黑胚病在我国主要麦区普遍发生,已引起广泛的关注。本文对东北春小麦品种克旱18号黑胚籽粒与健粒进行发芽实验,结果表明,黑胚对发芽率影响不明显,对发芽势有一定的影响。结合实验结果对黑胚病的发生,影响因素及防治措施进行综述。

Black point is a general wheat disease in main wheat produce areas of our country.The breeders paid more attention to incidence of this disease.The experiment studied germination with health and infected seeds of Kehan 18 which is the spring wheat variety in northeast. The results showed that black point infected germination radio was not obvious, and its influnce on germination energy in some degree. Combing this experiment results, we＇ll have a introduction about incidence, factors, and prevent measures of black point.
