Traits of shattering resistant buckwheat ‘W/SK86GF’

Seed shattering is a significant problem with buckwheat, especially at harvesting time. Several reports have shown that a green-flower mutant of buckwheat, such as W/SK86GF, has a strong pedicel. Although a strong pedicel may provide some resistance to shattering in the field, no study has thoroughly examined this issue. In this paper, we demonstrate that a W/SK86GF has shattering resistance by comparing the degrees of shattering of W/SK86GF and Kitawasesoba (leading variety of Hokkaido with non-green-flower traits) through a test for four years, including a typhoon hit year in the field. In a non-typhoon year, the shattering seed ratio (shattering seed weight/(yield + shattering seed weight) × 100) of W/SK86GF at maturing time +15 days (+15D) was lower than that of Kitawasesoba. In a typhoon hit year, the shattering seed ratios of Kitawasesoba at maturing time and +15D were surprisingly high, 14.4 and 21.1%, respectively. On the other hand, those of W/SK86GF were only 3.08% and 2.57%, respectively; indicating W/SK86GF is promising as a shattering resistant line even in a typhoon hit year. From these results, shattering resistance of W/SK86GF can be evaluated after maturing time such as +15D and pedicel strength would confer W/SK86GF a shattering resistant trait.

进口小麦中超标麦角的色选机剔除处理技术初探

通过色选机对进境小麦麦角超标进行加工处理,以剔除混在进境小麦中的麦角.结果显示:色选机可以剔除大部分麦角,使其含量降至国家标准以内.我们推荐参数(使用布勒-SORTEX B色选机时)为:小麦流量不超过设计产能80％,色选机初选异色剔除粒、疵点剔除粒分别设定为55％、50％,色选机复选异色剔除粒、疵点剔除粒分别设定为50...     

粘粒含量——夏季风的良好替代指标

通过对位于东亚季风区尾闾部位的沙沟剖面、东部半湿润区王官剖面、东部湿润区扣马剖面的气候代用指标的分析发现 ,黄土地层中 <5 μm的粘粒含量指标对各剖面中黄土-古土壤序列指示得比较清晰 ,可以较好地反映东亚夏季风的变化。对黄土地层中粘粒含量的测试及其环境意义分析以及与经典的东亚夏季风的替代指标———磁化率、红度指标 (a )的对比分析发现 ,粘粒含量指标的意义比较明确 ,适应范围更广 ,灵敏性也较高 ,是一比较可靠的、新的东亚夏季风的良好替代指标。     

Evaluation of Egg White Protein-Based Coatings to Improve the Protection of Frozen Atlantic Salmon (Salmo salar)

ABSTRACT

The effects of different egg white protein coatings on Atlantic salmon quality preservation after 4 months of frozen storage were evaluated. These coatings increased the yield of the fillets and protected them from lipid oxidation, providing better protection than glazing. Egg white protein coatings were better options than glazing to preserve salmon color during frozen storage. The best results were obtained with the application of coatings before freezing. No clear effects of the type and concentration of plasticizer in most quality parameters were found. Egg white protein + glycerol 2:1 applied before freezing was the best coating for frozen Atlantic salmon protection.

彩色多普勒能量图与彩色多普勒血流图诊断肝血管瘤效果的比较

目的 :比较彩色多普勒能量图 (CDE)与彩色多普勒血流图 (CDFI)诊断肝血管瘤的效果。方法 :用 CDE与CDFI观察 2 8例 (36个 )肝血管瘤内的血流情况 ,比较两者的血流显示率。结果 :CDE和 CDFI对肝血管瘤内血流的显示率分别为 94.4%和 2 8.9% ,两者差异有非常显著性 (P<0 .0 1)。结论 :CDE对肝血管瘤的敏感性明显高于 CDFI,表明CDE对肝血管瘤的诊断及鉴别诊断有较大的应用价值。
