TLDR
In this article, a hand-held method for thin wood slicing was proposed to improve the efficiency and quality of making thin slices using tools from tool making, material treating and operation methods.Abstract:
Preparing wood slices is a vital process in identifying wood species though micro-thin slicing To improve the efficiency and quality of making thin slices, the author found a new hand-held method for slicing This article describes the method from tool making, material treating and operation methods Compared with the routine slicing method, it was found that this new method was more suitable for rare and high-grade wood, or for the cases that have strict requirements for time and efficiencyread more

TL;DR: Genetic analyses indicate that Pinus densata is a natural homoploid hybrid originating from Pinus tabuliformis and Pinus yunnanensis, and needle morphological and anatomical features show relative species stability and can be used to identify coniferous species, which helps to better understand of the hybridization roles in adaptation and speciation in plants.

Genetic structure of needle morphological and anatomical traits of Pinus yunnanensis
TL;DR: Variations in needle traits among the populations have shown systematic microevolution in terms of geographic impact on P. yunnanensis, which would be helpful for management of genetic resources and reasonable utilization of them in future.

Environmental contribution to needle variation among natural populations of Pinus tabuliformis
TL;DR: Geographic variation patterns and systematic relation of needle traits differed between the two sampling strategies, suggesting that in situ sampling results may reflect environmental effects and deviate statistical parameters for genetic study.

Genetic Analysis of Needle Morphological and Anatomical Traits among Nature Populations of Pinus Tabuliformis
TL;DR: Variations in needle traits among the populations have shown systematic microevolution in terms of geographic impact on P. tabuliformis, and differences among populations were mainly dependent on needle width, stomatal density, section areas of vascular bundle, total resin canals, and mesophyll, as well as area ratio traits.
