| Abstract | ||||
| The objective of this paper is to study the effect of coating temperature and its duration on germination percentage of some medical and aromatic crops (fennel, caraway, coriander, nigella and guar) seeds. The main results in this study can be summarized in the following points: The fennel, caraway, coriander, nigella and guar seeds germination decreased by 22.5 – 22.9, 22.8 – 24.4, 18.9 – 29.8, 20.1 – 27.5 and 18.1 – 23.7 % by increasing coating temperature from 40 to 70 Co. Meanwhile, the fennel, caraway, coriander, nigella and guar seeds germination decreased by 16.7 – 35.4, 17.1 – 36, 16.6 – 32.3, 15.2 – 32.2 and 14.3 – 29.8 % by increasing coating time from 30 to 60 min. The maximum fennel, caraway, coriander, nigella and guar seeds germination of 98.1, 96, 98, 100 and 100 % were obtained with coating temperature of 40 Co and coating time of 30 min. Meanwhile, the minimum fennel, caraway, coriander, nigella and guar seeds germination of 63.38, 61.43, 66.3, 67.76 and 70.2 % were obtained with coating temperature of 70 Co and coating time of 70 min. | ||||
