Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...
laboratory experiments were performed to determine the effect of various scarification treatments at four temperature regimes on germination of licorice seeds . a randomized complete block design with four replications was used. germination counts were made every day for 2 weeks. at 50c, none of the chemically and mechanically scarified and non scarified seeds germinated. at 15, 25, and 350...
both poor germination and crop establishment due to water stress and salinity are among the most important limitations for production in semi-arid regions such as iran. to evaluate the response of four genotypes of triticale (et-82-15، et-82-8، et-79-17 and juanillo-92) to different water potentials caused by salinity and/or drought and recognizing the germination and seedling establishment, a ...
In order to study the effect of sodium chloride (NaCl), as a salinity stress factor, on sour orange seed germination indices, an experiment was conducted in a completely randomized design with 3 replications (each replication included 20 seeds) at the University of Guilan, in 2009. NaCl levels were 0, 7.8, 15.6 and 23.4 dS/m. The results showed that various levels of NaCl had significant effec...
