1. A new variety of Quercus variabilis Bl.

2. Quercus variabilis is one of the primary sources of industrial cork in China.

3. Quercus variabilis is an important tree species for afforestation, which have great economic value.

4. The study showed that the Quercus variabilis communities in different habitats significantly differentiated in their trait parameters.

5. Determinations of a 45 years old natural secondary Quercus variabilis forest in Baotianman Natural Reserve in Neixiang County, He nan Province show that its biomass was 167.

6. The distribution patterns of Quercus variabilis population have close relation with spatial measurement yardsticks.

7. Quercus variabilis is widely distributed in more than 20 provinces and regions in North, Northwest, Central, South, Southwest of China.

8. Time series model can simulate and predict the increase of Quercus variabilis population by the difference, periodic method.

9. The variations of cork characters from 10 populations of ? Quercus variabilis ? in Shaanxi province are analyzed.

10. Histological Observation of Somatic Embryogenesis from Cultured Embryos of Quercus variabilis BI.

11. By using sequential fumigation-incubation method, the soil labile carbon in a secondary Quercus variabilis forest and a Pinus taeda plantation in hilly area of South Jiangsu, China was investigated.

12. Changes in plant species diversity in a restoration sequence of Quercus variabilis forest stands in Bao Tianman mountain were studied.

12. try its best to gather and create good sentences.

13. Both the sap flow velocity of Pinus tabulaeformis and Quercus variabilis had very close linear relationships with the soil moisture and soil water potential on a monthly average basis.

14. The 52 dominant species is divided into two groups:(1) Quercus variabilis ecological species group and (2) Crataegus maximowiczii ecological species group.

15. And determine the dominant species that all the levels of Quercus variabilis forest plant functional groups need to measure.

16. This paper analyzed the niche breadth and overlap of the main population of Quercus variabilis forest in Henan Province.
