桃树品种雷德海文和洛林的果实从6月上旬开始每周采收一次，一直持续到完全成熟，然后在控制的条件下接种果色假单胞菌103-106孢子/毫升。在这两年的研究中，果实在6月的2-3周内在所有接种剂浓度下都是敏感的。在坑硬化时，它们对所有接种物浓度的感染都具有抵抗力。果实在完全成熟前大约2周左右再次变得越来越容易受到感染。
Peach [Prunus persica] fruits of the cultivars Redhaven and Loring were harvested weekly beginning in early June and continuing to full ripeness, and were inoculated under controlled conditions with Monilinia fructicola at a range of 103-106 conidia/ml. In both years of the study, fruits were susceptible to infection at all inoculum concentrations for 2 to 3 wk in June. At pit hardening they became resistant to infection at all the inoculum concentrations. Fruits again became increasingly susceptible to infection approximately 2 wk before full ripeness.
