Influence of variety and weather conditions on fatty acid composition of winter and spring Camelina sativa varieties in Poland

Abstract

The aim of this study was to determine the influence of weather conditions over the course of 4 years (2016–2019) on the fatty acid profile of Camelina sativa. It was assumed that varieties and functional forms of plants (spring and winter genotypes) were characterized by a different fatty acid composition and that weather conditions affected the profile of fatty acids in camelina seeds. Statistical analyses were performed based on the results of chemical tests. Differences were found in the mean concentrations of C18:3n3, C18:3n6, C20:2 and C22:1 acids in all genotypes based on the Kruskal test. Two winter genotypes (Maczuga and 15/2/3) and the spring genotype UP2017/02 had the significantly highest content of C18:3n6. Genotypes CSS-CAM31, CSS-CAM30, BRSCHW 28347, CSS-CAM36 and Kirgzkij showed the highest content of C18:3n3. The lowest C18:3n3 content was found in winter genotypes: K9/1, 15/2/3, Przybrodzka (winter form) and C5. It was found that weather conditions deviating from the long-term average, both in terms of temperature and precipitation, did not affect the quantitative profile of fatty acids. Over the 4 years, no differences were observed in the fatty acid profile between the spring and winter forms. Observations made in this study allow to state that spring and winter forms of Camelina sativa retain a constant fatty acid composition regardless of changing weather conditions.

Winter camelina seed quality in different growing environments across Northern America and Europe

“…The significant variation in all the main FAs of Joelle oil reported in the present study differ from the results of Kurasiak-Popowska et al (2020a), which highlighted the high compositional stability of different winter and spring camelina lines grown in the same environment in Poland over three consecutive growing seasons.…”

Correlational Analysis of Agronomic and Seed Quality Traits in Camelina sativa Doubled Haploid Lines under Rain-Fed Condition

“…Our studied 136 DH lines derived from 15 different crosses helped us to find out the relationships between the seed yield and oil quality as a key factor to achieve high yielding cultivars with a favorable oil quality under rain-fed conditions. It is also noteworthy to mention the effect of maturation habitat as well as climatic conditions that may significantly affect the oil quality in oilseed crops [54,55]. Among our results there were robust correlations between SY and OC, and SY and DM (Figure 3).…”

CRISPR/Cas9-Induced fad2 and rod1 Mutations Stacked With fae1 Confer High Oleic Acid Seed Oil in Pennycress (Thlaspi arvense L.)

“…It remains to be seen how plastic pennycress seed FA composition is under variable farm field conditions. Reports with other species in this regard have been mixed, with camelina varieties showing no variation in seed oil FA composition based on different weather conditions (Kurasiak-Popowska et al, 2021), whereas oilseed rape was found to have higher and lower seed oil linolenic acid content corresponding with warmer and cooler weather conditions, respectively (Wójtowicz and Wójtowicz, 2020).…”
