Abstract:
This study aims to determine the response of the growth of fragrant roots (Vetiveria zizanioides) on ascorbic acid in salinity stress. The study was conducted using factorial randomized block design, conditions of two factors, the first factor was salinity (S), consisting of 2 levels: S0: No Salinity (0 dsm-1) and S1: Salinity (4 dsm -1). The second factor was ascorbic acid (A), conditions of four levels, A0: No ascorbic acid, A1: 50 ppm, A2: 100 ppm and A3: 150 ppm. There were 8 treatment combinations that were repeated 3 times in 24 experimental units. The parameters observed were plant height, number of leaves, now her of leaf chlorophyll, number of stomata, bottom dry weight, top dry weight, number of clumps and root volume. The result showed that ascorbic acid had significant affect on the parameters of plant height, number of leaves and the number of stomata. Ordinary soil had significant effect on the parameters of the number of stomata and there was no interaction on all parameters observed.
