双语例句
- Direct effect or indirect negative effects-of spike's length, nonbearing tillering number and plant height on grain weight per plant are considerably small.
穗长、株蘖数和株高对株粒重直接影响和间接负影响很小。 - Negative selection force is also probably operating on spike protein gene.
这种负选择的力量可能也作用于Spike基因。 - The flag leaf length, width, area and mean awn length per spike were found to be significant positive correlation with grain weight per spike, the blade angle and bend degree of flag leaf to be significant negative correlation with grain weight per spike;
旗叶长、旗叶宽、旗叶面积、穗平均芒长均与穗粒重呈显著正相关；旗叶开张角、披垂度与穗粒重呈显著负相关。 - There was a significant negative correlation between leaf nitrogen content during panicle initiation period and spike rate, which was one of the reasons that led to the low spike rate in FFP treatment.
水稻幼穗分化期叶片含氮量与穗粒数呈正相关关系（P0.01），与成穗率呈显著负相关，这可能是导致农民习惯施肥成穗率低的原因之一。 - Path coefficient analysis at the genetic level indicated that the negative direct effect of the kernel weight on the grain yield was large while the direct effect of the number of kernels per spike was intermediate.
对遗传相关进一步进行通径系数分析表明，每穗粒数对单株生产力的直接作用是正向的，而有效穗数和千粒重对单株生产力的直接作用是负向的。 - Results 1.The drug binding activity of the GABA receptor was decreased and the equilibrium dissociation constant ( K-d) was significantly increased compared with the negative control group 2 hr after irradiation, and a spike value appeared at 24 hr.
结果辐射可显著降低神经细胞中GABA受体生物结合活性，表现为GABA受体蛋白平衡解离常数（Kd）升高，结合活性降低。 - The nitrogen application amount had a positive linearity correlation with spike number while a quadratic curve or negative linearity correlation was existed between the ratio of basic to topdressing and spike number.
施氮量与单位面积穗数呈线性正相关，氮肥基追比与穗数呈二次曲线或线性负相关，专用小麦不同追施氮肥时期处理均三叶一心期追施氮肥穗数最多。 - The results showed that the spike position height coefficient has positive relevance with spike length, grains per row, 1000 grains weight and yield and negative relevance with rows per spike and spike diameter.
结果表明，穗高系数与穗长、行粒数、千粒重、产量呈正相关，与穗行数、穗粗呈负相关。
