日本东北地区孕穗期低温诱导小穗不育的低温风险图Hiroyuki SHIMONO*和Hiromitsu KANNO** *岩手大学农学院，3-18-8上田，森冈，岩手，020-8550，日本**NARO东北农业研究中心，森冈，岩手，020-0198；孕穗期低温造成的产量损失是影响日本北部水稻生产的一个关键因素。关于孕穗期考虑到水稻生长阶段的温度空间分布的资料很少。本研究分析了日本东北地区水稻孕穗期关键阶段的气温空间分布，以及影响水稻生殖生长早期和营养生长后期耐冷性的其他两个阶段的气温空间分布，绘制了水稻冷害风险图。在启动阶段温度较低的地区位于东北北部和东部。利用残差与启动阶段和其他两个阶段的温度数据分别进行回归分析，突出了启动阶段低温导致冷损伤风险较高的区域；生殖生长早期和营养生长后期温度较低，与孕穗期温度相同。为了减少冷损害的风险，控制种植计划是一个强有力的选择。抽穗期推迟一周可使孕穗期和其他两个生育期的临界温度提高1℃。
Risk map for cool injury inducing spikelet sterility by low temperature at booting stage in rice with taking into account for growth stage and temperature before the booting stage in Tohoku region, Japan Hiroyuki SHIMONO* , and Hiromitsu KANNO** *Faculty of Agriculture, Iwate University, 3-18-8 Ueda, Morioka, Iwate, 020-8550, Japan **NARO Tohoku Agricultural Research Center, Morioka, Iwate, 020-0198, Japan Abstract Yield losses caused by low temperatures at the booting stage are a critical factor for producing rice in northern Japan. There is little information available on the spatial distribution of temperature at the booting stage that takes into account rice growth stages. The present study analyzed the spatial distribution of air temperatures not only at (1) the critical stage of the booting stage, but also at the two other stages that affect cold tolerance of (2) the early reproductive growth stage and (3) the late vegetative growth stage to produce a risk map for cold damage to rice in the Tohoku region of Japan. Regions that have lower temperatures at the booting stage are located to the north and east sides of Tohoku. Regression analysis using residual with temperature data at the booting stage and other two stages, respectively, highlighted the regions that carry a higher risk for suffering cold damage due to low temperatures at the booting stage; lower temperatures at the early reproductive growth stage and also at the late vegetative growth stage under temperatures identical to the booting stage. To reduce the risk for cold damage, manipulation of the cropping schedule is a powerful option. Delaying the heading date by one week can increase the critical temperature at the booting stage and also at the other two stages by up to 1°C.
