| 摘要: |
| 低温反应敏感型供试品种中有不发生SGo（外层型二次生长）和SGi（内层型二次生长）及不发生SGo只发生SGi两类。播种前40d用35℃处理蒜种使SGi减轻；鳞芽分化发育期光周期对SGi的发生影响不大。低温反应中间型包括发生SGo和SGi及不发生SGo只发生SGi两类品种。5℃处理蒜种诱发SGo和SGi，35℃减轻SGo的发生，但有使SGi加重的趋势。光周期对SGo的发生无明显影响，12h以下短日照促进SGi发生。低温反应迟钝型品种一般不发生SGo只发生SGi．5℃处理蒜种或12h以下短日照对SGi的发生有利。 |

| Abstract: |
| Cultivars of Low Temperature Sensitivity Type used in this test included two kinds, i.e. non-occurance of secondary grow th of outlayer type (SGo) and secondary grow th of inner-layer type (SGi), and non-occurance of SGo but SG i. SGi was lowered by seed clove treatmentwith 35℃ for 40 days before planting. Photoperiodical treatment during clove differintiation and developmentperiod had less influence on SGi.Cultivars of Low Temperature Middle Type included two kinds, i.e. occurance of both SGo and SGi, and non-occurance of SGo butSGi. SGo and SGi were promoted by seed clove treatment with 5℃, and SGo was lowered by 35℃, but it tended to increasing SGi.Photoperiodical treatment had less influence on SGo, while SGi was promoted by daylength below 12 h. Cultivars of Low Temperature Inactivity Type generally was non-occurance of SGo but SGi. Seed cloves treated by 5℃ or the daylength below 12 h during the clove differentiation and development period favored the occurance of SGi. |
