小麦品种抗銹性的研究,是研究防治小麦锈病措施中的一項經济有效的根本措施。根据几年来我們在这方面的工作体会,参考目前各地的一些資料,試就小麦品种抗銹性的鉴定方法,綜合介紹如下。一、孢子悬浮液的配制孢子悬浮液有清水孢子悬浮液和洋菜胶孢子悬浮液两种。清水孢子悬浮液,是用接种針(一端为盾状扁平的普通鉄針)直接挑取銹菌夏孢子,置于清水中配制而成;洋菜胶孢子悬浮液,是用一千份水比一份洋菜(琼脂),經加热熔化成均匀的洋菜胶溶液,而后再以接种針挑取銹菌夏孢子,置于其中配制即成。这两种孢子液均經常采用。前一种虽配制方法簡便,但孢子悬浮性不好,多浮在水 The study on the rust resistance of wheat cultivars is a cost-effective and fundamental measure to control wheat rust. According to the past few years we work experience in this regard, with reference to some of the information around the current test on the identification of wheat varieties rust resistance, a comprehensive introduction is as follows. First, the preparation of spore suspension spore suspension with water spore suspension and agar spore suspension two. Water spore suspension, is the inoculation needle (one end of the shield-shaped flat needle commonly used) directly pick rust summer spores, placed in clear water preparation; Agar Spore suspension, with a water ratio of one thousand An agar (Agar), heated to melt into a uniform Agar solution, and then pick the needle to pick rust rust spores, placed in which Serve. Both spore liquid are often used. Although the first preparation method is simple, but poor suspension of spores, more floating in water
