Influence of the environment on development and sex differentiation of root-knot nematodes

Abstract

The rate of development of Meloidogyne incognita was retarded in tomato plants subjected to deficiency treatments of -N, -P, -K, -N-P, -N-K, -P-K, and -N-P-K compared to plants receiving complete (NPK) nutrient. The percent of males was higher in all deficiency treatments but the differences were not very striking since male percentage was relatively low (below 10) in all cases. In most deficiency treatments, roots of infected plants showed higher concentrations of N, Ca and Mg than roots of noninfected plants of the same treatments. Also, with some exceptions, P concentration was higher and K concentration was lower in nematode infected plants. © 1967 BRILL.
