Abstract

Abstract: Diurnal variation and its influencing factors of leaf water potential (ψ_l) of Spinifex littoreus on the nebkhas in two succession periods were measured on the coast of Pingtan Island, Fujian Province. The results showed that the diurnal variation of ψ_l of S. littoreus mainly demonstrated a ‘W’ curve pattern, with a temporary rise at midday. The mean ψ_l of S. littoreus on the nebkhas at developing stage was higher than that at stabilizing stage, and recovered better during the night. ψ_l of S. littoreus was positively related to the atmospheric water potential (ψ_a) and relative humidity, negatively related to air temperature, but had no significant correlation with the soil water potential at different depthes. ψ_l of S. littoreus on the interdune depression at developing stage was higher than that on the windward slope and on the leeward slope from 10:00 to 16:00, and that on the windward slope was lower than that on the leeward slope all day long except at 10:00 and at 12:00. The variation of ψ_l of S. littoreus on the leeward slope was higher than that on the windward slope, and the minimal variation was found on the interdune depression, without statistical significance. ψ_l of S. littoreus on the windward slope was positively correlated with ψ_a and relative humidity, while negatively correlated with air temperature. ψ_l of S. littoreus on the leeward slope and the interdune depression were correlated with meteorological factors, but they had no significant relationship.
