Abstract

The substrate of different composition, prepared on the basis of domestic raw materials and their impact on the development of seedlings of flower CatharanthusroseusL. were researched.
The selection of species was made according to the length of the vegetation (10-14 weeks) of seedlings as well as on the basis of their presence in the product assortment of producers in Serbia. The production of the initial seedling was carried out by means of speedling system in plastic containers, and further growing was resumed after transplanting in pots and on substrata made of Tutun peat, zeoplant and perlitof 7 different composition.

It has been determined that tested substrata, regarding their physical and agrochemical properties are favourable for growing seedlings of Catharanthusroseus. The development of obtained seedlings (plant height, above-ground mass, root shoot ratio) on the substrata comprising zeoplant, was better than the development achieved on ready-made-commercial substratum.

The best development of plants-seedlings Catharanthusroseus Pacifica - red on the substratum 3, T80+P10+Z10.
