Enhancement of seed germination in three grass species using chemical and temperature treatments
(Range Management Soc India, Jhansi, 2015)
Seeds of three forage plant species, cocksfoot, tall fescue and perennial ryegrass with good amount of dormancy were chemically treated (25%, 50%, 75% and 98% H2SO4) for different durations and exposed to different ...
Isolation and characterization of Xanthomonas euvesicatoria bacteriophages
(Edizioni Ets, Pisa, 2011)
Host range, plaque morphology, thermal inactivation point, genome size and restriction fragment patterns of ten bacteriophage isolates originating from soil, pepper seed and irrigation water collected from five localities ...
Hosts of stolbur phytoplasmas in maize redness affected fields
(Alma Mater Studiorum, Univ Bologna, Bologna, 2011)
The plant host range of a phytoplasma is strongly dependent on the host range of its insect vector. Maize redness in Serbia is caused by stolbur phytoplasma (subgroup 16SrXII-A) and is transmitted by the cixiid planthoper, ...
The occurrence of 'Candidatus phytoplasma rhamni' in Rhamnus cathartica L. without symptoms
(Alma Mater Studiorum, Univ Bologna, Bologna, 2011)
Common buckthorn, Rhamnus cathartica L., is a small tree or shrub of Eurasian origin that has become invasive in North America. A survey was conducted during 2010 to evaluate occurrence of buckthorn witches' broom (BWB) ...
Identification and genetic characterisation of xanthomonas campestris pv. Campestris as an oilseed rape pathogen in serbia
(Edizioni Ets, Pisa, 2014)
During 2010, black rot symptoms were observed in oilseed rape plants grown in a commercial plot in Serbia. Ten bacterial isolates obtained from diseased plants, and identified as Xanthomonas campestris pv. campestris (Xcc) ...
Stimulative influence of germination and growth of maize seedlings originating from aged seeds by 2,4-D potencies
(Elsevier Sci Ltd, Oxford, 2013)
Background: The 2,4-D (2,4-dichlorophenoxyacetic acid) is using as a growth regulator in tissue culture media. Maize seeds have poor ability to maintain germination rate in the long term. Objective: To examine the possible ...
Temperature effects on common cocklebur (Xanthium strumarium L.) seed germination
(Natl Agricultural Research & Development Inst, Fundulea, 2012)
A better understanding of the seed ecology can be helpful for prediction of the potential of weed species to spread, for prediction of their invasiveness, and for development of more effective weed management strategies. ...
Complete nucleotide sequence and genome organisation of grapevine Bulgarian latent virus
(Springer Wien, Wien, 2011)
The complete genome sequence of grapevine Bulgarian latent virus (GBLV) has been determined. RNA-1 (7,452 nt in length) contains a single ORF of 6,285 nt, encoding a polyprotein with conserved motifs characteristic of the ...
First report of maize redness disease in Hungary
(Alma Mater Studiorum, Univ Bologna, Bologna, 2011)
During 2010, several maize production areas in Hungary were surveyed for the occurrence of maize redness (MR) disease symptoms associated with stolbur phytoplasma, as well as for the presence of the known vector of the ...
A strain of phytoplasma related to 16SrII group in Picris hieracioides L. in Serbia
(Alma Mater Studiorum, Univ Bologna, Bologna, 2011)
During epidemiological survey for phytoplasmas in association with agricultural crops in Serbia, a new species of common weed has been detected to harbor phytoplasmas in Serbia. In 2010, a total of 38 samples of Picris ...
