Einfluss einer Belastung mit bodenbürtigen Schaderregern auf bunt- und weißblühende Erbsen in einem Gefäßversuch

Summary in the original language of the document

Generally, purple-flowered peas are assumed to be less susceptible to soilborne pests. The above- and belowground biomass yield of one purple-flowered and one white-flowered pea were compared on three soils with and without soil fatigue.
Both peas showed lower above- and belowground biomass yield on soil fatigue soils than on unstressed soils. The aboveground yield´s decrease of the purple-flowered pea was higher than for white-flowered pea on two of the three soils. Hence, purple-flowered peas are generally not less susceptible to soilborne pests than white-flowered peas.
