脓疮草复合体的生物学特性研究

通过野外和移栽实验观测，对脓疮草复合体（Ｐａｎｚｅｒｉａｎ ｌａｎａｔａ ｃｏｍｐｌｅｘ）居群进行了生物学特性研究。结果表明：浓疮草复合体居群在生活史方面无明显差异，移栽的１０个复合体居群生活史十分 相似：脓疮草复合本的花量大，花期可达３个月左右，花为雌雄异熟，以异花授粉为主，自交（同株异花授粉）亲合；叶裂程度、花萼裂片宽窄等性状，在天然居群中是连续变化的，而且移栽后可逆性较大，性状不稳定。

Study on biological feature of Panzerina lanata J.Sojak complex

Panzerina lanata (L.) Sojak complex,belonging to Panzerina Sojak (Labiatae).Ten populations were studied on transplantation experiment and field observation for the biological feature of this complex.The results are as follows:there are little difference among life histories of 10 populations,and their life histories are very similar.Because there are generally a large number of flowers in one individual,flowering of single florescence can last nearly three months.All examined populations are protandrous and almost out pollinated,but it leads to a slightly lower seed production when they are self compatible and self pollinated.Some characters which were used to differentiate taxa of the complex,for example the degree of leaf division,the morphology of calyx and so on,are continuously variable in a wide range in wild populations,and there exists considerable plasticity in these characters in experiment field.
