中国科学院昆明植物研究所高山植物多样性适应与进化研究组与瑞士巴塞尔大学高山植物进化生物学研究组合作，依托迪庆白马雪山高山冰缘生态系统云南省野外科学观测研究站，对白马雪山海拔4270米处树线交错区内黄背栎（Quercus pannosa）海拔分布上限的形成原因进行了探索。研究发现，黄背栎（Q. pannosa）越冬叶片和叶芽的冬季低温耐受值分别为-32.6 °C和-27.1 °C，是目前已知的耐受低...
Biomass allocation of chestnut oak (Quercus castaneifolia C.A. Mey) seedlings: effects of provenance and light gradient
leaf to root ratio Hyrcanian forest adaptation
2015/5/5
Patterns of biomass allocation were determined for seedlings of five provenances of Quercus castaneifolia from west to east of the Hyrcanian forest along a rainfall gradient. Experimental design was e...
Seasonal variation of isoprene basal emission in mature Quercus crispula trees under experimental warming of roots and branches
isoprene biogenic volatile emission Quercus crispula experimental warming
2017/4/11
Isoprene is a reactive volatile organic compound (VOC), the annual global biogenic emissions of which are the largest
of the non-methane VOC. Since isoprene emissions are partly temperature-driven, u...
Diurnal variations of polar organic tracers in summer forest aerosols: A case study of a Quercus and Picea mixed forest in Hokkaido, Japan
secondary organic aerosol isoprene 2-methyltetrols levoglucosan
2017/4/12
We investigated the summertime formation of secondary organic aerosols (SOA) via the oxidation of isoprene, α/β-
pinene and β-caryophyllene in a Quercus crispula and Picea glehnii mast mixed forest l...

Drought reduced monoterpene emissions from the evergreen Mediterranean oak Quercus ilex: results from a throughfall displacement experiment
monoterpene emissions evergreen Mediterranean oak Quercus ilex displacement experiment
2010/1/20
The effects of water limitations on the emission of biogenic volatile organic compounds are not well understood. Experimental approaches studying drought effects in natural conditions are still missin...
Transpiration of montane Pinus sylvestris L. and Quercus pubescens Willd. forest stands measured with sap flow sensors in NE Spain

栓皮栎天然群体SSR遗传多样性研究Genetic Diversity of Microsatellites（SSRs）of Natural Populations of Quercus variabilis
栓皮栎 微卫星(SSR) 遗传多样性 遗传分化
2008/1/8
摘要
利用微卫星(SSR)标记对我国4个省内的5个栓皮栎（Quercus variabilis Bl.）天然群体的遗传多样性进行了研究。16对SSR标记揭示了栓皮栎丰富的遗传多样性：等位基因数（A）平均8.4375个，有效等位基因数(Ne)平均为5.9512个，平均期望杂合度(He)0.8059，Nei多样性指数(h)为0.8041。栓皮栎自然分布区中心地带的群体具有较高的遗传多样性，而人为对森...
