玉米种子胚较大,并含较高的脂肪,在夏季高温高湿条件下,会迅速衰老,降低活力和发芽率。为了探讨玉米杂交种度夏安全贮藏的技术措施,我们借用闲置的原战备山洞仓库,连续3年(2003～2005年)贮藏玉米杂交种子,试图为玉米杂交种子安全越夏贮藏提供一定的科学依据。1材料与方法1．1试材试材采用我市内推广面积较大的玉米杂交种沈单16号、辽丹933、三北六号、富友一号、沈玉17、农大108、连玉15号等7个组合,试材一律是2002年收获的新种子,原始发芽率均在85%以上,水分16%。种子是由凤城市叆阳镇农科站提供。
Corn seed embryos larger, and contains higher fat, under the conditions of high temperature and humidity in summer, will quickly aging, reducing vitality and germination rate. In order to explore the technical measures of safe summer hybrid corn seed storage, we borrowed the idle original war preparedness cave store for three consecutive years (2003 ~ 2005) to store the hybrid corn seed in an attempt to provide a scientific basis for the summer hybrid seed storage . 1 Materials and methods 1.1 The test material The test materials used in the city to promote the larger area of the hybrid corn Shen No. 16, Liao Dan 933, three North VI, Fuyou one, Shen Yu 17, Nong 108, Jade 15 and other combinations of 7, the test materials are all new seeds harvested in 2002, the original germination rate of more than 85%, moisture 16%. The seeds are provided by Fengyang Yingyang Agricultural Station.
