摘    要:研究结果表明,在同一年份、同一地点、同一栽培条件下,152份小麦品种(系)自然感染黑胚病的程度有差异,其中2份免疫,81份抗病,69份感病,病拉率在0~68.83%之间。黑胚粒与正常粒相比,90%品种(系)千粒重增加,10%品种(系)千粒重降低,且千粒重增减与其病粒率高低无关。同一品种(系)4级种子和0级种子相比,发芽势、发芽率、出苗率明显降低,苗干重、根干重减轻,病苗率提高。

关 键 词:小麦黑胚病  抗病性  发芽势  发芽率  千粒重

Abstract:The test results indicated that there was difference among wheat varieties of 152 num in severity of black embryo disease. In the test two were immunity,eighty-one were re- sistance,sixty-nine were infection,rate of disease grains was 0~68. 83% in the same year, same region and same cultivatied techniques. Comparing with normal seed,thousand kernel weight of 90% black embryo seed was increased, 10% was reduced. There was no correlation between thousand kernel weight increased or reduced and rate of disease grains ralsed or lowed. On same variety the seed of fourth grade comparing with zero grade of seed,germina- tive force, germination percentage and seeding emerged percentage were significantly re- duced. Seed dry weight and Root dry weight were reduced and disease weed percentage was increased.
Keywords:black embryo disease of wheat   disease resistance   germinative force   germination percentage   thousand kernel weight
