河北省油葵品种多点比较试验分析

为筛选适宜河北省不同生态区的油葵新品种,分别在冀北高寒区张家口市、冀中南太行山浅山丘陵区石家庄市、冀中南太行山前平原区衡水市饶阳县开展油葵品种多点比较试验,对收集到的9个油葵品种的主要农艺性状及产量进行丰产性、稳定性分析。研究结果表明：（1）‘F60’、‘T562’和‘早熟矮大头’的生育期较对照短,其余品种均比对照长。（2）‘新葵23号’和‘新葵7号’比较高大,‘早熟矮大头’相对矮小。（3）‘T562’籽粒较好,百粒重最重,‘HZ001’籽粒小而轻。（4）各参试品种均表现增产,其中‘T562’和‘F60’丰产效应最高。张家口和石家庄‘T562’产量最高;饶阳‘F60’产量最高。（5）‘新葵7号’和‘F60’变异度最低,稳产性最强。‘T562’、‘F60’、‘新葵7号’、‘改良7号’和‘S667’适宜张家口种植,‘F60’、‘早熟矮大头’、‘新葵7号’、‘HZ001’和‘新葵23号’适宜石家庄和饶阳种植。（6）‘T562’、‘F60’综合评价好,‘早熟矮大头’、‘新葵7号’、‘HZ001’和‘新葵23号’综合评价一般,‘改良7号’和‘S667’综合评价较差。     

Inductively coupled plasma mass‐spectrometric determination of platinum in excretion products of client‐owned pet dogs

Residues of antineoplastic drugs in canine excretion products may represent exposure risks to veterinary personnel, owners of pet dogs and other animal care‐takers. The aim of this study was to measure the extent and duration of platinum (Pt) excretion in pet dogs treated with carboplatin. Samples were collected before and up to 21 days after administration of carboplatin. We used validated, ultra‐sensitive, inductively coupled plasma‐mass spectrometry assays to measure Pt in canine urine, faeces, saliva, sebum and cerumen. Results showed that urine is the major route of elimination of Pt in dogs. In addition, excretion occurs via faeces and saliva, with the highest amounts eliminated during the first 5 days. The amount of excreted Pt decreased over time but was still quantifiable at 21 days after administration of carboplatin. In conclusion, increased Pt levels were found in all measured excretion products up to 21 days after administration of carboplatin to pet dogs, with urine as the main route of excretion. These findings may be used to further adapt current veterinary guidelines on safe handling of antineoplastic drugs and treated animals.     

早春设施大棚苦瓜品种比较试验

2013-2014年在设施大棚条件下,以玉云苦瓜为对照,对新翠、翠玉、雅秀、春晓1号、翡玉5个苦瓜品种进行对比试验。试验结果表明,新翠苦瓜早熟、商品性优、生长势强,产量达5 394.3 kg/667 m2,综合性状优于其他5个品种,是平和地区早春设施大棚大面积种植的首选品种。     

8个豇豆新品系的比较试验

以之豇28-2为对照,对8个新选豇豆品系的早熟性、农艺性状、抗病性和产量进行了试验比较,试验结果表明,品系2-13-8和5-10-7熟性较早,后期翻花能力强,采收期长,荚长、荚粗和单荚质量有较大优势,田间对枯萎病、疫病、病毒病等表现出较强抗性,前期产量和总产量高,667 m2产量分别达3206.05、3294.98 kg/667 m2,与对照差异分别达显著和极显著水平,因此,2-13-8和5-10-7可作为长沙地区的优良早熟豇豆新品系进行深入研究。
