Abstract

Natural regeneration maintenance of cork oak remains a major concern of forest in Algeria. Faced with the deterioration of the health status of the Algerian forests, it is urgent to think otherwise. Acorn is affected by this degradation, showing a low yield and vulnerability to carpophagous attack that disrupt the regularity and abundance of acorns. In this study, metabolites (carbohydrates and lipids) on the different categories of acorns (healthy and attacked) were measured. This assay is completed by a chemical analysis of different extracts acorns by gas chromatography / mass spectrometry. The result indicates that the infestation key content metabolites acorns more at the almond at the level of the pericarp. Chemical analysis of different extracts acorns by gas chromatography / mass spectrometry identify 18 major compounds belonging to different chemical classes (aldehyds, alcohols, ketones, acids, saturated or unsaturated hydrocarbons , terpen , sesquiterpen , etc .... ) . Nonvolatile heavy fraction includes many sesquiterpen and saturated hydrocarbons (C22 to C29) and C28 and C29 polyphenols.

Influence de l’attaque des Carpophages sur les métabolites des glands du chêne-liège (Quercus suber)

 


La manutention de la régénération naturelle des subéraies reste une préoccupation majeure des forestiers en Algérie. Face à la dégradation de l’état sanitaire des forêts algériennes, il est urgent de la penser autrement. La glandée est affectée par cette dégradation, démontrant un faible rendement et une vulnérabilité marquée, face aux attaques d’insectes Carpophages, qui perturbent la régularité et l’abondance de la glandée. Pour cette étude on a dosé des métabolites (glucides et lipides) sur les différentes catégories des glands (sains et attaqués). Ce dosage est complété par une analyse chimique des différents extraits des glands par chromatographie en phase gazeuse / spectrométrie de masse. Le résultat obtenu indique que l’infestation touche le contenu en métabolites des glands plus au niveau de l’amande qu’au niveau du péricarpe. L’analyse chimique des différents extraits des glands par chromatographie en phase gazeuse / spectrométrie de masse a permis d’identifier 18 de composés majeurs appartenant à différentes classes chimiques (aldéhydes, alcools, cétones, acides, hydrocarbures saturés ou insaturés, terpènes, sesquiterpènes, etc.…). La fraction lourde, non volatile, comprend de nombreux sesquiterpènes et hydrocarbures saturés (C22 à C29) et des polyphénols en C28 et C29.

Abstract

Mantar meşesinin doğal gençleştirme işlemleri, Cezayir’deki ormanlar açısından önemli bir mesele olmaya devam etmektedir. Cezayir ormanlarının sağlık durumunun bozulması nedeniyle, ivedilikle tedbir alınması gerekmektedir. Palamut, bu bozulmadan etkilenerek düşük verime sahip olmakta ve palamutların düzenliliği ve bolluğunu bozan karpofaj saldırısına karşı savunmasız kalmaktadır. Bu çalışmada, metabolitlerlerin (karbonhidrat ve lipitler) farklı kategorideki (sağlıklı ve saldırıya uğramış) palamutlar üzerine etkisi ölçüldü. Bu deney, farklı palamut özütleri gaz kromatografisi/kitle spektrometrisi ile kimyasal analize tabi tutularak tamamlanmıştır. Analiz sonucu, Sonuç olarak istila önemli içerik metabolitleri perikarp seviyesinde badem daha meşe palamudu olduğunu gösterir. Gaz kromatografisi/kitle spektrometrisi ile farklı palamut özütlerine uygulanan kimyasal analiz sonucunda, farklı kimyasal sınıflara ait (aldehitler, alkoller, ketonlar, asitler, doymuş veya doymamış hidrokarbonlar, terpen, seskiterpen vs.) 18 temel bileşik tespit edilmiştir. Uçucu olmayan ağır fraksiyon, çok miktarda seskiterpen, doymuş hidrokarbon (C22 ila C29 arası) ve C28 ile C29 polifenollerini içermektedir.
