种子萌发生长的微量热及非平衡热力学研究

The thermograms of the germination and growth of rice and tree seeds were determined and studied by using a newly constructed microcalorimeter build in this laboratory at Wuhan University. The thermograms show the existence of physiological triphasic patterns (including imbibition,activation and growth stages)in the germination and growth process. Nonequilibrium thermodynamics of the germination and growth of seeds was considered under given conditions, and the thermodynamic functions of the germination and growth of seeds were calculated.

细胞质雄性不育系稻种萌发生长的热力学及动力学比较研究

用自研制的新型热导式微热量计测定了野败型（珍汕97）和红莲型（丛广41）保持系（B）和不育系（A）稻种萌发生长热功率──时间曲线。用热力学方法计算了野败型和红莲型稻种萌发生长的焓变（耗散热）。用动力学方法计算了野败型和红莲型稻种萌发生长的动力学参数，建立了相应的动力学经验式。并讨论了保持系与不育系稻种萌发生长的热力学及动力学差异。
