试验证实,同条件下不同品种的种子发芽力的差异来自发芽势,发芽势是室内和田间幼苗生长快而健壮的基础(未发表)。本试验测定了同条件下不同品种的萌发差异和与发芽势的关系,以求为选育发芽势高的育种材料,和为栽培选用发芽力高的种子提供依据。 1 材料和方法 1989～1992年在本校农场相同条件下种植了山东目前主栽品种(系)26个,随机区组排列,重复4次,小区面积5.4平方米。种子收获后,待自然通过休眠期,用标准法做发芽试验,重复4次,每次100粒,从中选发芽势有代表性的12个材料再测种子萌发(纸床法),重复2次,每次100粒,分别供测吸胀和萌动。种子浸泡后2、5、8、13、18、23、28、33小时各测一次吸胀
The results showed that the difference of seed germination ability of different varieties under the same conditions came from the germination potential, which was the basis of rapid and robust growth of indoor and field seedlings (unpublished). In this experiment, the germination differences and the relationship between the germination potential of different varieties under the same conditions were determined in order to provide the basis for breeding breeding materials with high germination potential and for selecting germinating seeds with high germination ability. 1 Materials and Methods From 1989 to 1992, 26 cultivars (lines) of Shandong Province were planted under the same conditions of our school farms, and were randomly arranged and repeated 4 times with a plot area of 5.4 square meters. Seed harvest, to be naturally through the dormant period, the standard method of germination test, repeated 4 times, each 100, from which to select the representative of the sprouting potential of 12 materials measured seed germination (paper bed method), repeated 2 times , Each 100, respectively, for measuring the swelling and sprouting. 2,5,8,13,18,23,28,33 hours after the seed soak once each measured swelling
