ABSTRACT A survey was conducted over a 3-year period to determine the frequencies and distributions of fruit-rotting fungi in New Jersey cranberry beds. In the first 2 years of the study, Physalospora vaccinii and Glomerella cingulata were the most prevalent and widespread field-rotting fungi. In the third year, the frequency of G. cingulata declined markedly. Other species such as Coleophoma empetri, Phyllosticta vaccinii, and Phomopsis vaccinii were isolated at high frequencies from a limited number of locations. Storage-rotting fungi including Allantophomopsis cytisporea and A. lycopodina were isolated at low frequencies, but were widely distributed within the growing region. On sound fruit, a somewhat different profile emerged. Fungi such as Phyllosticta elongata, Alternaria spp., and Physalospora vaccinii were commonly isolated. In comparisons among different cranberry cultivars, no differences in the fungal profiles were seen. This was interpreted to indicate that if differences in fruit-rot resistance exist, they are likely to be general forms of resistance rather than fungal species-specific mechanisms.
摘要 在 3 年的时间里进行了一项调查，以确定新泽西蔓越莓床上果实腐烂真菌的频率和分布。在研究的头两年，Physalospora vaccinii 和 Glomerella cingulata 是最普遍和广泛分布的田间腐烂真菌。第三年，G. cingulata 的频率显著下降。其他物种，如 Coleophoma empetri、Phyllosticta vaccinii 和 Phomopsis vaccinii，从少数几个地方以高频率分离出来。贮藏腐烂真菌，包括 Allantophomopsis cytisporea 和 A. lycopodina，分离频率较低，但在生长区域内广泛分布。在健康的果实上，出现了一个略有不同的情况。Phyllosticta elongata、Alternaria spp. 和 Physalospora vaccinii 等真菌通常被分离出来。在不同蔓越莓品种之间的比较中，真菌的特征没有差异。这表明，如果果实腐烂抗性存在差异，它们可能是一般形式的抗性，而不是真菌物种特异性的机制。
