-1. BAP had significant effect on shoot number 4 WAC, shoot height 2 WAC, and root numbers at 2 and 4 WAC. The best shoot numbers and shoot height were found at BAP 3 mgl-1 but did not significantly differ from BAP 6 mgl-1. The best root numbers, however, was at no BAP. There was no significant interaction between both factors. ]]>
