نویسندگان
چکیده
Bu çalışma, in vitro ve vivo koşullarda farklı kaynaklardan izole edilen bakteri strainlerinin Erwinia amylovora’nın gelişimini engelleme potansiyellerini belirlemek amacıyla yapılmıştır. Patojen olarak Iğdır ilinde hastalık semptomu gösteren elma (Malus domestica L.) ağaçlarından 5 E. amylovora straini kullanılmıştır. In ortamda patojene karşı 130 test edilmiş bunlardan 34’ü etkili bulunmuştur. 34 bakterinin biyokontrol etkisi sürgün inokulasyonu ile edilmiştir. Pseudomonas putida strain BY-6 Pantoea agglomerans MÜ-1 hastalığı % 80 oranında engelleyerek en başarılı strainler olduğu tespit Diğer strainlerin ise 9-60 engelledikleri saptanmıştır. Biyokontrol etkinliği etki mekanizmaları (ACC-deaminaz, HCN siderofor üretimi, proteaz, selülaz kitinaz aktiviteleri) belirlenmiştir. Elde bulgular, bulunan patojenin entegre mücadele programına dahil edilmesiyle kontrolünde olumlu sonuçlar alınabileceği göstermektedir.

Ethylene biosynthesis and perception in apple fruitlet abscission (Malus domestica L. Borck).
Abscission was studied in immature apple fruits (cv. Golden Delicious) during the physiological drop. Fruitlet populations, characterized by different abscission potential, were analysed. Non-abscising fruitlets (NAF) were obtained from central flowers borne in clusters where all the lateral flowers had been removed at bloom while abscising fruitlets (AF) were derived from lateral fruitlets of ...
متن کاملTranscriptomic Signatures in Seeds of Apple (Malus domestica L. Borkh) during Fruitlet Abscission
Abscission is the regulated process of detachment of an organ from a plant. In apple the abscission of fruits occurs during their early development to control the fruit load depending on the nutritional state of the plant. In order to control production and obtain fruits with optimal market qualities, the horticultural procedure of thinning is performed to further reduce the number of fruitlets...

متن کاملMetabolic and gene expression analysis of apple (Malus × domestica) carotenogenesis
Carotenoid accumulation confers distinct colouration to plant tissues, with effects on plant response to light and as well as health benefits for consumers of plant products. The carotenoid pathway is controlled by flux of metabolites, rate-limiting enzyme steps, feed-back inhibition, and the strength of sink organelles, the plastids, in the cell. In apple (Malus × domestica Borkh), fruit carot...
