To achieve this aim, marigold planted in pots and jasmonic acid were sprayed on the shoots at concentrations of 0.75, 150 and 225 μM. Data were compared by Duncan test. The results showed that different concentrations of jasmonic acid significantly affected the dry flower weight, plant height and 1000-seed weight. The maximum plant height and 1000-seed weight were reached by 150 μM jasmonic acid, while 225 μM was recorded the dry flower weight.</p> ER -
