Morphological Characteristics of Grapevine Cultivars and Closed Contour Analysis with Elliptic Fourier Descriptors.

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
Morphology is the most visible and distinct character of plant organs and is accepted as one of the most important tools for plant biologists, plant breeders and growers. A number of methods based on plant morphology are applied to discriminate in particular close cultivars. In this study, image processing analysis was used on 20 grape cultivars ("Amasya beyazı", "Antep karası", "Bahçeli karası", "Çavuş", "Cevşen", "Crimson", "Dimrit", "Erenköy beyazı", "Hafızali", "Karaşabi", "Kırmızı", "İzabella (Isabella) ", "Morşabi", "Müşgüle", "Nuniya", "Royal", "Sultani çekirdeksiz (Sultanina)", "Yalova incisi", "Yerli beyazv", "Yuvarlak çekirdeksiz") to classify them. According to image processing analysis, the longest and the greatest projected area values were observed in "Antep karası" cultivar. The "Sultani çekirdeksiz" cultivar had the least geometric mean diameter. The greatest sphericity ratios were observed in "Yerli beyaz", "Erenköy beyazı" and "Amasya beyazı" cultivars. According to principal component analysis, dimensional attributes were identified as the most significant source of variation discriminant grape cultivars from each other. Morphological differences between the cultivars were explained by sphericity and elongation variables. According to elliptic Fourier analysis (EFA) results, grape morphology largely looks like ellipse and sphere. However, there are some cultivars that look similar to a water drop. The cultivars with similar morphology were identified by a pair-wise comparison test conducted with the use of linear discriminant analysis, and they were presented in a scatter plot. According to cluster analysis, present grape cultivars were classified into seven sub-groups, which indicated great diversity.
