1957—1959年以麦角菌Claviceps microcephala (Walir.)Tul.的Ce5,Ce5-29-1及Ce5-35-1等3个优良菌系分別在大麦、小麦及黑麦等的23个品种上进行了接种栽培。 Ce5菌系在不同麦类上有很强的寄生力,在三种麦类上的穗寄生率,黑麦类較大麦及小麦高,且感染力也强,在黑麦类中冬黑麦又比春黑麦易于感染,三种麦类所产麦角千粒重以黑麦类为高,大麦类及小麦类为低。其麦角千粒重分别为37—76克,25—44克及21—34克。 Ce5菌系在不同麦类上所产麦角的含碱量为0.078—0.4％,其中以裸大麦麦角含碱量最高,达0.4％。Ce5-29-1及Ce5-35-3菌系,无論从寄生性或是产碱能力方面来看均不次于原菌系Ce5。白麦角变异菌系Ce5-W亦有較强的寄生性,并可产生一定量的麦角碱。經分析証实Ce5及Ce5-29-1 2个菌系在不同黑麦品种上所形成的麦角中含有极有价值的麦角新碱,其含量分別为0.029—0.036％及0.042％。黑麦麦角菌Claviceps purpurea (Fr.) Tul.的Sc-2-4,Sc-6-2及Sc9-5 3个菌系分別接种在张北等5种黑麦上,其穗寄生率达48—98％;其麦角碱含量最高者不超过0.015％或不含麦角碱。
From 1957 to 1959, three fine strains of Ce5, Ce5-29-1, and Ce5-35-1 of Claviceps microcephala (Walir.) Tul. were carried out on 23 varieties of barley, wheat, and rye. Inoculated cultivation. The Ce5 strain has strong parasitic power in different wheat species, and its ear parasitism rate in three kinds of wheat, high wheat in rye and wheat is high, and the infectivity is also strong, and winter rye in rye Spring rye is prone to infection. Three rye ryegrasses are produced from rye, and barley and wheat are low. The weight of its ergot is 37-76 grams, 25-44 grams and 21-34 grams, respectively. The alkali content of ergots produced by Ce5 strains in different wheat varieties was 0.078-0.4%, of which barley groats contained the highest alkali content, up to 0.4%. The Ce5-29-1 and Ce5-35-3 strains are not inferior to the original strain Ce5 in terms of their parasitic or alkali-producing ability. White ergot variant strain Ce5-W is also highly parasitic and can produce a certain amount of ergot alkaloids. The analysis confirmed that the two strains of Ce5 and Ce5-29-1 contained extremely valuable ergometrine in ergots formed on different varieties of rye, and their contents were 0.029-0.036% and 0.042%, respectively. Three strains of Sc-2-4, Sc-6-2, and Sc9-5 of Lactobacillus Claviceps purpurea (Fr.) Tul. were inoculated on 5 kinds of rye, such as Zhangbei, and their ear parasitism rate reached 48. -98%; the highest content of ergot alkaloids does not exceed 0.015% or does not contain ergot alkaloids.
