Abstract

The vetiver plants were appertained to the Gramineae family, densely clumped. The ecotypes from plants were distinct a pattern besides at environmental situation in geographical areas of the variety. In this study, we were determined to growth to various ecotypes of vetiver at different salinity levels. This research was used a factor complete random design in two (2) factors. Then, the first factor included salinity (S) which consists of 6 levels (: So: without salinity, S1: saline soil 4 dsm-1, S2: saline soil 8 dsm-1, S3: saline soil 12 dsm-1, S4: soil copy 16 dsm-1, S5: soil saline 20 dsm-1). The second factor was the Ecotype (E) which consists of 3 levels (E1: Bogor Ecotype, E2: Bojonegoro Ecotype, E3: Padang Ecotype). Results were found that the vetiver ecotype has a significant role on the various levels from salinity in the observations of plant height at 6 WAP, number of leaves at 6 WAP and number of tillers at 8 WAP. Thus, this study obtained vetiver ecotypes that were able to survive at several levels of salinity stress.
