Quantification of <i>Colletotrichum fioriniae</i> in Orchards and Deciduous Forests Indicates It Is Primarily a Leaf Endophyte

چکیده
Colletotrichum fioriniae of the C. acutatum species complex is an important hemibiotrophic pathogen vegetables and fruits in temperate regions worldwide. In apple, it one primary responsible for bitter rot disease. Understanding disease cycle complicated because many broadleaf plants can be hosts fioriniae. By detecting quantifying rain-splashed conidia more than 500 samples from heavily bitter-rot-infected apple orchards nearby forested woodlots over two summers, we show that conidial quantities were higher orchards. Testing 1,000 surface-disinfected leaves 24 different forest plant showed overall was abundant leaf endophyte, with high variation colonization area. Endophytic isolates pathogenic on apples, multilocus sequence analysis 100% identity between most diseased fruits. Apple endophytically infected present a conventionally managed orchard untreated orchard. These lines evidence, context previously published research, lead us to hypothesize main ecological role which as generalized infection provides updated framework its integrated management agricultural systems.

It is widely accepted that nitrogen limits primary production in temperate forests, although co-limitation by N and P has also been suggested, and on some soils Ca and base cations are in short supply. I conducted a meta-analysis to assess the strength of existing experimental evidence for limitation of primary production by N, P, and Ca in hardwood forests of the northeastern United States and...

Leaf area index (LAI) is an important structural characteristic of forest ecosystems which has been shown to be strongly related to forest mass and energy cycles and forest productivity. LAI is more easily measured than forest productivity, and so a strong relationship between LAI and productivity would be a valuable tool in forest management. While a linear relationship has been observed betwe...
