Abstract: 

Trigonella belpngs to Papilionaceae. According to Flora Iranica, 32 species of it have grown in different parts of Iran. It is a medicinal, range and cultivated plant with many applications and uses in the traditional medicine and as a forage crop. Considering the different reproduction problems of this species through seed and importance of rehabilitation of its natural habitats, in this investigation, germination of the Trigonella was studied by different factors, such as chilling, hot water, seed wash, treatment with sulfuric acid and scarification. An experiment was conducted as split plot factorial in completely randomized design with 3 replications (each replication contains 50 seeds). Germination percentage, average time for germination, value of germination and germination rate were calculated. Comparing the averages had done with Duncan's test in 5% level. The results showed that these factors expect scarification with emery paper, had not effect on seed germination but scarification (2 minutes) for T. monspeliaca, T. uncata, T. stellata, T. anguina, T. astroits and (3-4 minutes) for T. elliptica and T. spruneriana showed considerable effects on the seed germination. Germination percentage for T. monspeliaca, T. uncata, and T. stellata reached to 100%, for T. anguina reached to 95%, for T. astroits achieved to 95% and for T. elliptica and T. spruneriana achieved to 75%. It seems that the hard coat of the seeds may be responsible for the lack of germination in native species.
