引言众所周知,低温会抑制甘蔗花粉的形成。因此,位于夜温15℃或15℃以下的亚热带甘蔗育种场被迫在花粉形成和杂交期间,把大部分亲本的开花茎放到加热的温室中,以保证花粉充分的散发。
It is well known that hypothermia inhibits sugarcane pollen formation. As a result, subtropical sugarcane breeding farms located at night temperatures of 15 ° C or below are forced to place most of the parent flowering stems in a heated greenhouse during pollen formation and crossing to ensure adequate pollen shedding.
