Abstract
Vrtnice so ene od najstarejših znanih okrasnih rastlin in so še vedno najbolj priljubljene. V antiki so jih gojili zaradi prijetnega vonja, lepega videza in pridobivanja eteričnih olj. Danes ločimo med 140 in 180 botaničnih vrst vrtnic, med katerimi so bili požlahtnjeni številni križanci in sorte. Zaradi velike številčnosti in pestrosti vrtnice delimo na različne načine, glede na tip cveta, pogostost cvetenja, obliko šipkov itd. Ena od delitev v skupine je tudi glede na obliko rasti, kjer so poznane te skupine vrtnic: rožni grmi, velecvetne, mnogocvetne, atrijske vrtnice, poliante, pritlikave vrtnice, prekrovne, plezavke in popenjave vrtnice. V diplomski nalogi smo pregledali literaturo, ki opredeljuje dejavnike vpliva na rast in razvoj odraslih vrtnic. Dejavniki, kot so temperatura, svetloba, izbira primerne lege in rastišča, vplivajo na le na rast in razvoj, pač pa tudi na kakovost vrtnic. Če so dejavniki optimalni, bodo vrtnice dlje in bolj intenzivno cvetele. Jakost svetlobe je najpomembnejši dejavnik, ki vpliva na rast in cvetenje vrtnic. Do sprememb v cvetenju, kakovosti, tvorbi poganjkov in obarvanju venčnih listov pride, če se zmanjša intenzivnost svetlobe in trajanje osvetlitve zaradi sezonskih sprememb. Zaradi zelo nizkih in visokih temperatur, ki sta ozko povezane z vlago in vetrom, moramo poznati različne sorte vrtnic, saj niso vse odporne. Vrtnice iz vsake skupine sadimo na različno sadilno razdaljo, ker je velikost v odrasli dobi drugačna. Pravilna oskrba tal z mikro- in makro-hranili ter pravočasna in pravilna rez nam omogočajo, da so vrtnice lepo rastoče in zdrave.

Title:Description of different groups of roses (Rosa spp.) and factors influencing their growth and development
Abstract:
Roses are one of the oldest known ornamental plants and are still the most popular. They were cultivated in ancient times for their pleasant smell, beauty, and essential oils. Today we differentiate among 140 and 180 botanical rose species, numerous hybrids, and cultivars. Due to a large number and variation of roses, the plants can be classified according to the type of flower, the frequency of flowering, the shape of the flowers, etc. Some of the best-known groups of roses are rose bushes, large-flowered, multi-flowered, atrium roses, polyanthus roses, dwarf roses, covering, rambling, and climbing roses. In the thesis, we will present the factors influencing the growth and development of roses. Factors such as temperature, light, s location and site affect the growth, development and quality of roses. If the factors are optimal, the roses will bloom for a longer period and more intensely. Light intensity is the most important factor affecting the growth and flowering of roses. Changes in flowering, quality, shoot formation and petal coloration occur when light intensity and duration of the light period are reduced due to seasonal changes. Due to very low and high temperatures, which are closely related to humidity and wind, knowledge on different rose varieties is important, as not all are resistant. Roses from each group are planted at different planting distances, because the size of mature plants differs. Proper supply of soil with micro- and macro-nutrients, and timely and correct pruning affect the growth and health of roses.

Keywords:rose, groups of roses, growth, development, light, temperature
