摘要:
为分析不同产地半夏在同一试验地的农艺性状及光合生理特性差异,以2年生20个不同产地的半夏为试验材料,测定其农艺性状、光合生理指标及叶绿素荧光参数。结果表明,不同产地半夏在农艺性状上存在显著差异,其中,陕西商洛产半夏的植株最高、种球最大;贵州贵阳产半夏的叶面积最大;河北保定产半夏的农艺性状整体较低。不同产地半夏的光合参数也存在明显差异,推测其光合特性和光能利用率具有较大差别,四川和贵州产半夏具有较高光合潜力。相关性分析发现,净光合速率(net photosynthetic rate,Pn)与气孔导度(stomatal conductance,Gs)、水分利用率(water use rate,WUE)、最大荧光(maximal fluorescence,Fm)、电子传递速率(electron transport rate,ETR)和叶绿素a(chlorophyll a)含量呈极显著(P<0.01)正相关,与叶绿素b(chlorophyll b)含量呈显著(P<0.05)正相关。主成分分析发现,种球直径、中裂叶长、株高、蒸腾速率(transpiration rate,Tr)、光化学淬灭系数(photochemical quenching,qP)和胞间CO2浓度(intercellular CO2 concentration,Ci)是影响半夏生长的主要指标。聚类分析发现,四川、贵州、甘肃、河南、湖南和陕西等产地的半夏农艺性状表现较好,且具有较强的光合潜力,被聚为第Ⅰ类;保定、邢台、张家口和文山等产半夏的各项指标较低,被聚为第Ⅱ类。综上所述,四川、贵州、甘肃、河南、湖南和陕西的半夏种源具有明显优势,有良好的培育前景。以上研究结果为半夏良种选育提供了理论依据。
