1巨峰和无核早红葡萄在越南谅山试种观察显示文摘[目的]观察巨峰、无核早红葡萄在越南谅山省的引种表现,为其在越南推广种植提供参考依据.[方法]2009年春从中国南宁引入巨峰、无核早红两个鲜食葡萄品种在越南谅山省试种,调查其枝蔓生长量、物候期、果实性状、产量等相关指标.[结果]至第1年抚育冬季,巨峰葡萄枝蔓总长234.5 cm,上架茎粗0.84 cm;无核早红葡萄枝蔓总长294.1 cm,上架茎粗0.86 cm.在物候期方面,巨峰葡萄从萌芽至果实成熟需141~151 d,表现中熟;无核早红从萌芽至果实成熟需142~151 d,未表现其应有的早熟特性.在果实性状方面,巨峰葡萄2010~2012年3年平均单果重8.9 g,种子数1.04粒,可溶性固形物(TSS)含量17.5%;无核早红葡萄2010~2012年3年平均单果重6.8 g,TSS含量13.9%.在产量方面,巨峰葡萄2010~2012年产量分别为13.69、17.50和16.24 t/ha;无核早红葡萄2010~2012年产量分别为10.81、16.02和20.92t/ha.[结论]巨峰葡萄在越南谅山省种植表现丰产稳产优质,具有较好的适栽性,可大面积推广种植;无核早红葡萄表现丰产稳产,但表现低糖低酸,极易裂果,着色困难,不宜在越南大面积发展.黄江流 PHAM Thi Thang 罗瑞鸿 NGUYN Thi Hà 吕荣华 LUONG Dǎng Ning CHU Vǎn DUòng NGUYN Manh Tòng 彭宏祥 Ly Ming Nguyet LU'O'NG i Thuy CHU Xun Tien VI Vǎn Dúc NGUYN Duy Dng Ly Dúc Khiêm 熊俏 2014南方农业学报2014,45,7:5
2精液叶酸、维生素B_(12)、活性氧水平与精子质量关系研究显示文摘目的 : 检测人精液叶酸、维生素 B12 ( VB12 ) ,及活性氧 ( ROS)的含量 ,探讨三者与精子质量的关系。方法 : 收集经证实配偶已怀孕的新加坡籍健康成年男性 1 76名的精液 ,根据WHO推荐方法检测精子质量各项指标 ,并测定精液叶酸和 VB12 含量及 ROS水平。结果 : 平均精液量、精子浓度和其活力都在正常范围内。而精子存活率 ( 73.0 6% )略低于 WHO标准 (≥ 75% ) ,形态异常的精子 ( 77.0 6% )高于 WHO标准 ( 70 % )。精液的叶酸含量与 ROS水平呈显著负相关 ( r=- 0 .2 5,P=0 .0 0 3) ;VB12 与 ROS呈负相关 ( r=- 0 .2 5,P=0 .0 0 2 ) ,与精子形态异常也呈负相关( r=- 0 .1 5,P=0 .0 4 8) ,但与精子浓度呈正相关 ( r=0 .31 ,P<0 .0 0 1 )。ROS与精子形态异常呈正相关 ( r=0 .2 5,P=0 .0 0 2 ) ,与精子活力也呈正相关 ( r=0 .1 9,P=0 .0 1 9)。结论 : VB12 对精子生成和维持精子正常功能是必需的 ,ROS水平与精子功能缺陷有关 ,VB12 和叶酸可能通过降低 ROS以维持精子的正常功能。陈起萱 梅节 V Ng SE Chia 凌文华 CN Ong 2001营养学报2001,23,2:2
