种子的萌发与物质转化和能量交换紧密相关,对种子萌发过程中的热效应进行研究,有助于认识种子的萌发机理及其影响因素。采用武汉大学研制的新型热导式微量量热计测定了刺槐种子的萌发生热曲线。分析了其萌发生热规律与种子萌发生理之间的关系。并根据动力学原理对其生长阶段的热谱进行分析,建立了刺槐萌发生长的动力学模型,25℃ P=208.77/[0.1937+0.8063exp(-0.06563t)]
Germination of seeds is closely related to material transformation and energy exchange. Studying the thermal effect during seed germination can help to understand the germination mechanism and its influencing factors. A new thermal conductivity microcalorimeter developed by Wuhan University was used to determine the germination heat curve of Robinia pseudoacacia seeds. The relationship between germination heat regulation and seed germination physiology was analyzed. The kinetic model of the growth of R. pseudoacacia was established based on the kinetic principle. The kinetic model of the growth and development of R. pseudoacacia was established. The kinetic model was established at 25 ℃ (P = 208.77 / [0.1937 + 0.8063exp (-0.06563t)])
