Allelopathic effects of aqueous extracts of Sorghum halepense L. (Pers.) on seed
germination and primary seedling growth and development of two lupine species
was studied. Lupinus albus and Lupinus luteus showed different levels of susceptibility
to the allelopathic effect of weed extracts. Increasing concentrations (1.25, 2.50, 5.00
and 10.00%) of extracts from aboveground and belowground biomass suppressed
seed germination of L. luteus from 53.2 to 74.7%. The germination of L. albus seeds was
unaffected, except by the highest concentration of 10.00%. Fresh biomass accumulation in
the initial germ of L. luteus was inhibited by 3.8-40.3% under the effect of concentrations
of 2.50, 5.00 and 10.00%, which made the species susceptible to S. halepense extracts. L.
albus was tolerant as it was not found to sustain a significant allelopathic effect of the
extracts. Proučavan je alelopatski uticaj vodenih rastvora Sorghum halepense L. (Pers.) na klijanje
semena i primarni rast i razvoj dve vrste lupina. Vrste Lupinus albus i Lupinus luteus su pokazale
različitu osetljivost na alelopatski uticaj rastvora ispitivanog korova. Rastuće koncentracije
(1.25, 2.50, 5.00 i 10.00%) ekstrakata nadzemne i podzemne biomase korova inhibirale
su klijanje semena L. luteus od 53.2 do 74.7%. Nije bilo uticaja na klijanje semena L. albus,
osim kod najviše koncentracije od 10.00%. Akumulacija biomase klice L. luteus inhibirana je
3.8-40.3% pod uticajem koncentracija od 2.50, 5.00 i 10.00%, što ovu vrstu čini osetljivom na
ekstrakt S. halepense. L. albus se pokazala kao otporna vrsta jer na nju ispitivani ekstrakti nisu
pokazali značajan alelopatski uticaj.
