DOES JASMONIC ACID PREVENT THE GERMINATION

Kürşat ÇAVUŞOĞLU

Özet


Abstract: Effect of jasmonic acid on seed germination and seedling growth of barley (Hordeum vulgare L. cv. Bülbül 89) was investigated in the present study. Jasmonic acid concentrations less than 1500 µM have not inhibited the seed germination, while 1500 and 2000 µM jasmonic acid levels caused atypical germination. The germination was completely inhibited at 3000 µM level of jasmonic acid. However, the seedling growth clearly slowed down with increasing concentrations of jasmonic acid. Furthermore, these inhibitions on the seed germination and seedling growth were irreversible.

Key words: Hordeum vulgare, jasmonic acid, seed germination, seedling growth
