Morphological and agronomic characteristics of winter rye cultivars in connection with their resistance to lodging

Background. Lodging resistance of winter rye is associated with morphological features of the stem. Searching for source material to breed non-lodging high-yielding cultivars requires studying the varietal phenotypic diversity according to morphological characters of the stem that affect the resistance to lodging and the productivity of the ear.Materials and methods. Experiments were carried out in 2017–2020 at the Federal Agricultural Research Center of the North-East (FARC North-East), Kirov. Field resistance to lodging, morphological characteristics of the stem, yield, and ear productivity were evaluated in 16 winter rye cultivars. The study was based on the International COMECON List of Descriptors for the Genus Secale L., and Methodology for the State Variety Trials of Agricultural Crops. The weight of segments of the second lower internodes was measured in 10 plants of each cultivar under laboratory conditions.Results and conclusions. Negative correlations of lodging resistance with stem length (r= –0.55) and the weight of the second lower internode (r = –0.65) were revealed. Ear productivity of rye cultivars was significantly associated with the wall thickness (r = 0.52) and the length of the second lower internode (r = –0.52). According to the results of the path analysis, the main causes of a decrease in lodging resistance were the weight of the segment (P = –0.467) and the length of the second lower internode (P = –0.408), while an increase was connected with the wall thickness of the second lower internode (P = 0.424). The cultivars differed significantly in their resistance to lodging (LSD05 = 0.8). Cvs. ‘Moskovskaya 12’, ‘Tatyana’, ‘Bylina’ and ‘Yantarnaya’ were identified; they are recommended as source material for breeding for lodging resistance

Применение левосимендана при трансплантации легких в условиях ВА ЭКМО

Chronic heart failure is one of the most dreadful complications in the early postoperative period following lung transplantation. At the same time, the effect of using levosimendan in the early post-lung transplant period is currently insignificant and remains debatable. This paper presents a clinical case where levosimendan was successfully used in a patient with right ventricular heart failure during lung transplantation undergoing central venoarterial extracorporeal membrane oxygenation (VA-ECMO).Одним из наиболее грозных осложнений в раннем послеоперационном периоде после трансплантации легких является развитие сердечно-сосудистой недостаточности. В то же время опыт применения левосимендана в раннем периоде после трансплантации легких в настоящее время незначителен и остается дискуссионным. Представлен клинический случай успешного применения левосимендана у пациента с правожелудочковой сердечной недостаточностью при трансплантации легких в условиях использования центральной вено-артериальной экстракорпоральной мембранной оксигенации (ВА ЭКМО)

Winter hardiness in winter rye: problems and solutions

High winter hardiness is an advantage of winter rye over other cereals. This trait is determined by a number of parameters: biological and genetic properties, weather conditions and technological features. The main reasons of failure of winter rye sowings in North-East of European Russia are frost-killing and asphyxiation. Frost-killing is characteristic for beginning of winter with low snow cover and for cold spell in spring. The critical situation with frost damage in the region was recorded in 2009-2010 when soil temperature at the depth of tillering zone site continuously kept at -18 °С day and night. The depth of soil freezing was more than a meter. Winter wheat and triticale were almost completely winterkilled in Kirov region. The failure rate of winter rye Falenskaya 4 in Federal Agricultural Scientific Center of North-East was equal to 17%. Annual damage of rye production in the region is caused by asphyxiation and affection by snow mold (M nivale). On the average damage caused by this disease is 15-20% and in some years even more. Other unfavorable factors of overwintering are shell ice, damping-off and pushing-out of crops. Stability of winter rye production depends on observing the cultivation technology and breeding of highly winter-hardy varieties. Thus, winter resistance is one of the key priorities of breeding programs in North-East of European Russia. The development of such varieties depends on improvement the breeding methods and use of sources of winter hardiness corresponded to region conditions
