吉林市磨盘山草本植物种类及其多样性

对吉林市磨盘山草本植物种类及其多样性进行了研究,结果表明:在研究区域内,草本植物有36种,分属21个科,29个属,其中菊科植物最多,其次为百合科、蔷薇科等.根据物种的重要值计算结果发现优势度最大的为丝引苔草,其次为宽叶苔草、铃兰、唐松草、莫石竹等.利用多个多样性指标统计科、属、种多样性指数,结果为Shannon指数依次为1.019 5,1.092 4和1.295 1,均匀度指数分别为0.334 9,0.324 4和0.361 4,优势度指数分别为0.146 8,0.121 1和0.081 1.     

邻体干扰推广模型及其在林草生态系统的应用

在对邻体干扰指数模型进行推广的基础上,将其应用于分析林草生态系统（杜仲－三叶草,杜仲－黑麦草,杜仲－蒿类）中杜仲生长速度与草本植物邻体干扰强度的定量关系。     

δ^13C and water-use efficiency indicated by δ^13C of different plant functional groups on Changbai Mountains,Northeast China

Leaf δ^13C of different plant functional groups （trees, shrubs and forbs; evergreen and deciduous; annual, biennial and perennial） were examined on the Changbai Mountains, China. Life form has a significant influence on plant δ^13C, suggesting that leaf δ^13C is also ideal for distinguishing functional groups species in temperate and frigid zones with high humidity. Additionally, the difference of water-use efficiency （WUE） is significant among different plant functional groups. δ^13C and WUE are in the following order of forbs 〈 shrubs 〈 trees. Within shrubs, δ^13C and WUE are higher for evergreen shrubs than deciduous shrubs. Differences in δ^13C and WUE are significant among different lifespan herbs, and δ^13C and WUE follow the order of annual herbs 〉 biennial herbs 〉 perennial herbs, not in accordance with the pattern obtained by previous studies in deserts, suggesting that the ranking of δ^13C and WUE among annual, biennial and perennial herbs may be dependent on local water availability.     

与“牛”有关的植物

牛至是唇形科牛至属多年生的半灌木或草本植物,生长在海拔500~3600米处。其植株矮小,没有明显的主干,地上的茎和叶在春季长出,到冬季枯萎,而地下的根和茎能存活多年。     

鸡冠花止血作用机制研究

目的 通过动物实验研究鸡冠花的止血作用及机制。方法 采用随机分组法,将16只家兔分为对照和实验2组,每组8只,雌雄各半,对照组以蒸馏水 灌胃,实验组以0．8g/kg剂量鸡冠花液灌胃,连续14d。结果 实验组家兔凝血时间较对照组明显缩短（P＜0．05）,而血中维生素C（VC）和钙（Ca^2 )质量浓度较对照组明显增高。结论 鸡冠花具有明显止血作用,其止血机制与其所含的丰富营养素Ca^2 和VC有关。
