Abstract
U radu su analizirani morfološki i fiziološki odgovori presadnica madagaskarskog zimzelena (Catharanthus roseus (L.) G.Don 'SunStorm Red') na tri različite varijante (obroka) navodnjavanja: 100%, 80% i 60% PVK (poljski vodni kapacitet). Smanjeno navodnjavanje dovelo je smanjenja duljine i promjera stabljike, širine biljaka, broja bočnih grana s vidljivim cvjetnim pupovima i veličine listova, no nije značajno utjecalo na broj nodija do prvog cvijeta i debljinu listova. Indeks sadržaja klorofila (CCI) je kod obje varijante smanjenog navodnjavanja bio povećan. Veličina puči je u biljaka slabije opskrbljenih vodom na obje strane lista bila smanjena, a broj puči po mm2 se na abaksijalnoj strani lista povećao. Slabija opskrba vodom nije u većoj mjeri utjecala na vrijeme početka cvatnje, no smanjila je promjer cvijeta, a kod 60% PVK varijante navodnjavanja, i broj cvjetnih pupova. Provedena istraživanja pokazala su da istraživani kultivar madagaskarskog zimzelena dobro tolerira primijenjene razine smanjenog navodnjavanja. Iako je smanjena opskrba vodom utjecala na morfološke parametre biljaka, ove promjene kod 80% PVK varijante navodnjavanja nisu znatnije narušile vizualne karakteristike presadnica.
Abstract (english)
In this work, morphological and physiological responses of transplants of Madagascar periwinkle (Catharanthus roseus (L.) G.Don 'SunStorm Red') to three different irrigation levels (variants), 100%, 80% and 60% FWC (field water capacity), were analyzed. Deficit irrigation led to a decrease in stem length and diameter, plant width, number of lateral branches with visible flower buds and the size of the leaf blade, but did not affect the number of nodes formed before flowering and leaf thickness. Chlorophyll content index (CCI) was increased in both variants of reduced irrigation. In plants under deficit irrigation, the size of the stomata on both sides of the leaves decreased, while stomatal density on the abaxial side of the leaves increased. Deficit irrigation did not affect the start of flowering, but it reduced flower diameter and, in the 60% FWC variant of irrigation, the number of flower buds. The study showed that the investigated cultivar of Madagascar periwinkle tolerates the applied levels of deficit irrigation well. Although deficit irrigation affected the morphological parameters of the plants, these changes in the 80% PVK irrigation variant did not significantly impair visual quality of the transplants.
