Abstract

In order to examine seed GERMINATION responses of KOCHIA to different levels of SALINITY, an experiment was performed in the Institute of Sustainable Agriculture (CSIC), Cordoba, Spain, in a completely randomized design with two replications. Treatments were different levels of salinities equal to 0,5, 10, 15, and 20 ds/m, obtained by mixing NaCl and CaCl2 in a 2:1 molar ratio. Evaluated properties were GERMINATION percentage, rate and final number of germinated seeds. The results showed that the germinated seed number and the GERMINATION percentage had a converse relation with SALINITY levels. About 91% of seeds were germinated in distilled water.This value reduced to about 36% in 20 ds/m. Increasing SALINITY up to 10 ds/m did not have any significant effects on GERMINATION, but after that, the GERMINATION rate and percentage begun to reduce significantly. SALINITY also increased the time required for 50% GERMINATION from 28 hours in distilled water to 78 hours in 20 ds/m, showing a delay in GERMINATION as SALINITY increased. Regarding linear reduction in GERMINATION rate in response to increase in SALINITY, it , seems that as SALINITY exceeds 30 ds/m, GERMINATION rate of KOCHIA approaches zero. This perhaps could be accepted as the threshold of KOCHIA GERMINATION tolerance to SALINITY. According to the results, the GERMINATION stage of KOCHIA has a good tolerance to elevated levels of SALINITY and it seems that a good stand establishment in saline soils and water conditions could be insured, if proper management is exerted in farms.
