Notes:
Summary Floristic composition studied in a 40 hectares representative site of alkali soils in the Indo-gangetic plains of Northwestern India revealed a remarkably restricted spectrum of natural vegetation. Soil analysis of specific niches, occupied by aggregations of different species, was employed to identify alkali halophytes. Response functions of eight prominent species to increasing levels of soil alkalinity, studied in pot culture, showed that most of them were adapted to alkali soils. Based on the computed importance value indices and observed biomass production maxima, it has been inferred thatSporobolus marginatus, Sporobulus coromandelianus, Diplachne fusca andChloris barbata, qualify as plant indicators of high-alkali soil conditions.
