对新铁炮百合(Lilumformolongi)的9个基因型的叶片抗热性形态指标进行了探讨。结果表明:抗热性较强的基因型有较大的下角质层厚度、栅栏组织厚度、海绵组织厚度、栅栏组织/海绵组织比值、叶片厚度,这5项指标可用于测定新铁炮百合的抗热... 对新铁炮百合(Lilumformolongi)的9个基因型的叶片抗热性形态指标进行了探讨。结果表明:抗热性较强的基因型有较大的下角质层厚度、栅栏组织厚度、海绵组织厚度、栅栏组织/海绵组织比值、叶片厚度,这5项指标可用于测定新铁炮百合的抗热性;9个基因型的抗热性强弱顺序为:M>M2 8>O2 10>O2 28>O1 13>M2 9>O ovum>O>M1 10。 展开更多

Based on the anatomical study of leaf cuticles of Cordaites from the Lower Permian Shanxi Formation in Baode of Shanxi, the author analysed the epidermal characters of Cordaites in this area. On the base of the abundant compressions and laboratory studies, the author complemented some new data of the cuticular characters of the speeies Cordaites baodeensis Sun for its study of taxonomy. Meanwhile, the author newly discovered a number of sporopollen fossils associated with the mega-plants of Cordctitales, described 9 species of 6 genera. The palynological data can provide a supplement evidence for defining the age of C. baodeensis and its associated plants to be Early Permian. 展开更多
