| 摘 要： | 以珍汕97A、测64-7为材料，研究了杂交稻制种扬花期温湿互作配比对开花及颖花酶活的影响，结果显示温湿度对父母本开花的影响不同。花时同步指数与温湿配比之间存在着二次抛物线回归关系。花时相遇状况与温湿配比有关，在扬花期存在一个最适温湿互作配比(汕优64为40)。过氧化物酶、过氧化氢酶活性在不同湿度下受温度的影响不同。 |

| Abstract: | Effect of temperature and humidity combination on flowering habits and activity of enzyme in spikelets were studied using Zhenshan 97A (cytoplasmic male sterile line) and Ce 64 7(restorer line) as materials. Temperature and humidity ratio affected differently flowering habits of cytoplasmic male sterile line and restorer line. A quadratic regression could be used to describe the relationship between index of blooming time synchronization (IBTS) and temperature and humidity ratio. There was a optimum temperature and humidity ratio at flowering stage (40 for Shanyou 64). Activity of enzyme (peroxidase, catalase) in spikelets was differently influenced by temperature under different humidity. |
| Keywords: | hybrid rice seed production temperature humidity flowering habit enzyme activity |
