摘要:
作者以4个草地植物群落中的野生湿生扁蕾(Gentianopsis paludosa)为研究对象,通过测定花器的数量性状、生物量结构及生理生化差异,分析湿生扁蕾在不同群落中的花器形态数量及生物量分配的调节能力,以研究其应对或适应生境胁迫的生长策略的目的。结果表明:(1)群落组成对湿生扁蕾的株高和分枝数有极显著影响(P<0.01),高郁闭度利于株高和分枝数增加,高土壤含水量限制了株高和分枝数;(2)群落组成对花梗长、花枝数、花瓣宽、花瓣长、花管长均有显著影响(P<0.05),对花冠宽、花萼长影响较小(P>0.05),影响顺序为花梗长>花枝数>花瓣宽>花瓣长>花管长>花冠宽>花萼长;(3)群落组成对花瓣色素及抗性物质的影响均有极显著影响(P<0.01),其影响顺序为花青素>植物总酚>原花青素;(4)群落组成对单株生物量、生殖生物量、花梗干重、花干重有极显著差(P<0.01),对生殖分配比、花梗分配比、花分配比均有极显著影响(P<0.01),对其生殖含水量、花梗和花含水量及水分分配比影响很小(P>0.05);(5)相关分析表明,群落郁闭度与花梗生物量呈显著正相关(P<005),群落土壤含水量与花枝数/株和花管长呈显著负相关(P<0.05),群落高度与花梗生物量有显著负相关(P<0.05),生殖生物量和单株生物量与花枝数/株呈显著正相关(P<0.05)。
Abstract:
Taken wild Gentianopsis paludosa in four kinds of grassland plant community as research object,the quantitative traits of flower,biomass structure and physiological and biochemical index are measured for the purpose of analyzing flower morphology number and biomass allocation of G.paludosa in different communities and further discussing its growth strategy of coping or adapting to the environmental stress.The results show that:A.Community composition has a significant effect on its stalk height and branch number of G.paludosa(P<0.01),e.g.high canopy density is good for increasing its stalk height and branch number whereas high soil moisture content will be a restriction.B.Community composition has an obvious impact on its stalk length,spray number,petal width,petal length,floral tube length(P<0.05) but less effect on its corolla width and calyces length (P>0.05).The influence order goes like stalk length> spray number > petal width > petal length > floral tube length > corolla width > calyces length.C.Community composition has considerate influence on petal pigment and resistant material (P<0.01),and the influence order goes like anthocyanidin > total phenol > procyanidins.D.Community composition has a great effect both on the single plant biomass,reproduction biomass,stalk biomass,flower biomass (P<0.01) and on the reproduction biomass allocation ratio,stalk biomass allocation ratio and flower biomass allocation ratio (P<0.01) but little effect on reproduction water content,stalk water content,flower water content and water allocation ratio (P>0.05).E.Correlation analysis shows that positive correlation significantly existed between community canopy density and stalk biomass (P<0.05) whereas negative correlation is found between community soil moisture content and spray number,floral tube length (P<0.05).In addition,community height and stalk biomass are negatively related(P<0.05) whereas reproduction biomass is positively related to single plant biomass and spray number (P<0.05).
