Effect of row orientation and elevation on leaf morphology of grapevine (Vitis vinifera L.) c.v. Furmint

Abstract

Grapevine (Vitis vinifera L.) shows morphological plasticity influenced by environmental factors such as radiation and temperature. The effect of row orientation, exposition of leaves and orchard altitude on leaf morphological traits was evaluated. Grapevine cultivar ‘Furmint’ was investigated in this study with the new version of the GRA.LE.D. raster graphic software. The standard OIV (International Organization of Vine and Wine) descriptors were used with additional size parameters. High morphological variability was observed among the leaves collected from 4 different row orientations and 5 levels of expositions. Exposition levels were assigned according to the estimated total radiation collected by leaves at their position. Selected parameters also responded sensitively to changing elevation in the range of 110–289 m. According to the results, traditional leaf morphological investigations performed with machine vision systems may be recommended to reveal significant ecological factors on ampelometric traits.

Genetic diversity of grapevine (Vitis vinifera L.) cultivars in Al-Madinah Al-Munawara based on molecular markers and morphological traits

“…This finding was also reported by Santiago et al (2007); Ates et al (2011), where they found that the mature leaf was very informative in discriminating grapevine genotypes, and also it was more stable and objective than other characters. Also, according to Bodor et al, (2014), description of the leaf has a great importance since it is different from the other morphological characters where the characterization is not limited by a certain time through the year.…”

“…that are recognized by the intergovernmental organization OIV (2009). Moreover, these characterizations are useful to provide a base of comparison between the cultivars (Bodor et al, 2014).…”

Landmark-based morphometry reveals phyllometric diversity along the shoot axis of the grapevine (Vitis vinifera L.)

“…Thirty-two biometric landmarks were recorded with the GRA.LE.D. 2.04. raster graphic software according to Bodor et al (2012Bodor et al ( , 2014. Semiautomatic software records the Cartesian coordinates of each landmarks on a sample.…”

“…Fifty-four leaf morphological characteristics (Bodor et al, 2014) were evaluated: length of the veins, angles between the veins, depth of sinuses, distance between lobe tips, size of the serrations in the top of the lobes. ANOVA analysis was carried out to explore difference among the leaf layers from the 1 st to the 25 th nodes.…”

Effect of environmental gradients on leaf morphological traits in the Fandoghlo forest region (NW Iran)

“…Temperature decreases, while precipitation and radiation increase with increasing altitude (Li et al 2018). The orientation of tree crown according to the cardinal points can also have a complex impact on climatic parameters by modifying temperature and light conditions, which also influence leaf morphology and physiology (Bodor et al 2014). For example, south exposed leaves are subject to higher light radiation and harsher drought conditions than leaves exposed northwards.…”
