Influence of storing seeds on seed vigor and seedling meadow and tall fescue after five years

Abstract

In our tests, the seeds were stored for five years at temperatures of 4 °C, 18 °C in a warehouse conditions (factor method of seed storage). Seed was stored at all temperatures in the paper, a cloth and plastic bags (factor package for seed storage). It was used the seed of meadow and tall fescue (factor species). For testing was used the three lots by both species (factor seed lots). At five years old seed germination was determined in accordance with the ISTA rules (on filter paper, and at temperature of 20 °C in the dark). Vigor was determined by measuring each seedling (root length cm, shoot length cm and biomass of seedlings g.). The factor method of seed storage and packaging factor was significantly acted in germination and vigor (P lt 0.05, P lt 0.01), which influenced to meet germination of seeds for placing on the market (germination gt 75 %). Other examined factors (species and lots) did not have significant effect on seed germination and seedling vigor after five years of storage.

Livadski vijuk (Festuca pratensis Huds.) je značajna krmna vrsta koja se koristi uglavnom za smeše sa višegodišnjim krmnim leguminozama. Visoki vijuk je (Festuca arundinacea Schreb.) je vrsta koja je veoma srodna livadskom vijuku koja se pored korišćenja sa krmnim leguminozama za proizvodnju kvalitetne krme, koristi i za zasnivanje travnjaka specijalnih namena takođe uglavnom u smeši sa odgovarajućim višegodišnjim leguminozama (parkovi, sportcki tereni, okućnice i sl.). U našim ispitivanjima seme je čuvano pet godina na temperaturama: 4oC, 18oC i u magacinskim uslovima (faktor način čuvanja semena). Seme je na svim temperaturama čuvano u papirnim, platnenim i plastičnim kesama (faktor anbalaža za čuvanje semena). Za ispitivanje je korišćeno seme po tri partije (faktor partija semena) od ispitivanih vrsta: livadckog, i visokog vijuka (faktot vrsta). Faktori način čuvanja semena, anbalaža u kojoj je seme čuvano i, vrsta kao i nihove interakcije su delovali značajno na klijavost i vigor klijanaca (P≤ 0,05, P≤ 0,01) što je i uticalo na zadovoljenje klijavosti za stavljanje semena u promet (klijavost gt 75%). Ostali, ispitivani faktor (partija) nije imao značajnog uticaja na klijavost semena i vigor klijanaca nakon pet godina čuvanja.
