Influence of storage conditions and seed treatment on germination energy and seed germination of maize hybrids

Abstract

After seed processing of OS maize hybrids (Ossk 430, Ossk 499, Ossk 602 and Ossk 617) 500 kg of seed was taken from each hybrid and treated in mobile sprayer in the following treatment variances: T-1 (A.I. carboxine+tiram, dosage 500 ml/100 kg of seed), T2 (A.I. fludioxonyl+M-metalaxyl, dosage 100ml/100kg of seed), T-3 (A.I. carboxin+tiram, dosage 500ml/100kg of seed + A.I. imidacloprid, dosage 0,6l/100 kg of seed). After the treatment seed was packed into PWC bags and from each treatment seed samples were made for concrete, floor storage (S-1) and concrete floor storage with termoisolation (S-2). Germination energy and seed germination of all variances of seed treatment were determined at the beginning of storaging (C-1), after 12 months of storaging (C-2) and after 24 months of storaging (C-3). The highest germination energy and seed germination were with seed of hybrids OSSK 499 and OSSK 430,while hybrids OSSK 602 and OSSK 617in all seed treatments had lower germination energy (4-7%) and seed germination (3-5%). Seeds of maize hybrids which were storaged into floor concrete storage with termoisolation in conditions of lower temperature and relative air humidity had better quality compared to seed storaged into floor concerete storage. Research results show significance of storage treatment, storage conditions and hybrids on germination energy and seed germination during storaging of 24 months (P<0,001).
