Abstract :

In this study, pepper seeds (cv. Yalova çarliston) were primed with herbal teas of dried petals of marigolds (Tagetes erecta and Tagetes patula) and oil rose (Rosa damascena) at 15ºC for 32 hours in a bubble column. Dry seeds were used as control. Standard germination (25ºC), low temperature stress (15ºC), emergence test in sand and also seedling quality parameters were determined at control and primed seeds. According to results, the treatments were significantly affected the normal seedlings percentage, mean germination time and seedling length, while the treatments were not effective on germination and abnormal seedling percentage in standard germination test. The highest normal seedling percentage was obtained from T. erecta herbal tea as 94.5% and the lowest normal seedling percentage obtained from control as 90.0%. Mean germination time decreased in primed seeds between 0.4 and 0.8 days compared with control. Herbal teas significantly increased seedling length and the highest length was determined from T. patula herbal tea as 12.4 cm. Similar results were obtained from low temperature (15oC) germination and emergence in sand as in standard germination test. The effects of priming treatments on seedling quality were not significant. As a result, it can be said that further researches are needed to use marigold and oil rose petals herbal teas as an organic priming agent for pepper seeds.
