Globodera rostochiensis Population Density Decline in Relation to Spatial Distribution around Resistant Potato Plants.
Golden nematode, Globodera rostochiensis (GN) population decline under resistant potatoes was related to cyst distance from plants 23 cm apart in rows 92 cm apart. GN decline, determined by sampling an infested field planted to the resistant cultivar 'Yankee Chipper', was 81.8% in cores 11.5 cm from plants within rows. Decline was 27.4% at 23 cm from plants between rows and 36.6% at 46 cm. Popu...
متن کاملRoot Growth of Susceptible and Resistant Potato Cultivars and Population Dynamics of Globodera rostochiensis in the Field.
Globodera rostochiensis population densities and potato root growth were measured in field plots of one susceptible and two resistant potato cultivars. Root growth and nematode densities were estimated from soil samples taken at three depths between plants within the rows, three depths 22.5 cm from the rows, and at two depths midway between rows (furrows). Four weeks after plant emergence (AE),...

متن کاملEarly responses of resistant and susceptible potato roots during invasion by the potato cyst nematode Globodera rostochiensis.
Signals from roots of resistant (cv. Maris Piper) and susceptible (cv. Désirée) potato cultivars during invasion by second stage juveniles (J2s) of the potato cyst nematode, Globodera rostochiensis, were investigated. Novel experimental chambers enabled the recording of electrophysiological responses from roots during nematode invasion. The root cell membrane potentials were maintained througho...
متن کاملBrassinosteroid-mediated Changes in Root-knot Nematode Susceptible and Resistant Tomato Cultivars
Plant-parasitic nematodes are one of the major pests, causing damage to almost all cultivated crops throughout the world. Present nematode control measures pose a threat to the environment; therefore, use of natural compounds is being emphasized to control these deterrents. 28-Homobrassinolide (HBl) is one such naturally synthesized compound that is ubiquitously distributed in plant kingdom. In...
