| 摘 要： | 为了解杂交水稻种子带菌情况及保活剂处理后贮存2年对种子发芽的影响，收集了湖南长沙、沅江、常德、临澧等地的杂交水稻种子，保活剂处理前后通过组织分离了解种子带菌情况，同时测定了种子水分含量与发芽率。结果表明：不同来源杂交稻种子携带的真菌主要为曲霉、毛锥孢、链格孢与镰刀菌。不同地区不同组合携带的真菌种类有很大的差异。1999年收获的杂交稻种用保活剂处理后保存2年，携带真菌数量减少，发芽率比对照高1．8％－15．9％；2000年用保活剂处理的杂交稻种保存1年后，发芽率比对照高0．3％－11％。

| Abstract: | Seed borne fungi and effect of Baohuoji on seed germination were determined.The results showed that Aspergillus spp. , Trichoconiella padwichii, Alternaria spp. and Fusarium spp. were main seed borne fungi on the seeds of 14 major hybrid rice combinations from Yuanjiang, Changde,Changsha and Linli in Hunan Province. The fungi on the seeds expressed significantly difference among examined combination. The fungi number was reduced markedly on the seeds stored 1~2 years. Baohuoji ( a new kind of seed coating formulation) had good effect on seeds germination. The germination rate of the seeds treated by Baohuoji increased 0.3%~15.9% when compared with the germination rate of the seeds,which were not treated by Baohuoji. |
