Abstract

Abstract

The heterogeneous habitat plays an important role in conservation and restoration of rare and endangered plants. In karst areas, the common exposed stone teeth can cause the differentiation of soil physical and chemical properties, thus affecting the distribution and adaptation characteristics of rare and endangered plant populations. To examine the distribution and adaptation characteristics of endangered plants in heterogeneous habitat, we investigated the leaf phenotypic variation and the distance between plant and stone teeth of Loropetalum subcordatum population by the transect method in the Maolan National Nature Reserve, Libo county, China. We divided the distance into three groups (0 cm, 0.1-10 cm, and above 10 cm) for analysis. The results show that， (1) among 515 individual of Loropetalum subcordatum investigated, 388 pieces (75.3%) have DBH≥1 cm. The maximum DBH is 17.5 cm, and the distance between it and the stone teeth is 7 cm. In the 0 cm distance group, there are 89 DBH≥1 cm individuals with average 3.44±2.26 cm, and seedlings and saplings are present in 19 individuals. In the 0-10 cm distance group, 21 pieces have DBH≥1cm with average 4.38±4.55 cm, and seedlings and saplings are 62 individuals. In the above 10 cm distance group, there were 278 DBH≥1cm individuals with average 3.93±2.75 cm, and seedlings and saplings are 46 individuals. (2) The length of Loropetalum subcordatum population’s leaf is 106.60±19.28 mm, and the width is 47.53±10.10 mm, the ratio of width to length is 0.45±0.08, the thickness is 0.32±0.05 mm, respectively. The petiole length of Loropetalum subcordatum population is 12.82±3.35 mm and diameter is 1.43±0.35 mm, respectively. There are no significant differences in the length, width, and petiole diameter of Loropetalum subcordatum leaf in the distance groups 0 cm, 0.1-10 cm and ≥10 cm, but the leaf thickness, petiole length and leaf width/length are significantly different(P＜0.01). On the whole, the stone teeth has a profound influence on the distribution and leaf characteristics of Loropetalum subcordatum.
