三种苦苣苔对石灰土和红壤的适应性分析
Adaptation of three species of Gesneriaceae in limestone soil and red soil
摘要
Abstract
To explore the adaptation of plants of Gesneriaceae on high calcium and lava environment, Primulina lutea, P. purpurea and Paraboea guilinensis, three kinds of plants of Gesneriaceae were cultivated in limestone soil and redsoil. Morphological characters of these plants were discussed, the chemical elemental contents of plant leaves were tested and compared in two soils. At the same time, the leaves and soil were collected in the sampling sites, and the leaf ele-ments and soil elements were measured as a reference of nursery test. The results showed that the growth and adaptability of three species of Gesneriaceae had differences in two kinds of soils. They grew well in the limestone soil, but not well in red soil. Except for N, the other elements in leaves of Paraboea guilinensis such as P, K, Mn, Mg, Ca, Zn and Cu had extremely significant differences(P<0.01). Except for P, the other elements in leaves of Primulina purpurea such as N, K, Mn, Mg, Ca, Zn and Cu had extremely significant differences in these two kinds of soils(P<0.01). Except for N, Cu, Ca, the other elements in leaves of P. lutea such as P, K, Mn, Mg, Zn had extremely significant differences in these two kinds of soils ( P<0.01) . Except that some of the leaf element ratios had no difference, most of the leaf ele-ment ratios of these three species had extremely significant differences in these two kinds of soils. The correlation analysis of leaf element and cultivated soil element showed that the content of leaf element, like Mn, was positively correlated with the contents of elements in soil such as N, Ca, Mg, Zn, Mn and organic matter. The soil element content, like P, was positively correlated with the content of leaf element such as N, P, and it was negatively related with leaf element like Zn. In the same cultivated conditions, soil and genetic factors were the main causes of different adapations of P. lut-ea, P. purpurea and Paraboea guilinensis.关键词
