摘要:
 为探究干旱胁迫对不同宿根花卉生长的影响,通过盆栽控水方法测定24种宿根花卉在干旱胁迫下的株高、冠幅、根长及根冠比等生长指标,并根据各指标的旱水比值结合隶属函数法对其抗旱性进行初步排序。结果表明,干旱胁迫下所有试验材料的株高和冠幅均减小,根冠比和根长先增加后下降,抗旱性由强到弱依次为:马蔺>旱麦瓶草>菊叶委陵菜>‘金娃娃’萱草>二裂委陵菜>山麦冬>溪荪>叉分蓼>白屈菜>地被石竹>蓬子菜>蹄叶橐吾>蓝花棘豆>麻花头>展枝唐松草>华北蓝盆花>紫花耧斗菜>龙牙草>黄芩>草地风毛菊>地榆>路边青>‘小兔子’狼尾草>独活。
Abstract:
 In order to explore the effects of drought stress on the growth of different perennials,24 perennial flower species under drought stress were measured by pot water control method,including plant height,crown width,root length and root-shoot ratio.The abilities of drought resistance of 24 perennials were evaluated preliminarily according to the drought-water ratio of each index and the membership function method.Under drought stress,plant height and crown width of all tested materials decreased,root-shoot ratio and root length increased first and then decreased.The order of drought resistance of 24 perennial flower species was as follows: Iris lactea var.chinensis>Silene jenisseensis>Potentilla tanacetifolia>Hemerocallis fulva‘Golden Doll’>Potentilla bifurca>Liriope spicata>Iris sanguinea>Polygonum divaricatum>Chelidonium majus>Dianthus plumarius>Galium verum>Ligularia fischeri>Oxytropis coerulea>Serratula centauroides>Thalictrum squarrosum>Scabiosa tschiliensis>Aquilegia viridiflora f.atropurpurea>Agrimonia pilosa>Scutellaria baicalensis>Saussurea amara>Sanguisorba officinalis>Geum aleppicum>Pennisetum alopecuroides ‘Little Bunny’>Heracleum hemsleyanum.
