热分析法研究马协水稻花药的发育及败育过程

STUDIES ON THE DEVELOPMENT PROCESS OF THE MAXIE RICE ANTHERS BY MEANS OF THERMAL ANALYSIS METHOD

用热分析法研究了花粉不同育期马协保持系与不育系水稻花药的热分解过程，获得了花粉不同育期马协保持系与不育系水稻花药的ＴＧ／ＤＴＡ曲线，初步探讨了马协水稻花药的热分解规律及发育过程中花药干物质含量与发育期的关系．计算了马协保持系水稻花药发育的表观动力学参数，建立了相应的动力学经验式，并讨论了马协不育系水稻花药的败育过程．

The thermal analysis method was used to study the pyrolytic process of the anthers of the different developing stages of pollens from the fertile and male sterile lines of Maxie rice. The TG/DTA curves of the anthers were obtained. From these curves, the regularity of the pyrolysis of the anthers were studied. The relationship between the material changes of the anthers in the development process and their development stages of pollen were discovered. The apparent kinetic parameters and the experimental kinetic equations for the development of the fertile anther of Maxie rice were calculated and established.Furthermore,the abortion process of the male sterile anther of Maxie rice were discussed in the paper.
