Abstract

Pollen of oaks and rosaceous taxa from a little researched part of the world, southwestern Sichuan, China, have been examined. Light microscopy photographs and statistical measurements are presented for deciduous oaks, evergreen oaks, and rosaceous taxa morphologically similar to oak species. The results show that with careful examination of pollen size, sculpture and aperture type, deciduous oaks, evergreen oaks and rosaceous taxa of southwestern Sichuan Province can be reliably separated using light microscopy. The usefulness of this study is not limited to southwestern China but has applications for those working in similar environments where the length of the wet season affects the percentages of deciduous and evergreen oaks in the vegetation.

    Other authors (e.g. Sun et al., 1986; Dai et al., 2018) have distinguished Cyclobalanops from other oaks (Quercus) but we included it with the non-deciduous (evergreen) oak group (Liu et al., 2007). The evergreen oaks have a distinct poroidal thinning along the colpus that is frequently torn, often have an equatorial bulge and their tectum sculpture is fine and angular (Jarvis et al., 1992). Pollen, spore and algal types and their environmental groupings are listed in the supplementary data.

    Liu et al. (2016), following modern pollen studies of ‘paddy’ field Poaceae pollen (Yang et al., 2012), suggest that grass grains above 40 μm may indicate well-managed rice cultivation. Quercus pollen grains have been separated into those of evergreen oaks (Cyclobalanopsis) and of deciduous oaks, (including genera with very similar pollen grains and so combined into a composite curve Quercus/Lepidobalanus), using published keys and photographs (Chang and Wang, 1986; Jarvis et al., 1992). Composite curves are also employed for other genera with pollen that is very difficult to separate with certainty: Ulmus/Zelkova, Corylus/Ostrya, Castanopsis/Lithocarpus and Typha/Sparganium, where Typha is T. angustifolia.

    In the TPRR, Quercus franchetii from the savanna adapts to the dry-hot climate at low elevations, Q. aquifolioides preferring the alpine environment is common in the Abies forests and Q. pannosa, Q. senescens are distributed in the coniferous and broadleaved mixed forest. However, their pollen is not possible to differentiate (Jarvis et al., 1992). By comparison, Quercus pollen is quite characteristic for the mixed forests on the Yulong Mountain (Xiao et al., 2009) where the savanna and alpine Quercus forests are rarely developed.

    Pollen was initially extracted from sediment samples spaced at 8 cm intervals, following standard techniques described in Faegri and Iversen (1981) and Moore et al. (1991). Pollen identification was undertaken with reference to Chinese and southeast Asian pollen guides (e.g. Institute of Botany and South China Institute of Botany, 1982; Jarvis et al., 1992; Wang et al., 1995; Qiao, 2004; Wang and Pu, 2004; Fujiki et al., 2005; Menitsky, 2005; E-Floras, 2006) and with assistance from Professor Tong, Department of Hydrology and Environmental Geology, Chinese Academy of Geological Science (CAS), Shijiazhuang. The pollen sum (including trees, shrubs, herbs, grasses and sedge) was comprised of a count of 300 pollen grains per sample.
