Researches on the Advantages for the Environment of Using Bio-Fuels to Vehicles

2011

The paper presents researches on the possibilities and advantages for the environment of using bio-fuels , especially bio-ethanol and bio-gas. The international context is favorable to using bio-fuels, considering that a direction of European Union establishes that in 2020, 20% of the energy consumption of Romania must be provided by rechargeable energy. One source for producing bio-fuels, not so much used until now is sugar beet. Sugar beet wastes are estimated as 1.22 times sugar production, since the total dry matter of processing wastes and field wastes exceed the weight of sugar in the ratio of 55:45. The novelty of the present paper approach is the fact that sugar beet is less used fo…

Differentiation of the Disease Caused by Aphanomyces cochlioides and Girth Scab on Sugar Beet Roots – a Review

2017

Severe symptoms of root rot on sugar beet have been observed in Poland and Germany since 2001. The symptom classification suggested girth scab as it was mistakenly classified on the basis of current classification, e.g. in LIZ. However, the cause of the disease was Aphanomyces cochlioides infection, not Streptomyces spp. According to these findings we cannot call the symptoms caused by A. cochlioides as ‘girth scab’. The typical scab (girth scab) symptoms can be promoted by A. cochlioides infections. In many cases, A. cochlioides developed at the beginning of the season, during the seedling stage. Its further development was due to rainfall and was not routinely recognised in disease-change…

Association with the Syndrome "Basses Richesses" of Sugar Beet of a Phytoplasma and a Bacterium-Like Organism Transmitted by a Pentastiridius sp.

2002

The syndrome “basses richesses” of sugar beet (SBR) was first observed in 1991 in Burgundy, France. A cixiid planthopper, Pentastiridius beieri, has been proved to be involved in the transmission to sugar beet of a stolbur phytoplasma, which could be detected in some affected plants. In 2000, periwinkle and sugar beet exposed to field-collected cixiids developed symptoms similar to SBR on sugar beet. Use of 4′-6-diamidino-2-phenylindole (DAPI) staining and transmission electron microscopy confirmed the presence of phytoplasma in some of the plants, which were also positive for this pathogen in a polymerase chain reaction (PCR) analysis. A phloem-restricted gram-negative bacteria was seen i…

Burakochwasty i pośpiechy na plantacjach buraka cukrowego

2018

Burak cukrowy stanowi jedną z ważniejszych upraw rolniczych w Polsce. Zjawisko pośpiechowatości na skutek wernalizacji roślin było wcześniej znane, jednak rośliny te w znakomitej większości nie wytwarzały nasion. Od lat 90. ubiegłego stulecia, wraz z wprowadzeniem nasion reprodukowanych w basenie Morza Śródziemnego, w uprawie tej pojawiły się rośliny wytwarzające nasiona w pierwszym roku wegetacji. Są one efektem przekrzyżowań materiałów hodowlanych z gatunkami dzikimi buraka tam występującymi. Zaniedbania ze strony plantatorów doprowadziły do wzrostu ich liczebności i znacznego zachwaszczenia nimi pól buraka. Monitoring plantacji w rejonach zachodniopółnocnych kraju wykazał, że na wielu po…
