| Abstract: | The microscopic analysis of leaflet, petiole, stem and peduncle of 26 populations of 17 Trifolium species was carried out in order to examine their structural characteristics related to digestibility, to compare them between
the populations of forage species and their wild relatives and to evaluate, from histological aspect, the potential of wild-growing
species to be used as forages. Forage species had low proportion of the tissues composed of thick-walled cells and high proportion
of the tissues composed of thin-walled cells in all examined plant parts. The reduction of the proportion of lignified xylem,
sclerenchyma and sclerenchymatous interfascicular parenchyma, were suggested as basic selection criteria in breeding Trifolium species for improved digestibility. T. angulatum, T. medium and T. pannonicum proved to be very similar to the forage species in their histological composition, proportion of thick-walled and thin-walled
cells and type of variation of the examined parameters. We believe that these species have some potential for use as forages
in their own right, but aditional biochemical, physiological and morphological investigations should be conducted. |
