摘要
采用适合黑龙江省第三积温带栽培的水稻品种共计46份。通过在返青期叶片数量和穗长数据分析认为:02-011-2、04-582、485、05-397、01-107、龙粳21、03-805、01-806、00-108、05-4035、01-687、04-2182、04-107、06-2351、05-4076,在返青期耐低磷胁迫性较强,其中02-011-2分类等级最高。穗长分类处理中04-582、02-011-2、龙花00-446、龙粳21、01-687、01-558、06-2351、05-4076、垦稻14类别较高,因此低磷胁迫抗性较强。综合返青期叶片数和穗长分析认为:02-011-2、04-582、龙粳21、01-687、05-4035、06-2351等6份材料对低磷胁迫适应性较强。
In this study,46 rice materials were used,which suited the third accumulated temperature zone in Heilongjiang province.Through analysis with leaf number and panicle length data,the result showed that some materials had stronger tolerance to low-phosphorus stress in greenturning period,such as 02-011-2,04-582,485,05-397,01-107,Longjing 21,03-805,01-806,00-108,05-4035,01-687,04-2182,04-107,06-2351 and 05-4076,one of the strongest classification was 02-011-2.In classification treatment of panicle length,those materials had stronger classification,such as 04-582,02-011-2,Longhua 00-446,Longjing 21,01-687,01-558,06-2351,05-4076 and Kendao 14,so those materials had stronger tolerance to low-phosphorus stress.Composite result of leaf number and panicle length data showed that 6 rice materials had stronger tolerance to low-phosphorus stress,such as 02-011-2,04-582,Longjing 21,01-687,05-4035 and 06-2351.
