Seasonal variations in the leaf surface composition of field grown grapevine plants

Abstract

The leaf surface is the first barrier of grapevine plants towards various environmental stressors causing damage in vineyards. For this reason, identification of leaf surface metabolites in grapevine and their putative role in plant-environment interactions is important for viticulture. In this study, the leaf surface components of 16 grapevine plants (Vitis vinifera) growing in an experimental vineyard were analyzed in two consecutive seasons -the summer and the autumn of 2007. Forty-eight individual metabolites typical of the cuticular plant wax were identified by gas chromatography-mass spectrometry (GC--MS). They belonged to the following groups of compounds: hydrocarbons, sterols, terpenes, free and esterified fatty acids, alcohols, aldehydes and ketones. The metabolic profiles of the summer and the autumn samples were statistically different (P < 0.05), which was mainly attributed to the specific insects present in the two seasons and to the adaptation of the grapevine to lower temperatures.

Establishment and Application of a Metabolomics Workflow for Identification and Profiling of Volatiles from Leaves of Vitis vinifera by HS‐SPME‐GC‐MS

“…From the group of terpenes and terpenoids several have been detected in other studies, for example, E‐geraniol, 4‐ethenyl‐2‐methoxy‐phenol and eugenol by Wirth et al (), β‐limonene, β‐ionone and methyl salicylate by Tasin et al (), and β‐myrcene, β‐cyclocitral, E‐citral and allo‐ocimene by Rocha et al (). Batovska et al () also found nonadecane, hexahydrofarnesylacetone, phytol, dihydroactinoline, (2E)‐undecenal, nonanal and decanal in grapevine leaves. From the substance class of alcohols 2‐ethyl‐1‐hexanol, 1‐octanol and 1‐nonanol are reported, for example, by Canuti et al (), and benzenemethanol and benzeneethanol by Wirth et al ().…”

“…Most substances were identified by comparison of mass spectra and RI of authentic standards. Batovska et al () analysed liquid extracts of grapevine leaves and detected more than 125 metabolites.…”

Pengaruh Aplikasi Kompos Gulma Siam Chromolaena odorata terhadap Produksi Senyawa Metabolit Sekunder sebagai Ketahanan Tanaman pada Tanaman Cabai

“…Lebih lanjut, ekstrak daun cabai dari perlakuan kompos gulma siam, NPK, kotoran sapi dan kontrol juga mengandung senyawa dari golongan ester yaitu metil hexanoate dan metil octadec-9-enoate. Pada penelitian Batovska et al, (2009), metil hexadecanoat dan metil octadec-9-enoate memiliki peranan penting dalam komunikasi kimia antara tanaman dengan spesies serangga tertentu.…”

Properties, variations, roles, and potential applications of epicuticular wax: a review

“…The presence of alkyl alkanoates, terpenes, sterols, alkanals, alkanoic acids, ketones, hydrocarbons, and alkanols has been reported in leaves of Actinidia deliciosa (Celano et al, 2006). Batovska et al (2009) studied the leaf wax component of 16 grapevine plants (Vitis vinifera) in summer and autumn. The wax components present in leaves were aldehydes, hydrocarbons, terpenes, free and esterified fatty acids, alcohols, sterols, and ketones.…”
