Eighty-one wheat accessions including 50 southern regional performance nursery （SRPN） lines and 31 northern regional performance nursery （NRPN） lines from the United States were tested to evaluate the growth habit by chilling treatments and to estimate the VRN allele variation with 19 pairs of published VRN primers. Two spring wheat accessions and 44 semi-spring wheat accessions were confirmed based on their chilling days＇ requirement and polymorphism was found at VRN loci. The Vrn-A1 allele had the highest frequency in the RPN accessions and VA1-CAPs markers identified growth habit of RPN lines. No polymorphism was found at the VRN3 loci and some polymorphism at the region of promoter and the first intron of VRN1 was not always consistent to growth habit in the wheat RPN accessions. The existence of variation in VRN alleles suggested that singly using the dominant Vrn allele is possible to extend the diversity of wheat accessions and improve their adaption to different environments in autumn-sowing region. This information will be useful for the cultivars exploitation and wheat breeding program.

A series of physical tests are conducted to examine the characteristics of the wave loading exerted on circular-front breakwaters by regular waves. It is found that the wave trough instead of wave crest plays a major role in the failure of submerged circular caissons due to seaward sliding. The difference in the behavior of seaward and shoreward horizontal wave forces is explained based on the variations of dynamic pressure with wave parameters. A wave load model is proposed based on a modified first-order solution for the dynamic pressure on submerged circular-front caissons under a wave trough. This wave loading model is very useful for engineering design. Further studies are needed to include model uncertainties in the reliability assessment of the breakwater.

[目的]探究黄土高原地区气象干旱的时空变化特征及其影响因素,以期为该地区的干旱监测、旱作农业粮食生产、水资源管理及生态恢复建设提供科学支撑。[方法]基于黄土高原地区119个站点1957—2019年逐日气象资料,使用FAO Penman-Monteith公式计算了日尺度潜在蒸散发及标准化降水蒸散指数(SPEI),并采用Theil-Sen Median斜率估计和Mann-Kendall趋势分析,探讨了干旱天数、干旱事件发生次数和强度的分布特征及变化趋势。同时,使用皮尔逊相关系数分析气象因子与干旱指标的关系,并结合土地利用类型转移矩阵探讨了人类活动对气象干旱的影响。[结果](1)日尺度SPEI在识别干旱天数、干旱事件发生次数和强度方面比月尺度SPEI更为精确;(2) 1957—2019年黄土高原西北地区干旱事件发生次数增加,大部分区域干旱强度呈现不断增加的趋势,不同类型干旱的天数有所降低;(3)黄土高原东南部和西北部地区存在明显的变干趋势,而北部和南部地区则呈现出湿润化趋势;(4)气象因子与干旱指标之间存在中等相关关系,土地利用/地表覆盖对黄土高原地区的气象干旱产生了一定程度的影响。[结论]黄土高原地区的气象干旱受气候因素和人类活动的双重影响,其时空变化特征复杂。研究结果为该地区的干旱监测与管理提供了重要的科学依据。
