Laboratory tests for predicting seedling emergence of sesame (Sesamum indicum, L.) cultivars in field

In order to determinate the best laboratory test for predicting emergence and establishment of sesame seedlings (Sesamum indicum, L.) at field condition, an experiment was conducted in two parts using six cultivars (Yellow-white, Darab14, Sari, Gorgan, Osbomahaleh and Shiraz). Results showed that there were no significant differences among cultivars for standard germination test, seedling dry weight and seedling length. But electrical conductivity test, germination rate and germination percentage after accelerated aging for 24 and 48 hours at 45°C showed significant differences among cultivars. The results showed that electrical conductivity test and accelerated aging for 48 hours at 45 °C can well predict the percentage of seedling emergence at field. Therefore, these tests can be suggested for prediction of sesame seed emergence.
