为了查明一年生黑麦草的毒素发育及其与植株生长发育的关系,作者于1981年在澳大利亚西部的卡塔宁附近进行了田间小区试验。通过把菌瘿与野麦草种子混拌对土壤接种。在植株开花始(9.22日)每隔1周收获一次,共10次。各收获期测定植株发育时期,开花数和菌瘿数。野麦草植株地上部毒素含量是用细菌抑制生物测定法测定的。结果表明,开花前和开花期每平方米野麦草中的毒

In order to ascertain the toxin development of annual ryegrass and its relationship with plant growth and development, the author conducted field trials in 1981 in Katanin, western Australia. Inoculate the soil by mixing it with grass seeds. The plants were harvested once every other week from the beginning of flowering (9.22 days) for 10 times. Each harvest period determination of plant development period, the number of flowering and mycelium number. The shoot toxin content of the wheatgrass plants was determined by bacterial inhibition bioassay. The results showed that the toxicity of wheat grass per square meter before flowering and anthesis
