Wheat varieties and leaf rust samples of Hebei province were collected in 1982 and study of interaction between host and pathogen was made in 1983. The results expressed by virulence frequency showed that this method of investigation provided directly the information of the interrelationship between the wheat varieties and the rust fungus .

我科研组采取毒力频率来研究河北省小麦品种和河北省叶锈菌的相互作用，我们认为：这种研究方法能直接反应品种与菌株之间相互作用的情况，对生产者和抗病育种工作者提供的信息，要比小麦叶锈菌小种鉴定提供的以编号对小种命名的小种名单要有用得多。

In order to discuss the signal transduction mechanism,wheat cultivar Lovrin10 and different leaf rust fungus races were used to form compatible and incompatible interaction groups to study the role of drugs affecting calcium metabolism and calcium channel on HR induced by wheat leaf rust fungus.

为进一步探讨小麦抵抗叶锈菌侵染的防卫反应的信号转导机制，利用小麦品种洛夫林10和不同叶锈菌生理小种组成亲和与不亲和组合，研究影响Ca2+代谢和钙通道的药物对小麦受叶锈菌侵染后诱发的HR的作用。

The paper is to research physiological differentiation and DNA polymorphism of MLP. The main result is as follows: 1.Investigating the Poplar Resistance: the difference of sensitivity is prominent.Other poplars are infected by Melampsora larici-populina in different degree, except that Populus deltoids and Populus deltoides×P.

本论文主要是对来自西北，华北，东北和西南等省的多种落叶松—杨栅锈菌进行同工酶分析以及DNA多态性研究，得出如下结论：(1)寄主抗病性调查：杨树各派树种对落叶松杨栅锈菌的感病性差异明显，除美洲黑杨和中绥12号外，所有的杨树品种都不同程度地感染了落叶松杨栅锈菌。

Results Observation of 35 746 grain of airborne fungi spores and 1 188 grain of fungi spores for one year revealed the following species of fungi: Ustilaginales, Aternaria, Uredinales, Clodoporium cladosporioides, Cladosporium, Pithomyces, Cladosporium macrocarpum, Aspergillus niger, Aspergillus versicolor and Aspergillus fumigatus. Thirth-nine of 85 infants and young children with asthma (45.9%) showed positive skin test and 108 of 260 older children with asthma (41.5%) were positive for the skin tests; total positive rate was 42.61%.

结果 经1年的调查，曝片观察到的35 746个真菌孢子和曝皿观察到的1 188个菌落，分属于4个亚门60个种属，常见菌种有黑粉菌、交链孢菌、锈菌、枝孢芽枝菌、芽枝菌、皮思菌、大孢枝孢菌、黑曲菌、杂曲菌和烟曲菌。85例婴幼儿哮喘患儿，39例真菌变应原皮内试验阳性（45.9％），260例儿童哮喘患儿，108例皮试阳性（41.5％），总阳性率42.6％。

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
