SUMMARY Oat seedlings were grown in Sand, a third of the plants were inoculated with second-stage juveniles of H. auenae. Plants were transferred to hydroponic culture where lengths of seminal root axes, without nematodes or with established 53 H. avenue, were Iabelled with 45Ca+*. Translocation of calcium to the shoots was eleven times greater from the labelled nematode infected roots than from the labelled uninfected roots. Histological examination showed nematodes caused major disruption of… Expand

Foliar calcium concentration of potato and its relation to genotype lateness and tolerance of cyst nematodes
TLDR
The relationship between tolerance and calcium contents was clearest when sampling took place towards the end of the growing season when the variability was at it highest with a good distinction between newly formed leaves in late maturing genotypes and aged leaves in early maturing cultivars. Expand
The effects of fertilisers, particularly foliar applied, on the potato plant's tolerance of attack by the potato cystnematodes, Globodera rostochiensis and G. pallida
TLDR
It is suggested that foliar nutrient applications can benefit the growth, yield and tolerance of PCN-infected plants, but that plant tolerance may benefit further if nutrient applications match the requirements of the plant as shown by plant nutrient analyses. Expand
Pest aspects of potato production
Plant-parasitic nematodes are typically small (0.2–10 mm long) worm-like animals, able to move between soil particles, between folded leaves of plant buds, in the air spaces of leaves and stems or inExpand
Growth, water uptake and calcium content of potato cultivars in relation to tolerance of cyst nematodes
SUMMARY The growth of early maturing potato cultivars was more affected by nematode infection than that of late maturing cultivars and al1 infected plants contained a greater proportion of dry matterExpand
The phenology of plant-nematode interaction and yield loss
TLDR
The present estimates and determinations of crop loss from any given factor leave much to be desired and are best described by the following quote. Expand
Resistance to and Tolerance of Plant Parasitic Nematodes in Plants
TLDR
The purpose of this review is to outline the mechanisms and principles governing nematodelplant interactions and to consider some of the useful parallels between nematodes and other plant pathogens, especially fungi. Expand
Pathogenicity and reproduction of Meloidogyne incognita (Kofoid and White) chitwood on African yam bean, Sphenostylis stenocarpa (Hochst Ex. A. Rich) Harms accessions
TLDR
Results showed that growth, yield and yield parameters were significantly reduced in inoculated accessions when compared with the controls, and the tolerant accessions are recommended for use by African yam bean farmers as they would check yield losses caused by M. incognita. Expand
How Plants Affect Nematodes
TLDR
The chapter concludes that the poorly defined feeding habits of nematodes, the absence of distinct trophic levels, the increase in quality or information content of food with progression from the autotroph, and stimulation of prey species by grazers or predators, their populations are worthy of study. Expand
Effects of Globodera rostochiensis and water stress on shoot and root growth and nutrient uptake of potatoes
TLDR
Nematode infection and water stress resulted in decreased tuber production, especially in combination; total P, K and Mg uptakes were also decreased. Expand
Effect of Meloidogyne incognita on Plant Nutrient Concentration and Its Influence on the Physiology of Beans.
TLDR
One of the first effects of the nematode on host physiology appears to be a change in concentration of nutrient elements in the host plant, which significantly decreased with level of infection. Expand

Tolerance of potato to potato cyst nematodes (Globodera rostochiensis and G. pallida) in relation to the growth and efficiency of the root system
TLDR
Cultivars tolerant of potato cyst-nematode (PCN) differed from intolerant cultivars in that their root systems tended to grow larger in heavily infested soil than in lightly infested or nematicide-treated soil, so partly compensating for the reduction in the top/root ratio. Expand
Tolerance to cyst-nematode attack in commercial potato cultivars and some possible mechanisms for its operation
TLDR
The degree of tolerance to nematode attack was related to the amount of calcium accumulated in the dry matter of plants growing on the uninfested site and this relationship may have been due to the efficiency with which different cultivars used water. Expand
Effects of Potato Cyst-Nematodes On Potato Plants
TLDR
Final yields were decreased by nematode-infested plants because infested plants were smaller and because they senesced earlier than plants infested with few nematodes. Expand
Root and Cell Response To Feeding By Xiphinema Index
TLDR
Feeding was observed and examined on seedlings of Ficus carica and Lycopersicon esculentum under gnotobiotic conditions in agar culture and modified cells, induced under aseptic conditions, appeared to be a precondition for a successful host-parasite relationship. Expand
Water Uptake by Different Regions of the Barley Root. Pathways of Radial Flow in Relation to Development of the Endodermis
TLDR
The response to the increased transpirational demand is met by the older regions of the root, in particular by the zone of lateral emergence where an apoplastic pathway is known to exist as the Casparian band in the endodermis breaks down with the emergence of the lateral roots. Expand
A comparison of some quantitative methods of extracting small vermiform nematodes from soil
TLDR
This sedimentation method extracted as many nematodes from sand and loam as Seinhorst's two-flask and elutriation methods, but in one test extracted fewer Tylenchorhynchus from clay and in another fewer Paratylenchus from Clay than the elutRIation method. Expand
PROPERTIES OF ROOTS WHICH INFLUENCE RATES OF ABSORPTION
Summary A review is given of some of the structural and physiological factors which control the radial flow of nutrient ions and water across the root to the xylem. Consideration is given to theExpand

A fluidising column for extracting nematodes from soil
TLDR
An apparatus which uses a controlled water current passing through a sintered plate to separate nematodes from soil particles is described, and it may prove useful for extracting other small soil invertebrates, or their eggs. Expand
