AB  - Phenotypic measurements under controlled cultivation conditions are essential to gain a mechanistic understanding of plant responses to environmental impacts and thus for knowledge-based improvement of their performance under natural field conditions. Twenty maize inbred lines (ILs) were phenotyped in response to two levels of water and nitrogen supply (control and stress) and combined nitrogen and water deficit. Over a course of 5 weeks (from about 4-leaf stage to the beginning of the reproductive stage), maize phenology and growth were monitored by using a high-throughput phenotyping platform for daily acquisition of images in different spectral ranges. The focus of the present study is on the measurements taken at the time of maximum water stress (for traits that reflect plant physiological properties) and at the end of the experiment (for traits that reflect plant architectural and biomass-related traits). Twenty-five phenotypic traits extracted from the digital image data that support biological interpretation of plant growth were selected for their predictive value for mid-season shoot biomass accumulation. Measured fresh and dry weights after harvest were used to calculate various indices (water-use efficiency, physiological nitrogen-use efficiency, specific plant weight) and to establish correlations with image-derived phenotypic features. Also, score indices based on dry weight were used to identify contrasting ILs in terms of productivity and tolerance to stress, and their means for image-derived and manually measured traits were compared. Color-related traits appear to be indicative of plant performance and photosystem II operating efficiency might be an importance physiological parameter of biomass accumulation, particularly under severe stress conditions. Also, genotypes showing greater leaf area may be better adapted to abiotic stress conditions.

AB  - Snabdevanje biljaka vodom i dostupnost azota su glavni faktori koji utiču na produktivnost kukuruza širom sveta. U ovom eksperimentu proučavan je razvoj nadzemnog dela biljake 20 inbred linija kukuruza u uslovima nedostatka vode i azota tokom vegetativnog razvoja (počev od faze šestog lista pa do početka metliĉenja) uz pomoć automatskog merenja biljaka. Blizu 200 digitalnih osobina je dobijeno obradom fotografija nastalih uz pomoć vidljive, fluorescentne i blisko-infracrvene svetlosti. Odabrano je 25 reprezentativnih digitalnih osobina za dalje analize. Takođe, poslednjeg dana eksperimenta na klasičan naĉin su merene sveža i suva masa nadzemnog dela biljke, relativni sadržaj vode u listu, sadržaj hlorofila u listu i broj listova po biljci.
AB  - Water supply and nitrogen availability are major abiotic factors affecting agricultural productivity of maize worldwide. In this experiment we have evaluated shoot developmental characteristics of twenty maize inbred lines, under water and nitrogen shortage in mid to late vegetative stage (from-leaf six up to start of tasseling) using high-throughput automated phenotyping platform. Nearly 200 digital traits have been extracted from automated imaging by visible (color), fluorescence and near-infra-red imaging systems. In addition, fresh and dry weight, relative water content, chlorophyll content and leaf number were measured manually at the end of the experiment. A set of 25 representative digital traits has been chosen for further analysis. Limited water supply was the main restrictive factor in maize shoot development for all the genotypes (detectable ten days after the beginning of the stress), while the effect of limited nitrogen supply mostly could not be observed until the very end of the experiment.
