1972年进行了蚕豆灰霉病菌侵染对蚕豆生长和产量的影响试验，定期连续取样，记录寄主的生长和病情进展。生长分析表明，蚕豆上的蚕豆灰霉病菌对蚕豆的主要影响是降低叶面积比，并通过增加净同化率来补偿，因为相对生长速率没有下降。健康植株的产量比患病植株平均高出27%。对产量构成因素的分析表明，产量的损失完全是由于单株角果数减少所致，由此得出结论，巧克力斑点病对生长的生殖方面的影响最大。
SummaryA trial was conducted in 1972 to assess the effect of Botrytis fabae Sard, (chocolate spot) infection on the growth and yield of broad bean ( Vicia faba L.), by sequential sampling at regular intervals to record the growth of the host and the progress of the disease.Growth analysis indicated that the major effect of B. fabae on broad beans was to reduce the leaf area ratio, which was compensated by an increased net assimilation rate, since there was no drop in relative growth rate. The healthy plants outyielded the diseased plants by an average of 27 %. Analysis of the components of yield indicated that the loss in yield was due solely to a decreased number of pods per plant, from which it was concluded that the most damaging effect of chocolate spot infection was on the reproductive aspects of growth.
