Abstract
Cilj rada bio je utvrditi morfološke i fiziološke odgovore presadnica vodenike (Impatiens x hybrida SunPatiens 'Compact Orchid Blush') na tri različite varijante (obroka) navodnjavanja: 100 % poljskog vodnog kapaciteta (kontrola), 80 % kontrolne varijante i 60 % kontrolne varijante. Navodnjavanje u manjim obrocima rezultiralo je smanjenjem visine i širine biljaka te veličine listova i cvjetova. Broj otvorenih cvjetova i broj uvelih cvjetova se nisu značajno razlikovali između različitih varijanti navodnjavanja, no broj cvjetnih pupova se značajno smanjio. Navodnjavanje u manjim obrocima nije značajno utjecalo na maksimalni kvantni prinos fotosustava II (Fv/Fm) i sadržaj ukupnih klorofila, no povećalo je omjer klorofila a i b te sadržaj karotenoida. Slabija opskrba biljaka vodom također je rezultirala značajnim smanjenjem veličine stanica zapornica i otvora puči, ali ne i razlikom u broju puči po jedinici lisne površine. Rezultati istraživanja upućuju na zaključak da je deficitarno navodnjavanje moguće koristiti za proizvodnju presadnica vodenike komercijalno zadovoljavajuće kvalitete.
Abstract (english)
The aim of this study was to investigate the morphological and physiological responses of impatiens transplants (Impatiens x hybrida SunPatiens 'Compact Orchid Blush') to three different irrigation rates: 100 % of field water capacity (control), 80 % of the control and 60 % of the control. Lower irrigation rates led to a reduction in the height and width of the plants as well as the size of the leaves and flowers. The number of open flowers and wilted flowers did not differ significantly between the different irrigation treatments, whereas the number of flower buds significantly decreased. Lower irrigation rates had no significant effect on the maximum quantum yield of photosystem II (Fv/Fm) and the content of total chlorophyll. However, the ratio of chlorophyll a and b and the content of carotenoids increased in less irrigated plants. Reducing the water supply to the plants also led to a significant reduction in the size of guard cells and stomatal pores, but had no effect on the number of stomata per unit leaf area. The study suggests that deficit irrigation can be used to produce impatiens of commercially satisfactory quality.
