查询词典 controlled pollination

When there was only one pollen donor, gene flow frequency was in direct proportion to the pollen density.(8) The strong pollen competition from self-pollination might contribute to the very low outcrossing rates and gene flow frequencies in rice varieties.(9) The study of rice pollen flow showed that with the artificial disturbance of pollen dispersal there were pollen grains detected at 90 m from the pollen sources.

9对水稻花粉流的研究显示，在赶粉的实验条件下，于远离花粉源的90 m处仍然检测到花粉分布，回归分析显示水稻的花粉可以传播100 m以上，甚至在远离花粉源的200 m的距离处仍然可能有花粉分布，这表明水稻的花粉可以传播非常远的距离。

Other types of variated flowers besides A type because of small amount and simple structure or late-maturing, there was no significant effect on fig wasps' pollination, oviposition and development and maturation of syconia.

除A型外的其他类型的变异花由于数量少且结构简单，或发育后熟，对传粉小蜂传粉、产卵以及花序的发育与成熟没有显著的影响。

The result showed that pericarp thickness was significantly different among different varieties and among different days after pollination.

结果表明，不同品种和不同授粉天数的果皮厚度差异明显；同一品种籽粒内不同部位间的果皮厚度也有较大差异，这种差异在灌浆前期更为明显，主要表现为胚背面的果皮较胚面薄，之后这种差异逐渐缩小。

But it says there were enough honey bees to provide all the agricultural pollination needed last year.

但是它说，那里有足够的蜜蜂提供去年所需的所有的农业授粉。

But it says there were enough honey bees to provide all the agriculture pollination needed last year.

但是，它说去年有足够的蜜蜂来为所有的有需要的农作物授粉。

Therefore, the spiral arrangement is not likely to be the result of a direct adaptation to wind pollination.

因此，这种螺旋形安排不太可能是对风授粉的一种直接适应所带来的结果。

If you are pollinating more than one species, and do not want to do any cross pollination, then it is

如果你想在不同的种类间进行杂交，又不想受到其他品种的干扰
