Yield and morpnological traits in alfalfa varieties of different origin
(Agricultural Research Communication Centre, Karnal, 2015)
The study was conducted to examine variability of green forage yield (GFY) and morphological traits (tiller length, internodes length, internodes-stem diameter, leaf width and length) in nine alfalfa varieties from USA and ...
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

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. ...
