【 摘 要 】
The aim of this study is to know the effect of root-up size and concentration on root potato growth on the number of different leaf stem leaves. This research was conducted using Randomized Complete Block Design at 3 factors and 3 replicates. The first factor was the Root-up Types [RT], consisting of RA, RB, RC, and Rotten-F (as a comparison); the second factor was Root Up Concentration [RC] consisting of C5%, C10%, C15%, C20%, and C25%); and the third factor was the Number of Leaf on the Cuttings [NL] consisting of NL-1, NL-2, and NL-3. The contrasting orthogonal test shows Root-Up vs Control treatment was highly significant in all observed variables, except in stem diameter was increased. Based on data analysis, the Root-up vs Control treatment had a very real effect on all variables, except in stem diameter increase. In Root-up treatment: RT-RC-NL, there were no significant interaction in all observed variables. In RT-RC, there were an interaction between shoot height increase, number of leaves, and root length. RTC with concentrations of 10-25% showed higher growth, better leaf count and root length. In RT-NL, interaction occurs on number of leaves, RTC with the number of leaves 1, 2, and 3 on the shoot cuttings showed a better number of leave. RC-NL occurred in the interaction of the increase in shoot height and number of leaves. RC of 20% with NL 1, 2, and 3 on shoot cuttings show highest increase and highest leaf number. Based on this study, the use of Root-up C with 10-20% concentration could be used as a reference for shoot cuttings multiplication.
