Opis:: The present study investigated the effect of different soil moisture content levels (60 – 70% SWC (soil water capacity) – control; 30 – 35% SWC – water stress) on yields, gas exchange parameters, seed health, and protein fractions of husked oat grain. The study showed that water deficit resulted in a decrease in grain weight per plant and a reduction in the gas exchange rates, primarily the photosynthesis and transpiration rates. Cladosporium cladosporioides was the dominant species on oat kernels in both experimental treatment options and in both years of the study. The presence of Fusarium poae was also found. Higher contents of prolamin, albumin and globulin fractions were found in the oat grain harvested from plants grown under soil water deficit conditions.

Opis:: Seeds of the Andean lupine are characterised by high nutritional value, and the plant could become an important crop in the production of food and forage. This legume continues to attract growing interest around the world. A field experiment was carried out in in Lower Silesia, Poland, in 2011-2012. Two Andean lupine morphotypes (indeterminate and determinate) were analysed. Andean lupine was grown in treatments characterised by different sowing dates and plant density per m2. Seed yield, macronutrient content, protein content and health were evaluated at harvest. Seed yield was determined by the interaction of all experimental factors. The indeterminate form produced a significantly higher yield than the determinate form, regardless of the sowing date. The factors had little influence on the mineral content of seeds and total protein content. Andean lupine seeds were colonised mostly by saprotrophic fungi of the genera Alternaria, Cladosporium, Epicoccum and Rhizopus and pathogenic fungi of the genera Botrytis, Colletotrichum and Fusarium. Delayed sowing contributed to seed colonisation by fungi of the genus Colletotrichum. The determinate form was more susceptible to infection than the indeterminate form. Molecular analysis showed that the Colletotrichum isolates found in the study belong to the Colletotrichum acutatum species complex. The pathogen causing lupine anthracnose, isolated from the seeds of Andean lupine in the present study, was identified as Colletotrichum lupini (within C. acutatum complex) in a molecular analysis, and its DNA sequence was compared with those of the isolates deposited in the GenBank.

Tytuł:: The effect of water stress on the gas exchange parameters, productivity and seed health of buckwheat (Fagopyrum esculentum Moench)

Opis:: The present pot experiment studied the effect of different soil moisture contents (60 – 70% CWC (capillary water capacity) – control; 30 – 35% CWC – water stress) on buckwheat productivity, the gas exchange parameters and health of buckwheat nuts. It was found that water deficit affected adversely certain biometric features investigated (plant height, number of nuts per cluster) and caused a decrease in seed weight per plant. It was also shown that water stress reduced the values of the investigated gas exchange parameters (photosynthesis rate, transpiration rate, intercellular-space CO2 concentration, and stomatal conductance) relative to the control treatment. Different soil moisture contents did not have a clear effect on fungal colonization of seeds. The multiplex PCR assays did not enable the detection of the genes responsible for mycotoxin synthesis. Under water deficit conditions, an increase was found in the content of albumin and globulin fractions as well as of glutelin fractions.

Opis:: W latach 2004-2005 mierzono intensywność fotosyntezy, transpiracji, międzykomórkowe stężenie CO2 oraz przewodność szparkową dwóch odmian pszenicy ozimej. Ponadto określono zasiedlenie grzybami ich ziarniaków. Wykazano, że deficyt wody spowodował obniżenie wskaźników wymiany gazowej, cech biometrycznych i masy ziarna. Stwierdzono niższe zasiedlenie ziarna obu odmian pszenicy przez patogeny grzybowe na obiektach z niedoborem wody w pierwszym roku badań. W kolejnym roku zależności nie były jednoznaczne.
The rate of photosynthesis and transpiration, intercellular CO2 concentration, and stomatal conductance of two cultivars of winter wheat were determined in the study. The severity of fungal infection of the grain was also estimated. It was found that water deficit decreased the values of gas exchange parameters, biometric characters and grain weight. In the first year the number of fungal isolates in wheat grain of both cultivars was lower under water stress conditions. However, in the next year the findings were ambiguous.
