| Abstract: | The aim of this research was to observe the responses of red galangal (Alpinia purpurata (Vieill.) K. Schum.) growth on treatment of water levels and mycorrhizal inoculation.This research used experimental method with randomized complete block design. Treatments included two factors: (1) the inoculation of mycorrhizal consisting of two levels i.e. non-mycorrhiza and mycorrhizal plants, and (2) the water content consisting of five levels i.e. 0%, 20%, 40%, 60%, and 80%. Each treatment was repeated three times. Observations were conducted at 10 weeks after planting on the parameters of plant height increase, number of buds, stomatal density, dry weight, chlorophyll content, and percentage of mycorrhizal infection degree. The data were analyzed using Analysis of Variance (ANOVA) and posthoc with Duncan Multiple Range Test (DMRT) at α 5%. The results showed that in the water content of 40%, the red galangal growth still showed normal growth, which can be seen in the parameters of plant height increase, number of shoot, stomatal density, dry weight, chlorophyll content, and percentage of mycorrhizal infection degree. |
