Pre-sowing seed treatments improve the germination and the growth of pepper and tomato seedlings

The aim of a recent conducted study was to establish the effect of different seed treatments on germination, and the growth of the embryonic stem and the radicle of tomato and pepper varieties. Four treatments were used in the study: MIX [(Coveron + zinc (Zn 0.5%) + boron (B 0.025%)]; Coveron; zinc (ZnSO4, Zn 0.5%) and boron (B 0.025%). The treatments were applied on seeds of following four pepper varieties: Šorokšari, Somborka, Kraljica, and Mirtima and three tomato varieties: Rio Grande, Saint Pierre, and Tomato apple of Novi Sad (Novosadski jabučar).

Germination and the growth increase of both the embryonic stem (cm) and the radicle (cm) were observed in the germination cabinets and pots containing soil in two laboratories – locations. After the treatment applied to the pepper seeds and testing in the laboratory germination cabinet the following was established: i) the maximum increase in germination of 90% was when the MIX and Zn treatment was applied to seeds, ii) the growth increase of embryonic stems of 2.7 cm was recorded when the MIX treatment was applied, iii) the growth increase of radicles of 1.7 cm was gained when the Coveron and MIX treatment was applied.

Tests performed in pots showed that Coveron was the most efficient treatment. Treatments on tomato seeds during the seed testing in the germination cabinet provided: vi) the germination increase of 13% with the MIX treatment, vii) the growth increase of the embryonic stem of 2.6 cm with the same treatment, vii) the growth increase of 1.7 cm of radicles. Coveron was the most efficient treatment in tests in pots. Key words: coveron, seed quality, micronutrients, growth of embryonic stem and radicle.
