刺槐

Such plants usually have one or more domatia, cavities in stems, leaves or roods that house ants. These may be elaborate systems of cavities with many chambers, e.g. Myrmecodia, or simple hollows in internodes, leaf veins, petioles or stipular spines, e.g. whistling thorns.

这类植物通常都具有一个或多个虫菌穴，虫菌穴是在植株的根、茎、叶上用来容纳蚂蚁的空腔，这些空腔具有许多发达的小室，例如茜草科具有简单而中空的结间部，阿拉比卡咖啡具有含有空腔的叶脉，有的植物叶柄及托叶处也有这样的结构，例如牛角刺槐。

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。

Oneyear old poted Fraxinus velutina and Robinia pseudoacacia seedings were tested by neutral salt and mixed salt solutions.The dynamic changes of a,b and total contents of chlorophyll were studied and the correlation of chlorophyll with MDA and Pro was analysed.

用不同浓度的中性盐和碱性盐(NaCl、NaHCO3、Na2SO4、 Na2CO3)溶液处理1 a生刺槐和绒毛白蜡，研究了两树种叶片中叶绿素a、叶绿素b和总叶绿素含量的动态变化以及叶绿素和丙二醛、脯氨酸的相关性。

MethodThe qualitative analysis to the acetone extractives of silver chain wood before and after discoloring was carried on showing the main components of the acetone extractives and then taking comparison.

方法］通过对刺槐木材变色前后丙酮抽出物的定性分析，得出变色前后丙酮抽出物的主要成分，进行对比分析，初步得出抽出物对诱发变色的作用。

The results showed that mixed forest improved sandy soil water-physical properties, that is, increased soil maximum moisture capacity, capillary capacity and field capacity.

结果表明，刺槐与杨树混交后，土壤水分-物理性质得到了改善，表现在土壤最大持水量增加，毛管持水量、田间持水量得以提高，土壤有效持水量也有了较大幅度的提高。

An irresistible fascination took possession of her; she tried to turn away her eyes from the leaflets which were trembling in her hand, she gazed at the sky, the street, the acacias all bathed in light, the pigeons fluttering over a neighboring roof, and then her glance suddenly fell upon the manuscript, and she said to herself that she must know what it contained.

一种无可抗拒的诱感力把她控制住了。她想把她的眼睛从那几张在她手里发抖的纸上移开。她望望天，望望街上，望望那些沐浴在阳光中的刺槐，在邻居屋顶上飞翔的鸽子，随后她的视线迅捷地朝下看那手稿，并对自己说，她应当知道那里写的究竟是什么。

Base on MS medium, four kinds of auxin IAA,IBA,NAA,2,4 D and three kinds of cytokinin BA,KT,ZT were arranged in monofactoral experiments. NAA and BA were selected to be the best regulators for regeneration of folioles and raches of the compound leaf.

以MS为基本培养基，对IAA、IBA、NAA、2 ，4 D 4种生长素，及BA、KT、ZT 3种细胞分裂素进行单因子试验，对比并筛选出对刺槐小叶和叶轴再生最好的生长素和细胞分裂素为NAA、BA。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
