| 摘要: |
| 供试的低温反应敏感型生态亚型2品种,在各温光处理组合中均保持其不完全抽薹特性。低温反应中间型品种,在自然日长下,蒜种播前用20℃或35℃处理40 d可正常抽薹; 16 h日长一般对抽薹无影响; 12 h日长下,蒜种用20℃或35℃处理者,多数品种仍可正常抽薹; 8 h日长对抽薹不利。低温反应迟钝型中多数品种在各温光处理组合中不抽薹或不完全抽薹,但有少数品种,蒜种用5℃低温处理,在自然日长下也可正常抽薹。 |

| Abstract: |
| The inherent characteristics of umcomplete bolting cultivars of subecotype 2 of Low Temperature Sensitivity Ecotype remained unchanged under all temperatue and photoperiod treatment combinations.Cultivars of Low Temperature Middle Ecotype bolted normally under natural daylength when seed cloveswere treated with 20℃
or 35℃ for 40 d before planting.Generally, 16 h daylength had no influence on bolting.
Most cultivars of this ecotype bolted normally under 12 h daylength when seed cloves
were treated with 20℃ or 35℃, but 8 h daylength had unfavourable influence on bolting.
Most cultivars of Low Temperature Inactivity Ecotype were unbolting or uncomplete
bolting under all temperature and photoperiod combinations, buta small number of cultivars may be bolted under natural daylength when seed cloves were treated with 5℃. |
