根条件

Under the field conditions, the effects of the physical regulation measures such as sheltering by plastic, cutting root on potassium uptake and redistribution in sink and source in tobacco were studied.

在大田生产条件下，采用单株挂牌设置处理的研究方法，研究了覆膜、断根等物理调控措施对烤烟钾吸收及其在库和源中的再分配。

The results showed that root cutting and potassium application could increase the chlorophyll content of leaves in upper and middle stalk positions, which resulted in larger leaf area and more dry matter accumulation in the leaves.

结果表明：在不同施氮量条件下，打顶时断根追钾促进了烟株中、上部烟叶叶面积的扩展和叶质重的增加，其叶绿素含量尽管高于对照，但没有影响到烟叶的落黄和成熟。

A diffusion experiment and pot trial were conducted to evaluate the effect of acidic rhizosphere fertilizer on the soil pH and Fe availability and the growth, iron deficiency correction of peanut on calcareous soil.

在无植物栽培的条件下通过肥料在土壤中的扩散试验研究酸性根际肥对石灰性土壤 pH值、有效铁含量的影响，利用盆栽试验验证对石灰性土壤上花生缺铁失绿黄化症的矫正效果。

Acquisition of nutrient and water by VA mycorrhizae under water stress and application different P lever were studied by soil culture experiment.

采用土培试验，研究水分胁迫条件下，施磷肥接种VA菌根菌对白三叶的生长，养分吸收和水分利用的影响。

VA mycorrhizae could enhance plant dry weight and improve plant P concentration, as well as increase the resistance to drought and water utilization efficiency under water stress and normal water supply at the same P application level.

在水分胁迫和正常供水条件下，施磷量相同，接种菌根组的地上和根系生物量干重显著高於不接种组，干物质累积增加，减轻水分胁迫对植株生长的抑制程度，改善了植株体内磷素养分状况，提高了白三叶对土壤磷的有效利用及水分利用率。

The experiments thus demonstrated some general influences of arbuscular mycorrhizae in the balance of plant mineral nutrition and alleviation of heavy metal toxicity, also the clear variation in fungal adaptation to soil contamination and affinity to host plants, and indicated the possibility of screening of fungal strains for specific application purposes.

试验结果证实了重金属污染条件下丛枝菌根平衡宿主植物矿质营养和减轻重金属毒害的普遍积极作用，同时表明不同真菌菌株对宿主植物适合性及对土壤适应性存在明显变异，显示了适应于不同应用目的筛选适用菌株的可能性。

One QTL for SRLD was detected on chromosome 12 with about 12%variation, and two QTLs for SRLD were detected on chromsome 2 and 11, and about 13.37% and 18.23% of total phenotypic variation were explained.

这与以前的报道所得到种子根长相关的 QTLs 所在位点不一致，这种不一致性可能是由于不同遗传材料及不同实验条件的差异所致，也可能是因为表型测定时期不同所致。

Pepper, curry, chilly peppers, or horse radish cravings may be a sign of pulmonary conditions because hot spices activate blood circulation.

辣椒，咖喱，辣椒辣椒，或辣根的渴望可能是一个标志性的条件，因为热香料激活血液循环。

Methods Explore the optimal concentration of phurbol-12-myristate-acetate and calcium ionophore (A23817) inducing time, and optimal concentration of biotinyl sheep anti mouce IgG (bio-SAM-IgG) and horse radish peroxidasestreptavidin. The CD4(superscript +) cell enriched from peripheral blood mononuclear cells using solid phase anti-CDs monoclonal antibodies were induced by PMA and A23817 under influence of monensin and harvested in vary hours.

从健康人外周血单个核细胞中富集CD4细胞，加入莫能霉素，用不同浓度的佛波醇酯和钙离子载体(A23817)诱导CD4细胞不同时间，比较其胞内表达白细胞介素－2(IL-2)/白细胞介素－4(IL-4)的细胞百分率，确定最适诱生条件；用不同稀释度的IL-2McAb、IL-4McAb、不同浓度的生物素化羊抗鼠IgG(bio-SAM IgG)和辣根过氧化物酶标记的链霉亲和素作棋盘配比试验，确认McAb、bio-SAM IgG和HRP-SA的最适浓度，根据上述结果建立了检测细胞内细胞因子的BSA-ICC法。

There were more isozyme bands in rhizome and leaf than in other org a ns,and zymogram pattern feature of leaf were appearing clearly.In different cult ure types,the change trend of different organs at different periods was the same .

根状茎和羽叶显示的谱带数比其它器官多，且羽叶谱带特征明显，这种差异在不同栽培条件下是相同的。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
