The results showed that the overexpression of CBF1 could obviously improve cold tolerance of plant.Compared with non-transformed control plants,the transformed plants had a shorter and stronger stem,more leaves that were bottle-green and thicker,and a longer growth period.

结果表明：CBF1的组成型表达增强了冷敏感植物的抗寒性；在表型上使植株矮壮，叶片着生密集，叶色深绿，叶厚度增加；促进侧枝生长，延长营养生长期，推迟花期；对植株的结实性无明显影响。

该文研究了多重复干旱循环对1年生北美短叶松和黑云杉苗木的气体交换速率及水分利用效率的影响。结果表明，多重复干旱循环对它们的气体交换有显著影响（P＜0.5），而对其水分利用效率影响不大（P＞0.1）。

Result Among the 1st principal components, the positive weight value of chest diameter was greatest and it was the eigenvector with greatest influence on the 1st principal components. Among the 2nd principal components, the character loading value of leaf-lobed width and the positive weight values of angle between leafstalk and its branch and leaf-shape index were greater. Among the 3rd principal components, the positive weight values of leaf number, branch length, branch thickness and developed degree of crown size of 1 year old branches were greater.

结果］在第一主成分中，胸径的权重正值最大，是对第一主成分影响最大的特征向量；在第二主成分中，叶裂宽的特征负荷值较大、叶柄与着生枝夹角和计形指数的权重正值较大；在第三主成分中，一年生枝的叶数、枝长、枝粗和冠幅发达程度的权重正值较大。

The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.

实验部分采用以石油醚脱脂，甲醇为溶剂的回流提取法来提取植物多酚，用显色反应检识酚羟基；采用紫外分光光度法对多酚粗体物进行总多酚含量的测定；选取了聚生小穴壳菌、立枯丝核菌、梨叶点霉等10株常见农林业致病真菌，采用试管液基稀释法对多酚粗提取物进行了抗真菌活性筛选试验，并测定其最低抑菌浓度；采用柱层析法和薄层层析法对其中抑菌效果较好的龙血竭进行分离分析，根据其中3种化合物的光谱数据UV、IR、~(13C-NMR、1H-NMR和MS鉴定其结构。

In this paper, the bio-ecological characteristics of indigenous halophytes: Salsola implicata, Suaeda linifolia, Halocnemum strobilaceum and Kalidium foliatum will be studied in order to explore the mechanisms of plants tolerance and to get the theory and measures for treating salt soil and applying halophytes.

本文拟通过对生长于盐渍化土地上的四种常见盐生植物：盐爪爪、盐节木、亚麻叶碱蓬和密枝猪毛菜的生物生态学特性的研究，查明盐生植物适应盐渍化土壤的机制，为在盐渍化土地上恢复、重建和扩展植被，并为改造该类土地提供依据。

Primary Study on Salt Adaptability of Suaeda linifolia ;2. In this paper, the bio-ecological characteristics of indigenous halophytes: Salsola implicata, Suaeda linifolia , Halocnemum strobilaceum and Kalidium foliatum will be studi.

Leaves. Result: Extraction temperature had effect on total flavonoids yield, and ethanol concentration had more obvious effect than extraction temperature. The more natural storage time, the less total flavonoids content, and the average descent rate was 24.74% per year. The flavonoids content from Lithocarpus polystachyus Rehd. gathered between August and October was the highest. The total flavonoids content was higher in the new leaves of Lithocarpus polystachyus Rehd.

结果：乙醇体积分数对总黄酮提取量有显著影响，提取温度对总黄酮提取量有影响；多穗柯自然存放时间越长，总黄酮含量越低，平均每年下降24.74%；不同季节采摘的多穗柯其总黄酮含量以8~10月最高；经对怀化多穗柯嫩叶和老叶中总黄酮的提取测定表明，多穗柯中嫩叶总黄酮含量最高，二年生最低。

Inflorescence iterauctant, fully bracteate, subtended by a broad 2-keeled prophyll; pseudospikelets rarely solitary, usually several to many clustered to capitate on flowering branches.
