| description | Okra seed hardness results in slow and nonuniform germination. This study was conducted to determine the effects of time of harvest and storage on seed germination of four different cultivars of okra (Abelmoschus esculentus L.). The study was carried out at Agricultural faculty of Razi University in years 2009 and 2010. The experimental design was a randomized complete block under factorial arrangement with three replications. Four different cultivars of okra included, Boiatloy, Beloudo, Clemsson Seinless and Pleas and six harvesting times of 20-25-30-35-40 and 50 days after flowering were considered in the present study. The results showed that seed germination increased in 2009 from 3.4%, at first harvesting time, to 46.4% at fifth harvesting time, and in 2010 from 2.9%, at the first harvesting time, to 49.7% at fifth harvesting time. Different cultivars varied in seed germination. In 2009 Plea and in 2010 Clemson cultivars showed the highest germination. Seeds from different parts of the plant also showed different germination rate. In 2009 seeds from the middle part of the plant with 54.3% and in 2010 seed from the lower part with 50.3 % showed the highest germination. In 2009 seeds from the lower part of pod showed more germination, whereas in 2010 seeds from middle part of pod produced higher germination. By increasing time to harvest, the percentage of seed germination after storage highly increased. Different cultivars during storage showed different behaviors on germination. Beloudo cultivar produced more seed germination than other varieties after storage, and Pleas after storage produced lower seed germination. Seeds from the middle part of plant and middle part of pod showed a higher germination after storage. |
