The results showed that the growth of Jinguang plum seedlings were remarkably restrained by salt stress. With the increasing of salt concentration, the plant height, leaf area, leaf fresh weight, leaf dry weight, stem dry weight and root dry weight were remarkably decreased, and the chlorophyll content, photosynthesis rate, transpiration rate and stomatic conductance in leaves were declined too, but the intercellular CO2 concentration was inclined.

结果表明盐胁迫抑制了金光杏梅幼苗的生长，随着盐浓度的升高，金光杏梅的株高、叶面积、叶鲜重、叶干重、茎干重、根干重均显著降低；叶片叶绿素含量、净光合速率、蒸腾速率、气孔导度亦显著降低，且盐浓度越高，下降幅度越大；细胞间隙CO2浓度随着盐浓度增加而增大，表明盐胁迫下非气孔因素是导致金光杏梅叶片光合速率下降的主要原因。

Result After soaking seeds with 10, 20, 30, 40 mg/L of triadimefon, the plant height of V. unguiculata seedlings was obviously restrained, the ration of root to shoot was significantly increased and the root length was decreased to different extent.

结果］10、20、30、40 mg/L三唑酮浸种后，豇豆幼苗的株高受到明显抑制，根冠比显著增加，根长有不同程度的降低。

The results revealed that with the increasing ear of continuous C. sativus cropping soil vanillic acid, p-hydroxyhenzoic acid and ferulic acid accumulated gradually. The total amount of the three phenolic compounds reached 29. 8 mgkg^(-1) dry soil after 7 years cropping, being markedly higher than that after 1 or 3 years cropping. After treated with these compounds, the root length and stem width of C.

结果表明：土壤中香草酸、对羟基苯甲酸及阿魏酸随黄瓜连作年限增加而呈现积累趋势；在连作7年的大棚土壤中3种酚酸类物质总量达29.8mgkg^(-1)干土，显著高于连作1年和1年土壤中的含量；酚酸物质可使黄瓜幼苗根长及茎粗显著降低，使株高及干物质量略有下降。

Description: Perennial herbs, 5-20 cm tall, densely white villose; roots slender, terete, up to 40 cm long, fleshy, stem buried in sand with apical part emerged above ground.

The fungus CFCC84965,which was isolated from Meloidogyne hapla eggs in sweet melon roots grown in plastic house in Muping,Shandong province in 2002,was identified as Pochonia suchlasporia var.catenata and it is reported in China for the first time.

分离自山东省牟平市塑料大棚种植的甜瓜根结线虫卵上的菌株CFCC84965，根据培养条件和形态特征鉴定为萨克拉普奇尼亚菌串孢变种Pochonia suchlasporia var.catenata，为中国新记录种。

The more degree shaded treatments were, the more biomass was allocated to the below-ground parts, resulting in the less ratios between above-ground and below-ground biomass. Shaded treatments limited sexual reproductive ability of V. spinulosa, which has reproduced less of ramets and winter tubers under shaded conditions versus natural conditions. V. spinulosa adapted the change of light by means of refuging life-history strategy.

随着遮阳强度的增加，刺苦草的最大叶长、总葡匐茎长和总的叶面积减少，遮蔽强度越大，分配到地下的生物量越多，冠根比率越小；遮阳生境下的刺苦草的有性繁殖受限，无性繁殖形成的分株和冬芽也比自然状态少得多；刺苦草采用回避策略应对光照胁迫。
