Abstract

In many forage legumes, hard seed coat is the main problem impeding the
germination by preventing water and gases transport in seed. We evaluated the
effects of mechanical scarification, chilling, different seedbeds (peat and sand) and
their combination on the germination ratio and time of 9 naturally grown legume
species belonging Lathyrus and Vicia genus. Control seeds showed very low
germination ranging from 0% in V. narbonensis and V. sativa to 24% in L. annuus
among to species. Mechanical scarification highly increased germination in all the
species ranging from 27% in V. sativa to 96% in L. sphaericus. The highest
germination of all the investigated species (ranging between 100 and 51%) was
determined in the combination of mechanical scarification and sowing in peat
treatments. Under this treatment, germination was improved greatly from 1% in
control to 100% in V. bythinica while the germination of V. narbonensis increased
from 0% in control to 51%. Any treatment which is highly promotes germination
of one species generally accelerated the germination time of same species. The
effect of treatments subjected to present study on germination ratio and time was
generally, with exceptions higher for Lathyrus species compare to Vicia species.
