GB/T 3543.1～7-1995《农作物种子检验规程》颁布实施,实现了种子检验结果具有标准性和可比性,从而满足了我国种子贸易发展的需要,也为国际间种子贸易提供了必要依据。该规程对水稻发芽规定了多种方法,但各地用法各异。为寻求较便捷、适宜的试验方法及探索新规程推荐的发芽方法之间差异与合理性,我们进行了此试验。1 材料和方法1.1 试验材料选用生产上常用的三系杂交稻组合汕优63和两系杂交组合两优培九、丰两优1号,种子由合肥丰乐种业股份有限公司提供。
GB / T 3543.1 ~ 7-1995 promulgated and implemented Crop Seed Inspection Regulation, which has achieved the standardization and comparability of seed test results, thus meeting the needs of the development of seed trade in our country and providing the necessary basis for international seed trade. The regulation provides a variety of methods for rice germination, but different ways of use. We conducted this trial to find out the differences and rationality between the more convenient and suitable test methods and to explore the germination methods recommended by the new protocol. MATERIALS AND METHODS Experimental materials The three-line hybrid rice combination Shanyou 63 and two-line hybrid combination Liangyoupeijiu and Fengliangyou 1, which are commonly used in production, were provided by Hefeng Fengle Seed Industry Co., Ltd.
