RIPRODUZIONE DI HETERODERA SCHACHTII SU PIANTE COLTIVATE (2° CONTRIBUTO)

Abstract

Prove, condotte in amiente controllato, in terreno infestato da Heterodera schachtii hanno indicato che fava (cvv. Aquadulce supersimonia e Botana), pomodoro (cv. C 37) e trifoglio bianco (cv. Cece bianco), pisello odoroso, pisello (cv. CH 17), pomodoro (cv. Red-setter), rafano oleifero (cv. Levana), soia (cv. Futura), trifoglio resupinato, veccia vellutata, melanzana (cv. Violetta lunga) e trifoglio rosso (cv. Viola). Egrave; risultata, invece, pianta suscettibile il fagiolo (cv. Borlotto nano 45) e piante molto suscettibili il fagiolo (cv. Taylor Hort. Normale) e il pisello (cv. Perfection) e fortemente suscettibili il garofano (cv. Miscuglio Chabaud) e la barbabietola da zucchero. [Experiments carried out under controlled conditions in soil infested by Heterodera schachtii indicated that broadbean (cvs Aquadulce supersimonia and Botana), tomato (cv. C 37) and white-clover (cv. Huia) are not susceptible to the nematode. Conversely chick pea (cv. Cece bianco), sweet pea, pea (cv. CH 17), tomato (cv. Red setter), oil radish (cv. Levana), soybean (cv. Futura), reversed clover, hairy vetch, eggplant (cv. Violetta lunga) and red clover (cv. Viola) showed little evidence of susceptibility. Bean (cv. Borlotto mano 45) was moderately susceptible and bean (cv. Taylor Hort. Normale) and pea (cv. Perfection) were very susceptible. Carnation (cv. Miscuglio Chabaud) and sugarbeet were highly susceptible.]
