Abstract

Leta 2019 smo opravili poskus na pelargonijah. Pelargonije veljajo za ene od najstarejših okenskih in balkonskih rastlin pri nas, so zelo priljubljene zaradi bogastva cvetov in nepretrganega cvetenja od rane pomladi do pozne jeseni. Uspevajo na sončnem, polsenčnem in senčnem mestu. V našem poskusu smo se osredotočili, kako osvetljenost stalnega mesta vpliva na rast in razvoj pelargonij, vključno s cvetenjem. Proučevali smo tudi vpliv gnojenja substrata na stalnem mestu na rast in cvetenje rastlin. Spremljali smo višino rastlin, dolžino poganjkov, število poganjkov, dolžino cvetnih stebel, število cvetnih stebel, slanost substrata, temperaturo substrata in količino vode v substratu. Določili smo tudi pH substrata, rastlinam pa smo določili svežo in suho maso. Tekom poskusa smo izmerili tudi sončno svetlobo. Najbolje so uspevale rastline na polsenčni strani. Njihova povprečna višina in število cvetov sta bila večja kot pri rastlinah na sončni strani. Tudi vizualno so bile rastline bujnejše na polsenčni strani. Na sončni strani je direktno sonce poškodovalo liste in cvetove na rastlinah, zato rezultati niso bili najboljši. Rezultati gnojenja rastlin so pokazali najboljše rezultate v balkonskih koritih, gnojenih skladno s priporočili. Najslabše so uspevale rastline na sončnem balkonu in v prekomerno gnojenih balkonskih koritih, če ocenjujemo zgolj rast in razvoj rastlin. Vendar pa so imele rastline v negnojenih koritih manjšo gostoto listov in tudi barva listov je bila slabša. Če bi ocenjevali videz rastlin, so najslabše uspevale rastline na sončnem balkonu v negnojenih balkonskih koritih.

Secondary abstract: In 2019 we did an experiment on pelargoniums. Pelargoniums are one of the oldest plants for balconies and window shelves in Slovenia, and are very popular because of their rich flowers and continuous blooming from early spring to late autumn. They thrive on sunny, semi-sunny and shady places. In our experiment we focused on how much brightness of a permanent place affects the growth and development of the pelargoniums, including blooming. We also studied how the fertilization of the soil on a permanent place affects the growth and blooming of the plants. We monitored plants’ height, shoots’ length, number of shoots, lenght of the plants’ stems, number of plants’ stems, soil’s salinity, soil’s temperature and soil’s moisture. During the experiment we also measured the sunlight. After we finished the experiment, we measured the soil pH, and plants’ fresh and dry mass in the laboratory. Plants on the semi-sunny side thrived best. Their average height and number of flowers were bigger than of the ones on the sunny side. Plants looked lusher in the appearance. The direct sunlight on the sunny side damaged leaves and flowers of the plants so the results weren’t the best. The results of fertilization of plants showed the best results in balcony troughs fertilized according to recommendations. If we combine results in terms of growth, plants grew the worst on the sunny side in over-fertilized troughs. However, plants in the unfertilized troughs had a lower leaf density and the color of leaves was inferior. Visual evaluation analysis showed that plants on the sunny balcony in the unfertilized troughs had the worst growth.
