| 摘 要： | 通过利用中熟中粳稻苏香粳3号在孕穗至灌浆成熟期分别进行高温热害处理,结果表明:连续高温降低了苏香粳3号的结实率和千粒重,且高温处理时间越长,其结实率和千粒重的下降幅度越大;处理期内日平均最高气温为37℃,孕穗至抽穗期的日最高气温高于40℃的时间达8 d,其最低结实率和千粒重分别达72.2%和16.2 g,表现出较强的耐热性。

| Abstract: | In this paper,the heat resistance of middle-mature japonica rice Suxiangjing No.3 was studied through high temperature treatments from booting stage to mature stage.The results showed that the continuous high temperature reduced the setting rate and 1000-grain weight,and their descend range increased when the time of high-temperature treatment prolonged.The average daily maximum temperature in the treatment period was 37 ℃,there were 8 days when daily maximum temperature was above 40 ℃ from booting stage to heading stage,and the minimum setting rate and 1000-grain weight were 72.2% and 16.2 g respectively,so this variety appeared strong heat resistance. |
