Influence of moisture on maturation rate of the airborne Venturia inaequalis (Cooke) Wint. ascospores was numerically examined using field data collected from spore traps in Skierniewice, Poland, during 2005–2008 and 2010–2014. In order to avoid a bias resulting from different abundance of airborne ascospores in different seasons, the cumulative proportions of mature ascospores observed in the season were analyzed. The maturation rate was expressed with the probit of cumulative proportion which linearized its sigmoidal shape and made the effect of the weather during the entire season of the same importance. The significant, positive association between the probit slope and the moisture indicators related to precipitation, leaf wetness, and high relative humidity were observed. Additionally, the significant, negative relationships with the average and maximal air temperature were found. The results suggested that rain should be treated as the major factor driving the ascospore development and leaf wetness as the second factor. In conclusion, the main sources of moisture should be taken into account in statistical models of ascospore development, but it seems reasonable to take into account different strength of their association with the development rate.

水分对Venturia inaequalis（Cooke）Wint成熟速率的影响。波兰中部的子囊孢子

水分对机载Venturia inaequalis成熟率的影响（可乐）温特。在2005-2008年和2010-2014年期间，使用从波兰Skierniewice的孢子阱收集的田间数据对孢子孢子进行了数值检查。为了避免由于不同季节的空中子孢子的丰度不同而引起的偏差，分析了在该季节中观察到的成熟子孢子的累积比例。成熟率用累积比例的概率表示，其线性化其S形并使得整个季节的天气影响同样重要。观察到概率斜率与与降水，叶片湿度和高相对湿度有关的湿度指标之间存在显着的正相关关系。此外，还发现与平均和最高气温之间存在显着的负相关关系。结果表明，应将雨水作为驱动子囊孢子发育的主要因素，而将叶片湿度作为第二个因素。总之，在子囊孢子发育的统计模型中应考虑水分的主要来源，但考虑到它们与发育速率的关系的不同强度似乎是合理的。
