Investigation of Ecological and Habitat Characteristics of Ochradenus Ochradeni Abdallah Species (Case Study: Bahman, Abarkouh, Yazd Province)

Abstract

The present study investigated some habitat characteristics and ecological of Ochradenus ochradeni Abdallah in Abarkouh Bahman area for possibility of restoration function. Geomorphology, climatic and phenology and biometrical characteristics of the population were investigated. Results showed the habitat had a middle to coarse soil texture with relatively high CaCo3 38.7± 26.07% and low CaSO4 2H2O, 0.19± 0.2% and pH equal of 7.1-8.5. The habitat of this species in some parts in bare pediment with low slope. Vegetation canopy of of the studied plant was low equal to 0.39%. Rainfall in all habitats was low and in Hossein Abad was 61.8 and in Bdaf was 47mm annually. The dry period of 10 months and monthly and annual distribution of rainfall was irregular. The highest number of accompany species equal to 52% belong to Chenopodiaceae. Growth season start at spring until mid-August and seeding stage is at summer until mid-August. Autumn and winter was equal to dormancy of this species. The highest germination percentage observed in KNO3 1% equal to 86.66% and KNO3 2% equal to 76.66% .Highest germination rate happened in KNO31% equal to 5.69 number per day. The lowest germination percentage and germination rate measured in moist chilling (in both 2 and 4 weekends) equal to 0.38%. Results showed this species grows from saline-sodium soils to non-saline-sodium soil. Therefore, it can be useful for rangeland restoration and saline soil improvement. This species are suitable for livestock feed and improving of vegetation through a scientific range management.
