    • 摘要: 苔草(Carex)为莎草科(Cyperaceae)苔草属(Carex L.)的多年生草本植物,具有耐荫、自繁能力强、多年生、种质资源丰富等特点,在园林绿化、草牧业生产、生态修复等方面发挥着越来越重要的作用.随着苔草属植物的广泛应用,种质资源进一步开发和新品种选育成为当前的重点,而遗传多样性研究是基础.本文综述了苔草属植物在形态、细胞及分子水平的遗传多样性研究进展.此外,还介绍了苔草属植物遗传多样性研究在新品种选育、品种鉴定、物种起源及亲缘关系、遗传图谱构建等方面的应用.最后对苔草属植物基因组开发、新品种培育进行展望,以期为今后苔草的遗传育种及进一步开发应用奠定基础.

    • 摘要: 以崂峪苔草、青绿苔草以及青绿苔草变种3种苔草属植物为试验材料,通过田间自然降温处理,分别测定各个时间段叶片相对电导率、叶绿素含量、光合速率以及叶绿素荧光,并采用模糊隶属函数法对3种苔草的耐寒性进行综合分析.结果表明,3种苔草随着气温的降低,相对电导率均呈上升趋势,崂峪苔草在12月8日之前上升最为缓慢,仅比11月16日提高了2.6%,而其他2种苔草与11月16日相比均提高11%左右;3种苔草叶片的原始光能转化效率(Fv/Fm)整体呈下降趋势,其下降幅度随胁迫强度的加剧和胁迫时间的延长不断变大;通过模糊隶属函数法分别计算各指标的隶属函数值得出,崂峪苔草、青绿苔草、青绿苔草变种的隶属函数值分别为0.551、0.509、0.439,可知3种苔草的耐寒性大小为崂峪苔草>青绿苔草>青绿苔草变种.

    • 摘要: 湿地自然水文节律的改变影响着湿地生态系统的稳定与安全.为探究湿地水文变化对土壤微生物活性的影响, 以鄱阳湖洲滩湿地3种典型植被狗牙根 (Cynodon dactylon) 、南荻 (Triarrhena lutarioriparia) 和苔草 (Carex cinerascens) 下表层土壤 (0~20 cm) 为研究对象, 对湿地土壤微生物呼吸、微生物生物量和水解酶等土壤活性特征进行连续3年的实验监测, 分析年际水位变化对不同植被湿地土壤微生物活性的影响.结果表明:丰水年显著提高土壤中养分的可利用性 (有机质、总磷、速效磷) , 提高土壤微生物生物量、微生物熵、水解酶活性, 表明丰水年有利于湿地生态系统的物质循环转化.水文条件也能通过影响湿地植被生长改变土壤养分状况, 进而对植被下土壤微生物活性产生显著影响.诸多土壤理化因子中, 可溶性有机碳是驱动微生物活性变化最关键的因子.进一步分析表明, 由植被类型所代表的长期水文累积效应对湿地土壤理化及微生物活性的调节作用大于单纯的年际水文变化.%The change of hydrological rhythm will affect the stability and security of wetland ecosystems. In order to explore the influence of annually hydrology variation on the soil microbial functional traits, we selected the surface soils (0-20 cm) under three different vegetation types—Cynodon dactylon, Triarrhena lutarioriparia and Carex cinerascens as study objects from the Lake Poyang wetlands. The soil activity characteristics of microbial respiration, microbial biomass and soil enzymes in wetland soils were tested in three consecutive years. The effects of annually water level changes on soil microbial activities in different vegetation wetlands were analyzed. The results showed that: The contents of soil available nutrient sources (including organic matter, total phosphorus, and available phosphorus) was enhanced in high flow years, as well as soil microbial biomass, microbial entropy and hydrolase activities, which were beneficial to material circulation and transformation of the wetland ecosystem. Hydrological conditions affected the state of soil nutrients by affecting the growth of wetland vegetation, and further affected the soil microbial functional traits. Among various soil physicochemical factors, dissolved organic carbon was the most critical factor driving the change of microbial functional traits. Further analysis showed that the long-term historical hydrological cumulative effects represented by different vegetations had greater impact on the soil physicochemical properties and microbial functional traits than the pure hydrological changes annually.

    • 摘要: 青绿苔草(Carex leucochlora)是北京地区的乡土草坪地被植物.为缓解园林灌溉和水资源紧缺之间的矛盾,实施节水灌溉,2012-2014年采用自动称重式大型蒸渗仪研究了青绿苔草草坪的蒸散特性,与北京地区代表性的草坪地被高羊茅(Festuca arundinacea)、野牛草(Buchloe dactyloides)、山麦冬(Liriope spicata)进行了对比分析,并对各种草坪地被的灌溉需水量进行估测.结果表明,青绿苔草在不同月份的蒸散速率不同,5月的蒸散速率最高为3.96±0.23 mm· d-1,月作物系数为0.73±0.09~0.95±0.03.青绿苔草草坪的蒸散速率高于同种地被.青绿苔草草坪地被的蒸散速率明显低于高羊茅草坪,略低于山麦冬地被,略高于野牛草草坪.以平均值计算,高羊茅、山麦冬、野牛草的蒸散速率分别是青绿苔草的1.40倍、1.11倍、0.98倍.充足水分供应条件下,生长季灌溉需水量从低到高为青绿苔草地被(110.9~136.2mm)、野牛草草坪(167.1 mm)、青绿苔草草坪(191.7 mm)、山麦冬地被(233.6mm)、高羊茅草坪(352.2mm).%Carex leucochlora is a native turf and groundcover species in Beijing area.In order to alleviate the contradiction between green-land irrigation and water resource shortage and to practice water-saving irrigation,the evapotranspiration (ET) characteristics of C.leucochlora was studied using large auto-weighing lysimeters.It was compared with three representative turf and groundcover species,Festuca arundinacea,Buchloe dactyloides and Liriope spicata.Irrigation water demand of these turfs and groundcovers was estimated.The results showed that the ET rate of C.leucochlora varied monthly,with the highest value of 3.96±0.23 mm · d-1 in May.Its' monthly crop coefficient was 0.73±0.09~0.95±0.03.The ET rate of the turf was slightly higher than the groundcover for C.leucochlora.The ET rates of both C.leucochlora turf and groundcover were the lowest among all the turfs and groundcovers,except the ET rate of C.leucochlora turf was slightly higher than that of B.dactyloides turf.On average,ET of F.arundinacea,L.spicata,and B.dactyloideswas 1.40,1.11 and 0.98 times of that of C.leucochlora,respectively.Under the sufficient water supply condition,the irrigation water demand during the growing season arranged from low to high:C.leucochlora groundcover (110.9 ~ 136.2 mm),B.dactyloides turf (167.1 mm),C.leucochlora turf (191.7 mm),L.spicata groundcover (233.6 mm),F.arundinacea turf (352.2 mm).

    • 摘要: 选取鄱阳湖湿地典型植物苔草为对象,通过野外采样,对苔草的土壤水 、植物水稳定氢氧同位素组成进行分析,研究鄱阳湖湿地苔草在枯水期的水分利用策略.结果发现:土壤水的氢氧稳定同位素比之间有明显的线性相关关系,在水位更低的2016年土壤水经历了更严峻的蒸发,根据氧同位素比和土壤含水率随深度变化可以将土壤水分为表层土壤水 、深层土壤水和地下水三层;在枯水期,苔草对三种水源的利用比例为28.2% ~41.4%,对各水源利用比例总体上大致相当,但断面之间的表现差异明显,各采样点之间有所差别,且在2016年枯水期差别更加明显.%Carex ,the typical plant of Poyang Lake wetland ,was selected to study the water use strategy in December of 2015 and 2016 by field sampling and analyzing on stable hydrogen and oxygen isotopic composition of plant water and soil water .The results showed that there was a significant linear correlation between the hydrogen and oxygen stable isotope ratios of soil water , which experienced more severe evaporation in the dry season of 2016 than in 2015 .The soil water can be divided into three layers including surface soil water ,deep soil water and groundwater according to the distribution of δ18 O and soil moisture with depth .The absorption ratios of Carex to the three layers were among 28 .2% to 41 .4% in the dry season ,indicating a generally roughly equal absorption to surface soil water ,deep soil water and ground water .The ratios were distinct in two sections and were different in sampling points .The differences were more obvious in dry season of 2016 with lower water levels than in 2015 .

    • 摘要: 水位波动对鄱阳湖草滩湿地的形成与分布至关重要,但不同要素对湿地植物种的具体影响不尽相同.本研究以湿地优势植被苔草群落为研究对象,通过环湖区样带设置和植被调查得到较大尺度上的苔草分布数据,以不同水文站水文数据结合湖区DEM插值得出各样点水位波动要素数据:年内最大水位差R,年内淹没出露频次F,年平均水位M,最长淹没的出露日期D,年内总出露时间T,用CART模型进行分析.结果表明:1)影响鄱阳湖区草滩湿地苔草群落分布的最直接的水位波动要素为T和R;2)年内总出露时间大于84天(T≥4.619),年极差水位大于11.3 m(R≥10.41)时,苔草群落的综合分布情况最佳.进一步探讨认为:其他水位波动要素未能被CART模型选为分类依据,可能是因为彼此之间存在相关性;高程决定植被分布,实际上是多种水位波动要素综合影响的结果,精度要求不高时,可以用高程替代水位波动各要素进行简略分析.本研究相关结论可以为鄱阳湖控湖工程今后的运行,提供一定的参考,以维持草滩湿地生态系统的稳定,更好地实现其生态价值.
