| 摘 要： | 对2010年郑州地区收获的257份小麦品种(系)进行了黑胚率统计,并以发病较重的周麦18和漯麦4-168两个品种为材料,分析了黑胚病对种子发芽势、发芽率、发芽指数等发芽特性以及苗高、根长、单株质量等幼苗生长指标的影响。试验结果表明:257份小麦品种(系)的黑胚率介于0~54%,其中豫麦35号、百泉41等77个品种的黑胚率低于1%,济程2号的黑胚率最高,达到54%。70%的品种(系)黑胚率低于5%,80%的品种(系)病粒级别较低(0-2级),与往年比较,2010年郑州小麦黑胚率降低。周麦18黑胚率为18.0%,黑胚粒发芽势、发芽率、发芽指数、根长、苗高与单株质量均降低,其中0-1级与2-3级种子间差异极显著;漯麦4-168黑胚率为25.7%,病粒的发芽与幼苗生长指标也降低,但不同病级间的差异不显著。

| Abstract: | The 257 wheat cultivars and lines were harvested to study black point disease in Zhengzhou in 2010.The black point kernel ratio ranged from 0 to 54%.70% cultivars or lines had a ratio below 5%,and the disease severity of 80% cultivars ranged from 0 to 2nd scale.The general black point kernel ratio in 2010 was lower than usual.Zhoumai 18(black point kernel ratio of 18.0%)and Luomai 4-168(black point kernel ratio of 25.7%)were relatively susceptible to black point disease,and were used to investigate the seed... |
