Seeds of 14 Iranian and one Indian cumin landraces were grown to produce freshly matured seeds. Freshly matured seeds were tested for germination, embryo and seed size, fresh and dry weights. Fresh seeds were after ripened at the room temperature for 4 or 20 months and were tested for germination. The effects of cold stratification, gibberellic acid (GA₃), and incubation temperature investigated on germination of three landraces. Results indicated that the highest embryo length: seed length (E:S) ratio was observed in Qaen (0.33), and the lowest ratios belonged to Heydarabab (0.22) and Jat (0.23) at the maturity. Cumin seeds germinated almost >80% from 5 to 20 °C after 20 months of dry storage. Germination of cumin seeds reached to the highest value in 8 weeks stratified (at 2 °C) seeds when seeds incubated at 15 °C. GA₃-soaked seeds had significantly higher germination percentage and rate compared with unsoaked seeds. Therefore, the physiological part of dormancy released during dry storage (after ripening) or cold stratification. GA₃ improved the rate of germination and its capacity. The embryos grew well from 5 to 20 °C when they were fully after ripened. Thus, seeds of cumin must have non-deep simple of morphophysiological dormancy.

生长了14个伊朗小茴香和1个印度小茴香地方品种的种子，以生产新鲜成熟的种子。测试新鲜成熟的种子的发芽，胚芽和种子大小，鲜重和干重。新鲜种子在室温下成熟4或20个月后进行发芽测试。冷分层，赤霉素（GA ₃），并研究了三个地方品种萌发的孵化温度。结果表明，在Qaen（0.33）中观察到最高的胚长：种子长度（E：S）比，在成熟时最低的是Heydarabab（0.22）和Jat（0.23）。干储存20个月后，小茴香种子在5至20°C的温度下发芽率几乎> 80％。当种子在15°C下孵育时，小茴香种子的发芽在8周内分层（在2°C下）种子达到了最高值。与未浸泡的种子相比，GA ₃浸泡的种子具有更高的发芽率和发芽率。因此，在干燥存储（成熟后）或冷分层期间释放的休眠生理部分。GA ₃提高了发芽率及其能力。胚胎完全成熟后，在5至20°C的温度下生长良好。因此，小茴香种子必须具有非深浅的形态生理休眠状态。
