Sažetak
It was evaluated the damage caused by Bruchus pisorum L (Coleoptera:
Chrysomelidae) on the germination ability of pea farage varieties (Pisum sativum L.).
Result of damage by Bruchus pisorum in seeds with parasitized larva was significant
decrease of the germination by 16.4% percentage points, the length and weight of
primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and
14.1%, the vigor index of primary radicle and plumule by 32.5 and 32.8% as well as
the germination index by 17.4%. The inhibitory effect was on average 17.8%.
Essential significant changes in regard to the studied parameters were found for
damaged seeds with bruchid emergence hole. In these seeds the gewrmination
decrease by 58.3% percentage points, the length and weight of primary radicle by
34.1 and 36.2%, the length and weight of plumule by 31.8 and 34.3%, the vigor index
of primary radicle and plumule by 81.1 and 82.1% as well as the germination index
by 83.1%. The inhibitory effect was on average 58.3%. It was found that the
damaged seeds with parasitoid emergence hole provided better possibility for growth
and development of plants whereas the damaged seeds with bruchid emergence
hole had significantly low germination, vigor and sowing characteristics. These seeds
could not provide the establishment of well-garnished stand and stable yields. As
tolerant to damage by Bruchus pisorum was distinguished Glyans variety for which
the values of parameters related to germination and vigor of seeds were influenced in
the lowest degree from the damage unlike the sensitive Pleven 4 variety. Dominant
factor influencing germination ability of seeds for all analyzed parameters was the
type of seeds compared to varietal appurtenance.
