Effect of Exogenous Hormones and Chilling on Dormancy Breaking of Seeds of Asafoetida (Ferula assafoetida L.)

Abstract:
Asafoetida (Ferula assafoetida L.) is a medicinal plant with a problematic seed germination. Seeds of this plant have a long dormancy. The present research was carried out to investigate whether exogenous application of the hormones Gibberellic Acid (GA3), N6-furfurylaminopurine (kinetin) and 6-benzylaminopurine (BAP), alone or in combinations and chilling (for 0 or 28 days) could be used to alleviate the problem of dormancy. Germination was increased from 53.3% in a medium free of any hormones to 74.4% in a medium supplemented with 0.25 mg L-1 BAP. This was the only single hormone treatment giving a statistically significant increase in germination. Chilling increased germination from 37.5% (0 days of chilling) to 82.9% (28 days of chilling). Combining exogenous application of 0.25 mg L-1 BAP with 28 day chilling even gave more than 90% seed germination. Present findings suggest that seeds germination of Asafoetida can be greatly improved by combining chilling with BAP application.

mahmoud otroshy:

Dear achin we are a team that working on micropropagation medical plants such as assafoetida and others by in vitro culture. we have found a direct and indirect method for micropropagation of assafoetida. Now we are optimizing that in and may be within next 3-4 months it would finilised. Please contact me in next 3-4 months. Best wishes and success Mahmoud Otroshy Assistant professor Agricultural Biotechnology Research Institute of Iran Tel: 0098-331-223-4694, 0098-331-223-5858 Fax: 0331-2234587 Postcode: 85135-487 Isfahan-Najafabad Mobile: 0098-913-368-762 E-mail: [email protected]
