摘  要:
杂交稻制种过程中常因气候因素而导致穗发芽,影响产量品质。研究表明田间穗粒有多种表现形多,依发芽程度可分为5级。发芽愈明显.级别愈高,则经济性状损失也意明显。芽粒的发芽率和千粒重与发芽程度呈线性相关。田间有效调控药剂为烯效唑和青鲜素。

摘  要:
The seeds germinate and the properties lose because of the some of the climatic anomalies. It's reported thatthe germination seeds is classed by five grades. The more the seeds sprout,the high the grade is. And tbe economicsloss is higher. The germination percentage and the seed weight are in line with the getmination grades. The effective control combinations are s07 and MH.
