Abstract

U radu je provedena morfometrijska analiza epidermskih stanica latica različitih
kultivara maćuhice (Viola x wittrockiana Gams.) te su opisane razlike s obzirom na vizualne
karakteristike latica. Kod svih istraživanih kultivara maćuhice, stanice adaksijalne epiderme
bile su čunjastog oblika. Međutim, visina stanica, kut koji zatvaraju vanjske stijenke i
polumjer vrha stanica su u različitih kultivara znatno varirali. Stanice abaksijalne epiderme
latica bile su lećasto ili blago čunjasto izbočene te znatno niže od stanica adaksijalne
epiderme. Izrazito baršunast izgled latica imali su samo kultivari vrlo tamnih boja cvjetova.
Morfometrijski parametri stanica adaksijalne epiderme među ovim su se kultivarima znatno
razlikovali što upućuje na zaključak da baršunasti izgled latica u većoj mjeri ovisi o visokoj
koncentraciji pigmenata nego o morfometrijskim karakteristikama čunjastih epidermskih
stanica.

Abstract (english)

In this Thesis, a morphometric analysis of the petal epidermal cells of various
cultivars of garden pansy (Viola x wittrockiana Gams.) was conducted, and differences with
respect to the visual characteristics of the petals described. In all examined cultivars, the
adaxial epidermal cells were conical. However, the cell height, the angle between the outer
cell walls, and the cell tip radius varied considerably in different cultivars. The epidermal cells
on the abaxial side of the petals had lens-shaped or slightly conical outer walls and the cell
height was markedly lower than in the adaxial epidermis. Among the examined cultivars, the
petals of only those of very dark flower colours had pronouncedly velvety appearance. The
morphometric parameters of the adaxial epidermal cells in these cultivars differed
considerably, indicating that the velvety appearance is more dependent on high pigment
concentration than on morphometric characteristics of the conical cells.
