Title Germination of Salicornia bigelovii (Torr.) under Shrimp Culture Effluents and the Application of Vermicompost Leachate for Mitigating Salt Stress
Source Agronomy-Basel
Author Keywords Salicornia bigelovii halophyte vermicompost aquaculture effluent organic crop salt stress
Abstract Attenuators of salt-stress favor the use of effluents, being a low-cost organic product. The present study aimed to evaluate the effect of vermicompost leachate (VL) added to shrimpculture effluent on seeds and seedlings of Salicornia bigelovii (Torr.) under salt-stress, evaluating germination, water relations variables, and biomass. Seeds were irrigated with distilled water (DW) (CE: 0.0027 dS m(-1)), freshwater (FW) (CE: 1.36 dS m(-1)), seawater (SW) (CE: 55.83 dS m(-1)), shrimp residual water (SRW) (CE: 59.85 dS m(-1)), and with the same water sources but adding VL in 1:20 v/v. The means for the index of germination rate (IGR), germination energy (GE), and germination time (MGT) were higher with DW, DWVL, FW, and FWVL, decreasing with the others (p <= 0.05). In seedlings, the lowest water potential (Psi w) and osmotic potential (Psi s) were observed with SW, SWVL, SRW, and SRWVL (p <= 0.05), evidencing higher stress but the highest relative water content (RWC). The fresh and dry biomass increased and showed significant differences with SRW, and adding VL (DWVL, FWVL, SWVL, and SRWVL) acted as an effective attenuator of salt-stress. The response of water relations variables suggested an osmotic adjustment for mitigating the salt-stress in seedlings, lowering the Psi w and Psi s but increasing the RWC.
