Cilj istraživanja je uticaj različitih temperaturnih uslova na klijanje semena
suncokreta (Helianthus annuus) izvedenih u laboratorijskim uslovima u toku 2007. godine. U
ovom radu korišćena su četri francuska hibrida suncokreta: Alvaro RM (veoma rani do rani),
Altesse RM (rani do srednje rani), Alium (srednje rani) i Albatre (srednje rani do srednje
kasni). Istraživanja su rađena prema domaćem Pravilniku o kvalitetu semena poljoprivrednog
bilja i međunarodnim ISTA Pravilima, tačnije korišćena je standardna metoda između filter
papira na tri temperature: naizmenična 20-30oC, konstantna 20oC i konstantna 25oC. Prema
dobijenim rezultatima Alvaro RM ima najbolju energiju klijanja na 20oC, a ukupnu klijavost
na 25oC. Altesse RM ima najbolju energiju klijanja i ukupnu klijavost na 25oC, dok druga dva
hibrida Alium i Albatre imaju najbolju energiju i ukupnu klijavost na naizmeničnoj
temperaturi 20-30oC. Rezultati ovog istraživanja pokazali su da ispitivani hibridi suncokreta
imaju ...različite tempetrature energije klijanja i ukupne klijavosti.
The aim of the present study, carried out in the laboratory in 2007, was to
observe effects of different temperature conditions on sunflower (Helianthus annuus)
seed germination. The four French hybrids Alvaro RM (very early to early), Altesse
RM (early to medium early), Alium (medium early) and Albatre (medium early to
medium late) were used as a material in this study. The investigations were
performed according to the National Regulations of Seed Quality of Agricultural
Plants and the international ISTA Rules, to be more accurate, a standard filter paper
method at three temperatures was used: alternating temperature of 20-30oC, constant
temperature of 20oC and constant temperature of 25oC. According to obtained results
the hybrid Alvaro RM had the best germination viability and the total germination at
20oC and 25oC, respectively. The hybrid Altesse RM had the best germination
viability and the total germination at 25oC, while the remaining two hybrids had the
correspond...ing values at alternating temperatures of 20-30oC. The gained results point
out that studied sunflower hybrids had different temperatures of germination viability
and total germination.
