  title={Effect of Root-Knot Nematodes On the Mineral, Amino Acid and Carbohydrate Concentrations of Almond and Peach Rootstocks},
  author={T. A. A. Nasr and I. K. A. Ibrahim and Esraa M. El-Azab and M. H. A. Hassan},
The mineral concentrations of both roots and leaves of bitter almond were significantly greater in plants infested by Meloidogyne javanica or M. incognita than in uninfested plants. K, Ca, Mn and Cu concentrations of roots and leaves were increased; P concentrations of leaves and N concentrations of roots were also increased. The concentration of Fe was significantly decreased whereas those of Mg and Zn were unaffected. There were no significant differences in mineral concentrations of roots or… 
Effect of root-knot nematode Meloidogyne incognita on the total protein, carbohydrate and lipid in roots at different growth stages of Hibiscus esculentus
The root-carbohydrate and root-lipid, which are thought to be reduced due to feeding by nematode, provide additional biochemical parameters for evaluating the intensity of infection with root-knot nematodes.
Impact of Organic and Inorganic Fertilizers on Nematode Reproduction and Biochemical Alterations on Tomato
The organic amendments, compost, neem and poultry as well as inorganic fertilizer, N P K and nematicide Nemacur 10% G applied singly at two different doses were effective in reducing M. incognita
Effect of Meloidogyne incognita on Plant Nutrient Concentration and Its Influence on the Physiology of Beans.
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.
Impact Of Nematode Infestation on Nutritional Quality of Some Underground Vegetables in Pakistan
Data indicates that highest reproduction rate and rootknot index was observed in vegetable plants infected with root-knot nematodes after three months as compared to un-infected (control).
Physiological Response of Resistant and Susceptible Vitis vinifiera Cultivars to Meloidogyne incognita.
Nematode stress dosage, measured as the product of cumulative number of juveniles and females and their total energy (calories) demand, accounted for up to 15 and 10% of the energy assimilated by French Colombard and Thompson Seedless plants, respectively, suggesting that the resistant cultivar may be using more energy to curtail the nematode's activity.
Effect of Meloidogyne incognita on bio-chemical changes in leaves of Mentha arvensis
Meloidogyne incognita inoculum @1000J2/ /pot and above significantly affected the quality of mint oil and significantly reduced the menthol per-cent in mint oil, which is the basis of price fixation in market.
Variation in nutrient status of susceptible and resistant bitter gourd varieties infected by root knot nematode, Meloidogyne incognita
Six varieties of bitter gourd genotypes/ seeds were collected and screened under greenhouse condition for both susceptibility and biochemical reactions to root-knot nematode (RKN) Meloidogyne incognita and significant increase of potassium content of both susceptible and resistant infected plants was observed.
The Role of Manganese in Resistance to Plant Diseases
The generally adequate availability of most nutrients for plant growth has induced an apathetic attitude toward the vital role of minerals in disease resistance, especially for Mn which has received most attention because of its potential toxicity.
Carbohydrate Concentration in Pine as Affected by Inoculation with Bursaphelenchus xylophilus.
Pines responded to inoculation with Bursaphelenchus xylophilus by changes in reducing and nonreducing carbohydrate concentrations dependent on the pine species and the pathotype of B. xylophilus with
