水稻开花抗寒性频率的研究

A Study of the Resistant Frequency in Rice Flowering

本文用不同的抗感品种的开花期资料，以动力学模拟方法计算了不同品种，不同稻穗，不同枝梗的开花的动力学方程，获得了方程中各参数．根据动力方程中各参数，计算了品种间，穗间，枝梗间的抗性差异与固有频率，频率，衰减因子和相角之间的关系，进一步证明了过去在穗枝梗上的抗性趋势结论，同时又获得了一些新的结论．这表明了水稻在低温下的抗性差异在动力学系统中是与频率，衰减因子和相角有关，这个结论在国内外的抗性文献中未见报道。

Dynamic equation of flowering stage in varieties, panicles and primary branches were Calculated with dynamic simulation method in two varieties with different temperature resistance. This confirmed that along with primary branches from top to low part of panicle, the natural frequency (ωn), frequency (ω), attenuation factor (e-bt) and phase Angle (θ) all changed and showed correlation between primary branches and parameters above notably. Those conclusions agree with others, and show that dynamic simulation methods are trustworthy.
