Abstract
|
|
|
Studies were conducted to find out seed germination behavior of spinach cultivars with different morphological and/or physiological characteristics. Major results are as follows.
1. Germination of small to medium sized seeds was much faster than that of large seeds.
2. Germination vigor (7 days after sowing) and germination rate (14 days after sowing) were markedly influenced by the temperature. Among the tested temperature regimes, best seed germination was obtained at 15℃.
3. Round seeds germinated much faster than prickly seeds at 4℃. However, the germination of round seeds was much slower than prickly seeds at 20℃ or higher. Most round seeds failed to germinate at 25℃ whereas prickly seeds showed about 40~ germination rate.
4. Decoated seeds (true seeds) germinated much better than intact seeds (fruits), especially at higher temperatures.
5. Excess moisture was definitely detrimental to spinach seed germination, especially to the germination of round seeds.
