Biodiversity effects on grape quality depend on variety and management intensity

Steiner, Magdalena ; Grace, James B. ; Bacher, Sven

In: Journal of Applied Ecology, 2021, p. 1-13

1. Interactions between plants can be beneficial, detrimental or neutral. In agricultural systems, competition between crop and spontaneous vegetation is a major concern. We evaluated the relative support for three non-exclusive ecological hypotheses about interactions between crop and spontaneous plants based on competition, complementarity or facilitation. 2. The study was conducted in...

Vionnet, Léo ; Vrieze, Mout De ; Dutartre, Agnès ; Gfeller, Aurélie ; Lüthi, Angelika ; L’Haridon, Floriane ; Weisskopf, Laure

Recent studies have shown that plants harbor complex bacterial communities, the so- called “microbiome”. We are only beginning to unravel the origin of these bacterial plant inhabitants, their community structure and their roles, which, in analogy to the gut microbiome, are likely to be of essential nature. The aim of this work was to analyze the abundance and diversity of the cultivable...
