摘　　要：通过室内育苗移栽观察的方法,对细叶韭一年实生苗发育节律生物学特性进行了研究。结果表明:细叶韭种子萌动时间较长,14～15 d;细叶韭子叶双折呈弯曲状出土,子叶的前端长出地面,标志着植株与种子分离,植株从种子吸收养分的过程结束。细叶韭植株当年即按一分为二的方式进行分蘖,条件适宜时,当年生植株可以进行三级以上的分蘖。典型的二级分蘖以后的植株保持3片绿叶,即两叶一心;由于一年生细叶韭植株分蘖现象的发现,细叶韭一年生植株生育时期的划分应增加分蘖期。The biology characteristics of developmental rhythm of annual plants of Allium Tenuissimum L.were studied by observing seedling in glass ware transplanting in flowerpot.The results showed that：The Allium Tenuissimum L.seeds took 14～15 days to bourgeon.Cotyledons of Allium Tenuissimum L.growth came out of soil by double folding,cotyledons＇ front came out of soil was a sign that the plant separate from the seed and the process of plant absorbing nutrients from seed were over.Allium Tenuissimum L.plants could carry on tiller by one dividing in to two plants in the first year.Anual plants of Allium Tenuissimum L.could tiller over three stage under suitable conditions.The typical plants after secondary tiller had three green leaves.Tiller of anual plants of Allium Tenuissimum L.was discovered,so its growth period should add a stage i.e.tiller stage.
