Objective: To phenotypically and molecularly characterize identify the causal agent of onion (Allium cepaL.) bulb rot in Morelos, Mexico.Methodology: Fluorescent bacteria from tissue with symptoms were isolated; LOPATtest was used to describe them subsequently they identified by partial 16S rRNA gene amplification.Pathogenicity vegetables plants evaluated injecting a suspension 108 CFU mL-1of p...

Tohum kalitesi ve gücü (vigor) sebze üretiminde verim kaliteyi etkileyen en önemli faktördür. Çabuk bozulma özelliği gösteren pırasa tohumlarının (Allium porrum L. cv. İnegöl) çıkış gücünü iyileştirmek için tohumlar -1.0 MPa osmotik potansiyele sahip PEG6000 and KNO3 çözeltilerinde (osmopriming) suda (hidropriming) farklı sürelerde (6, 12 24 saat) tutulmuştur. Daha sonra oda koşulları sabit 30°...

The interphase nucleolus in Allium porrum, as in many of the plant species studied so far, is highly heterogeneous in ultrastructure owing to the presence of coarse, contorted, thread-like structures, or nucleolonemata. Each nucleolonema appears to be sharply twisted and to give rise to a skein within the nucleolar mass. In order to characterize further these nucleolar components, a variety of ...
