高粱、玉米丝黑穗菌[Sphacelotheca reiliana (Kuhn)Clint.]是否有生理分化现象,两者间能否相互侵染,目前的结论尚不一致。据Al-Sohaily和Mankin,Al-Sohaily、Mankin和Semeniuk,Bressman和Barss、Reed报告,玉米丝黑穗菌不能侵染高梁,而Reed、Swabey和Kolk的结果是两种作物上的丝黑穗菌可以互相侵染。为肯定两者间相互侵染关系,1962—1963年进行了交互接种试验。所用高粱品种1962年为“老母猪跷脚”,1963年为“护2号”,玉米品种为“82号”。丝黑穗菌1962年春分别从高粱、玉米稭上收集的;1963年均是从1962年田间交互接种发病后,为防止污染,于刚抽出黑穗尚未破裂前用厚纸套袋,分别
Sorghum, Sphacelotheca reiliana (Kuhn) Clint.] Are physiologically differentiated and their interaction with each other. The current conclusions are not consistent. According to Al-Sohaily and Mankin, Al-Sohaily, Mankin and Semeniuk, Bressman and Barss, Reed reported that maize stinkbugs can not infect sorghum, whereas the results of Reed, Swabey and Kolk are both of the two crops, Can infect each other. In order to affirm the mutual infection between the two, 1962-1963 conducted an interactive vaccination trial. Sorghum varieties used in 1962 as “sow legs”, 1963 “protect the No. 2”, corn varieties “No. 82.” Smilax was collected from sorghum and corn stalks respectively in the spring of 1962. In 1963, all were from the field vaccination in 1962 to prevent pollution. Before the black spikes were removed,
