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。

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。

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.
