第二光周期反应属一对主效隐性基因控制。
The second photoperiodic reaction is controlled by a recessive gene.
它们对日长也无严格要求，其光周期反应不具有长日植物的性质。
They are insensitive to temperature in growing process and no response to low temperature in early phase of growth. These cultivars are insensitive to day-length toc.
作者认为，大豆开花前后的光周期反应都与某些特定基因的表达有关。
It was proposed that both pre-and post-flowering photoperiodic responses in soybeans were related to the expression of certain genes.
在相同区域中，不同生存微环境的近缘种类的有性生殖的光周期反应有所不同。
Photoperiodic responses of SR are distinct in closely related species inhabiting overlapping but different micro habitats.
数据分析可以看出：对光周期反应越敏感的指标，与花芽分化时期的相关性也越大；
It indicates that the more sensitive of growth characteristics to photoperiod, the more significant relationship between growth characteristics and flower bud differentiation phase.
对小麦品种的春化作用、光周期反应及其与发育进程的关系进行了量化分析和动态模拟。
Quantitative analyses and dynamic simulation were undertaken on vernalization, photoperiod response, and their relationships to development progress in wheat.
对光周期反应敏感的亚热带自交系CML312表现异常，基本营养生长期指标在自交系内及其F1内变异较大；
The performance of the basic vegetative stage in the CML312 line with sensitivity to photoperiod is abnormal with higher CV within the line and F1.
虽然同一个居群长期受到相同光周期诱导，但是种群不是有单一相近的开花期，存在着开花光周期反应不同的基因型。
It was observed that there were different genotypes for genetic flexibility in flowering photoperiodic response, although the populations had always been subjected to the same photoperiodic induction.
这种反应属于典型的光周期现象，而不是由温度的替代作用、光合时间的改变或前期短日后效应引起的。
The respose was not caused by the effects of temperature, photosynthetic duration or pre-flowering photoperiodic after-effect but was typical photoperiodism.
