positive spike

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。

Root dry Wt and fresh Wt were positive related to the yield and spike number.

根干重、根鲜重与籽粒产量、单位面积穗数呈正相关，前期与千粒重及穗粒数呈负相关，后期呈正相关。

Depending on the polarity of an ESD event you apply to the circuit's input connector, its high-voltage spike discharges through diode D1A or D1B into the positive or the negative power-supply rail.

依靠ESD适用电路输入连接器的极性，其高电压放电通过二极管D1A或D1B进入供电正向或负向电源。

The positive correlation between 1000-grain weight and grain numbers per spike, plant height and protein content, heading date and spikelet number per spike, have disadvantageous effect on the genetic improvement of wheat-rye recombinant lines.

千粒重和穗粒数的负偏相关对小麦异源（黑麦）重组系的遗传改良有重大影响，打破该相关也相当困难。
