缺少筛选和评定的简单方法影响了慢锈性的选择。在田间测定大量的接种体和严重的病害会掩盖慢锈性。在小区中,当接种体从临近种植的速锈品种上吹来时慢锈性可能会被低估。成株在室内测定是麻烦的,一来空间有限,二来要给大量植株均匀接种也是困难的。采用离体叶片的方法对初测是有用的,但离体叶片比原株的叶片更易感病。
The lack of screening and assessment of the simple method of affecting the choice of slow rust. Determining a large number of inoculum and serious diseases in the field can mask slow rust. In communities, the slow rust may be underestimated when the inoculum is blown from the near-planted varieties of rust. Adult determination in the interior is cumbersome, one to space is limited, and secondly to give a large number of plants evenly inoculated is also difficult. The method of using isolated leaves is useful for the first test, but leaves of isolated plants are more susceptible than the leaves of the original plants.
