| 摘要: |
| “苍山蒜”蒜瓣大小与二次生长(SG)的关系因播前蒜种贮藏条件和种植密度而异。室温贮藏蒜种,大蒜瓣比小蒜瓣易发生外层型二次生长(SGo),而蒜瓣大小对内层型二次生长(SGi)的发生无显著影响。播前25～30d进行冷凉处理的蒜种,蒜瓣愈大,SGo愈严重;小蒜瓣一般比大蒜瓣易发生SGi。种植密度对SGo的发生无显著影响,但稀植对SGi的发生有极显著的促进作用。不论种植稀密,大蒜瓣SGi指数都比小蒜瓣高。 |

| Abstract: |
| The relationships between seed clove size of garlic cv "Cangshan" and secondary growth varied with their storage conditions before their planting and planting density．When seed cloves were stored at room temperature(21～28℃)，the larger cloves had secondary growth of outer layer type(SGo)easier than the smaller ones，but the seed clove size had no significant effects on secondary growth of inner layer type(SGi)．When seed cloves were treated at cool temperature(16～17℃) for 25～30 days before planting，the larger the size of seed clove is,the more serious the SGo is，but the smaller seed cloves had SGi easier than the larger ones．Planting density had no more effects upon SGo．but
the occurence of SGi was promoted by planting too far apart. Whether it be in planting too far apart or too closely，the larger seed cloves have always more serious SGi than the smaller ones． |
