），说明早稻型恢复系主茎叶片数的多少，将影响着抽穗夭数；六种恢复系中，福恢０１６、福恢９１１、测６４和水源２８７表现极显著水平，福恢０９０和福恢９１３未表现出农１早季任复来不同勇猢的生物学特性注：”有效积温以１２℃和２７Ｃ为上下限温度来计算，表３同。显著的相关；而同一播期中所有的恢复系却未表现出相关的显著性。（２）有效积温与抽穗天数早稻型恢复系总体表现出负相关（－０·２０３５），但未达到显著水平；但程度差异较大，其中测６４为显著水平（一０．９５８９”），说明不同的恢复系对温度敏感程度有较大的差异；而同一播期的所有恢复系都表现出正亵２早稻位复系不同槽钢备性状的变异来３几个早稻恢复系生物学特性的相关相关，其中３月２１日、４月２０日和５月５日则表现出极显著或显著关系，说明同一播期中，不同的品种要达到一定的抽穗有效积温，是通过播至抽的天数来实现的。（３）有效积温与主茎叶片数早稻型恢复系总体表现出负相关（－０．０３０５），但未达到显著水平；六个品种也表现出负相关，但差异程度较大，其中测６４为显著水平（－０．９６３４“），说明同一品种在不同的播期中，对温度敏感程度差异较大；而同一播期所有的恢复系又表现出正相关。三、小结?
), Indicating that the number of main stem leaves of early rice restorer lines will affect the number of heading stages; among the six restorer lines, Fuhui 016, Fuhui 911, test 64 and water source 287 showed extremely significant levels, Fuhui 090 and Fuhui 913 did not show the biological characteristics of different coughs in Renfu 1 in the early season. Note: “The effective accumulated temperature is calculated at upper and lower limits of 12 ° C and 27 ° C, with significant correlations with Table 3. In the same sowing period (2) The effective accumulated temperature had a negative correlation (-0.2035) with the number of heading days, but it did not reach the significant level, but the difference was significant 64 for the significant level (a 0.9589 ”), indicating that different restorers have a greater sensitivity to temperature sensitivity; and all the restorer lines of the same sowing date showed positive response 2 different rice trough the different channel preparation properties The variation was related to the biological characteristics of several restorer lines of early rice, in which March 21, April 20 and May 5 showed significant or significant correlation , Indicating that broadcast the same period, different breeds to reach a certain heading effective accumulated temperature, is achieved by the number of days to broadcast smoked. (3) The effective accumulated temperature was negatively correlated with the number of early rice restorer lines (-0.0305), but did not reach the significant level. Six cultivars also showed a negative correlation, but the differences were significant 64 was a significant level (-0.9634 "), indicating that the same species in different sowing dates, temperature sensitivity are quite different; and restore the same sowing period all showed a positive correlation.
