Nitrogen assimilation and photosynthetic capacity of wheat genotypes under optimal and deficient nitrogen supply.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The performance of two contrasting Bulgarian wheat varieties (Slomer, an old tall cultivar, and Enola, a modern semi-dwarf one) to nitrogen deficiency was compared by measuring biochemical parameters characterizing N uptake and assimilation as well as growth and photosynthetic activity of young seedlings. The old genotype displayed better photosynthetic capacity, higher N assimilation expressed by elevated amino acid synthesis and better overall performance under N limitation. This could be explained by the fact that selection of old varieties was performed mostly in environments with low nutrient availability and consequently these genotypes proved to be more suitable for growing on low-input conditions. Upon limiting N supply modern variety preferentially accumulated sugars while the old one retained higher amino acids levels. It was demonstrated that processes involved in N metabolism were tightly interrelated with photochemical reactions and carbon assimilation even at early developmental stage.
