The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。

The results showed that some characters, such as shape of leaves and tooth number of leaf-margins, were not taxonomically reliant characters since they varied greatly within the same group; while the characters, such as hairs on leaves, venation of leaves, length and color of flowers or inflorescences, and length of fruits, were good characters for the classification of Stachyurus as they are usually stable.

结果表明：叶片形状、叶缘齿、花序下的叶片是否宿存以及花序是否具花序梗等性状在种间变异非常大，单个性状对旌节花属属下分类意义不大；而叶片毛被、脉序和结构，花序长度，花的大小和颜色以及果实大小等性状通常较稳定，可作为旌节花属划分种和变种的重要依据。

Leaves began to shape from the end of March until September, and the growth of young leaves terminated in November. In February or March of the next year, the leaves shot out of the ground. Finally, they withered in May. In addition, 4 phases exist in the process of leaf shaping (buttress forming, primordium, straplike leaf and sheath). At first, the leaf primordium shapes the zonary leaf, and then the plaits are formed at the bilateral base of the zonary leaf. Finally, the plaits close and form sheaths.

结果发现：中国石蒜的叶片在3月底开始分化，9月分化结束，11月，幼叶生长停止，并於翌年2、3月露出地面，5月即枯萎，完成生活史；叶片的形成经历4个阶段，即叶原座形成时期、叶原基生长时期、带状叶片的形成以及叶鞘的形成时期；叶原基先形成带状叶片，随后在其基部两侧形成褶，进而闭合发育成叶鞘。

The results indicated that the growth of 3-year-old Prunus salicina was significantly higher than that of the other species, such as 139.1% and 153.7% higher than Toona sinensis and Juglans regia in height growth, respectively. The maximum percentage of DBH more than 1.0 cm was 91.9% for P. salicina. Next were 49.5% and 48.8% for Ulmus pumila and Pteroceltis tatarinowii, respectively. The contents of total N, total P and total K ranged from 1.36% to 2.52% in the leaves of testing species. The highest content of total N and total P was found in the leaves of Catalpa bungei, while the highest content of total K was observed in P. saltcina leaves. The results indicated that P. salicina, P. tatarinowii, U. pumila had well adaptability on the Karst area both in the growth status and the improvement to the soil with the fallen leaf.

结果表明：(1)3年生冰脆李的生长量明显优于其他树种，其高生长比香椿、核桃分别大139.1%和153.7%；植株胸径大于等于1.0 cm株数的百分比以冰脆李最高达到91.9%，其次是榆树和青檀，分别是49.5%和48.8%；(2)8个树种落叶的全N、全P和全K的总含量变动为1.36%~2.52%，其中全N、全P含量以滇楸最高，全K含量以冰脆李最大；(3)从各树种落叶前后各元素含量及其转移情况看，冰脆李、青檀表现出对大部分营养元素具有较高的循环利用养分或保持养分的能力，而香椿及刺槐相对较弱。

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.

GUS组织化学染色结果表明，在MPBQ MT启动子驱动下，报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达，且在茎、叶、种荚中表达量较高，而在根、花瓣和种子中则没有观察到GUS基因的表达，表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
