摘要

Investigations were conducted here to determine the effect of a magnetic field on the ripening of green tomatoes (Lycopersicon esculentum Mill. Var. V. R. Moscow). Four permanent magnets of considerable strength were utilized. Fruits of uniform maturity were placed between the magnetic poles ... The ripening rates of treated fruits were compared with those of untreated controls in the same room under similar conditions ... In all cases the treated fruits ripened faster than the controls. Furthermore, the fruits nearest the magnetic south ripened faster than those nearest the magnetic north.
