Effect of Se on the host­-parasite system – tomatoes cv. Tiny Tim – Meloidogyne arenaria was studied. Seeds of tomatoes were moistened in water colloid solution of Se (nano solution) in concentration of  0.336 mg per L for 2 h. During the period of two months the development of the plants as well as the development of M. arenaria  were observed. The following parameters of the plants and the parasite were measured: 1. Period for development of one M. arenaria generation; 2. Size of females; 3. Gall formation on the roots (after Barker,1985); 4. Plants height; 5. Fresh weight of the plants; 6. Size and fresh weight of the fruits. The positive effect after treatment with Se on the invasion of the plants was statistically proved. On the base of our experiments the changes of M. arenaria morphologic characteristics and  the normal development of the plants can be explain through the effect of Se treatment on the plants–improvement of some plant innate mechanisms to Meloidogyne invasion.

Key words: Meloidogyne arenaria; invasion; Se (nano solution); tomatoes; development; plants
