以江苏地区3个细柱五加居群(汤山、宝华山、铁山寺)为材料,分别观察叶片形态结构,测定叶绿素含量及光合特性,为细柱五加人工栽培提供技术依据。结果表明,3个居群叶片结构均具阴生植物特征;光补偿点分别为24、18和21μmol.m-2.s-1,光饱和点分别为555、309和348μmol.m-2.s-1;CO2补偿点分别为72.5、82.5和67.6μmol.mol-1,CO2饱和点分别为1 500、2 550和1 490μmol.mol-1;叶绿素a/b均较低。认为3个居群细柱五加均为阴生植物,人工栽培需遮阴处理。
In order to provide technical basis for the artificial cultivation of Scutellaria barbata, the three small spermatophyte groups (Tangshan, Baohuashan and Tieshan Temple) in Jiangsu Province were used as materials to observe the morphological and morphological structure of the leaves, determine the chlorophyll content and photosynthetic characteristics. The results showed that all the three populations had shade-shade characteristics. The light compensation points were 24, 18 and 21 μmol.m-2.s-1, respectively. The light saturation points were 555, 309 and 348 μmol.m-2, respectively. s-1. The CO2 compensation points were 72.5, 82.5 and 67.6 μmol.mol-1, respectively. The CO2 saturation points were 1 500, 2 550 and 1 490 μmol.mol-1, respectively. That the three populations of fine columns plus five are shade plants, artificial shade to be dealt with.
