银杏为第四纪冰川后的孑遗珍贵树种，可能是地球上现存种子植物中最古老的一种，具有重要的经济价值、学术研究价值和园林观赏价值。

Proved by experiments, the ginkgo pyroligneous liquor has great promoting function on the seed germination of crops and the growth of seedling.

经试验证明银杏木醋液对作物种子的发芽和幼苗生长有很大的促进作用。

The method for preparing the ginkgo pyroligneous liquor of the invention is simple, the obtained product is a green product of all-natural formulation and has no residue and pollution as a natural agricultural chemical substitute.

Thus it is presented an effective RNA extraction method based on the nuclease adsorbent macaloid, poly vinyl pyrrolidone, and high concentration of KAc and ethylene glycol monobutyl ether, which has successfully extracted high-quality RNA from many materials difficult to RNA isolation, such as RNase-rich rabbit liver, plant and microbial tissues rich in polysaccharides, lipids and polyphenol compounds.

现利用硅藻土对RNase的吸附性，结合PVP、高盐及乙二醇丁醚沉淀等处理，建立了一种广泛适用的RNA提取方法。在富含多糖的玉米胚乳，富含RNase的动物肝脏，多酚多油脂的银杏、麻疯树以及木霉、酵母等10多种RNA提取困难的动、植物与微生物材料中都提取出完整性好，得率高的RNA。

Ginkgo is lofty and much more ramose arbor.

银杏为高大而多分枝的乔木。

Methods: The model was constructed by ethanol administration orally in mice. Salisburia adiantifolia preparation was administered as antioxidant to protect the gastric mucosa.

大鼠用乙醇灌胃造模，给予抗氧化剂银杏制剂预防胃粘膜损伤，测定胃粘膜和血中的脂质过氧化物含量。

In order to better understand the determinants of tree height limit,32 tall tree species such as Parashorea chinensis,Sapium baccatum,Garcinia cowa,Eucalyptus citriodora,E.grandis×E.urophylla,Albizia falcataria,Populus tomentosa,Platanus hispanica,Ginkgo biloba,Pinus tabulaeformis,Ulmus pumia,Salix gordeivii,and Elaeagnus angustifolia from typical environments such as Xishuangbanna rainforest,Guangzhou subtropical area,Zhengzhou,Beijing,Helanshan mountain and Maowusu sandland in China were studied.

为了更好地了解树高极限的限制因素，本文对全国典型水分分布区域西双版纳、广州、郑州、北京、贺兰山和毛乌素沙地等地区生长的望天树、浆果乌桕、小叶藤黄、柠檬桉、巨尾桉、南洋楹、毛白杨、悬铃木、银杏、油松、榆树、沙枣、小黄柳等32种较高的木本植物进行了研究。

Objective To study the effect of Ginkgo biloba extract on serological indexes as well as its role in lipid metabolism of diabetic rats.

目的 究银杏叶提取物对糖尿病大鼠血清学指标的影响，探讨其在糖尿病大鼠脂代谢过程中的作用。

The content of flavanone and lactone in leaf and the leaf output were studied by randomizing block arrangement of 31 gingko female varieties and 4 staminiferous plant type single clone.

采用31个银杏雌性品种和4个雄株类型的单株无性系，随机区组排列，对叶产量性状及其与叶产量的相关性，叶黄酮、内酯含量进行了研究。

The leaf area, single leaf fresh weight, flavone content and lactone content in good variety were 2.04, 2.71, 2.05 and 2.17 times of those in common variety respectively. There were no obvious difference between the female and staminiferous plants in leaf output character, flavone content and lactone content, which proved that there were hereditary change among the gingko variety in leaf output character, flavone content and lactune content.

较好品种的叶面积、叶重、叶黄酮、内酯含量分别是较弱品种的2.04、2.71、2.05和2.17倍；雌雄株间叶产量性状、黄酮含量、内酯含量无差异，证明银杏品种或类型间叶产量性状、黄酮、内酯含量均存在遗传变异，这种变异与雌雄株无关。
