查询词典 Puccinia

Genes for resistance to leaf rust in twenty-four important wheat cultivars from six wheat breeding institutes or companies were analyzed using fourteen isolates of Puccinia triticina.

选用14个具有不同毒性基因组合的叶锈菌系，推导分析了来自山西省6个育种单位和种子部门的24个重要小麦品种所携带的抗叶锈病基因状况。

All of these had shown that the induced resistance could be transmitted.Oligosaccharides had not shown any direct activity against Puccinia striifomis in vitro. This suggests that Oligosaccharides can elicit resistance to diseases of wheat, and are different from common pesticides.

不同浓度(25ppm、50ppm、100ppm)的5号提取物的体外抑菌试验表明，低聚糖对条锈菌没有明显的抑制作用，说明低聚糖不具有直接杀菌或抑菌作用，使小麦产生抗锈性的原因在于诱发寄主植物的抗病潜能，使植物本身产生对病原菌的抗性，这与普通杀菌剂显然不同。

TcLr9,TcLrl9,TcLr38 and TcLr45 are resistant to Puccinia triticina race No.

本研究以编号05-21-116③的小麦叶锈菌为接种菌株，其致病类型为THTS。

我国小麦条锈病危害普遍而严重，培育和应用抗病品种是防治小麦条锈病最经济、安全、有效的方法。

Hylogenetic analysis indicated that PsCdc2 showed high similarity with Cdc2 from Puccinia graminis (73.1%), Cryptococcus neoformans (72.4%) and Ustilago maydis (70.4%), respectively.

sCdc2基因编码蛋白与小麦秆锈菌、新型隐球菌、玉米瘤黑粉菌等多种真菌的Cdc2高度相似，其中与小麦秆锈菌的Cdc2亲缘关系最近，序列相似性达73.1%。

A cluster analysis of two-hundred candidate wheat cultivars from Shaanxi, Gansu, Sichuan and Henan provinces recently was performed by using unweighted pair-group average method,based on the data from their seedling resistance reaction to six dominant isolates of Puccinia striiformis with the different virulence.

为了弄清我国小麦条锈病主要流行区后备小麦品种的抗锈性，选用6个条锈菌优势菌系，对陕，甘，川，豫四省近年来培育的200份后备小麦品种进行苗期和成株期鉴定，并分别对不同省份后备品种的抗条锈性进行聚类分析。
