“…For instance, there is a wide genetic variation among miscanthus genotypes with regard to their heat and cold tolerance [129][130][131]. For some annual industrial crops, such as camelina and safflower, winter-annual genotypes are also available [132][133][134][135]. It would very likely further increase the potential growth suitability of the pre-selected industrial crops to take these genetic variations into account.…”

This study deals with approaches for a social-ecological friendly European bioeconomy based on biomass from industrial crops cultivated on marginal agricultural land. The selected crops to be investigated are: Biomass sorghum, camelina, cardoon, castor, crambe, Ethiopian mustard, giant reed, hemp, lupin, miscanthus, pennycress, poplar, reed canary grass, safflower, Siberian elm, switchgrass, tall wheatgrass, wild sugarcane, and willow. The research question focused on the overall crop growth suitability under low-input management. The study assessed: (i) How the growth suitability of industrial crops can be defined under the given natural constraints of European marginal agricultural lands; and (ii) which agricultural practices are required for marginal agricultural land low-input systems (MALLIS). For the growth-suitability analysis, available thresholds and growth requirements of the selected industrial crops were defined. The marginal agricultural land was categorized according to the agro-ecological zone (AEZ) concept in combination with the marginality constraints, so-called ‘marginal agro-ecological zones’ (M-AEZ). It was found that both large marginal agricultural areas and numerous agricultural practices are available for industrial crop cultivation on European marginal agricultural lands. These results help to further describe the suitability of industrial crops for the development of social-ecologically friendly MALLIS in Europe.

“…The average minimum (Tmin) and maximum (Tmax) temperatures (Figure 1b) measured from 50% flowering to seed maturity (Figure 1c), a particularly important phase for seed quality, were quite variable in the years studied. This particular developmental phase has been reported as the most important in camelina seed development and filling (Walia et al, 2018;Righini et al, 2019). In detail, the average Tmin ranged from 13.5 °C in 2017 to 16.6 °C in 2019, while the average Tmax ranged from 25.6 °C in 2016 to 29.3 °C in 2019.…”

SummarySeeds produce a myriad of Specialized Metabolites (SMs). Nevertheless, despite the essential role of SMs in the interaction of plants with their environment, studying the ability of crop seeds to produce these protective compounds has been neglected. Camelina is an oilseed crop, whose seeds are characterized by high oil content and a unique composition, including broad SM diversity. We characterized SM landscapes in the seeds of six camelina cultivars grown in the open field and harvested during five consecutive growing seasons. We achieved a comprehensive annotation of camelina seed SMs combining molecular and correlation network analyses, which cluster SMs based on their chemical structures and co-accumulation patterns, respectively. Thus, we were able to evaluate the impact of the genotype and environment on the accumulation of these metabolites. Our data showed surprisingly high and unexplored effects of the environment on the stimulation of the seed-specialized metabolome. Moreover, they emphasize that seed SMs display a much higher environmental plasticity than storage compounds (e.g. oil and proteins). Last, we identified flavonols as the most plastic metabolic class, revealing highly variable accumulation according to the environmental conditions and/or the genotype. This work highlights the predominant effect of the environment on the regulation of the seed-specialized metabolome, with a potential impact on the seed quality of camelina and other crop species.Significance statementSeeds produce a myriad of Specialized Metabolites (SMs) with an essential role in the interaction of plants with their environment.

“…April in the Upper Midwest (Walia et al, 2018). Flowering of no other crops in this region is so early; even winter canola (Brassica napus L.), which lacks sufficient hardiness to be grown commercially in the region, begins flowering much later than pennycress and camelina (Eberle et al, 2015).…”

“…Although pennycress and camelina are primarily self‐pollinated (Walsh et al., 2012; Sedbrook et al., 2014; Vollmann and Eynck, 2015), flowers of both species are visited frequently by insects (Eberle et al., 2015; Groeneveld & Klein, 2013; Rizzitello, 2016). Anthesis of autumn‐sown pennycress and camelina is as early as late April in the Upper Midwest (Walia et al., 2018). Flowering of no other crops in this region is so early; even winter canola ( Brassica napus L.), which lacks sufficient hardiness to be grown commercially in the region, begins flowering much later than pennycress and camelina (Eberle et al., 2015).…”

Flowers of field pennycress (Thlaspi arvsense L.) and winter camelina (Camelina sativa (L.) Crantz.) produce abundant pollen and nectar in early spring and thereby may be valuable for pollinators. Insects observed in field plots of these flowers were classified into seven easily identifiable groups (bumblebee, honeybee, solitary bee, butterfly/moth, beetle, fly and other) and monitored for 2 years at three sites in the Upper Midwest region of the USA. Average seasonal observations across years and sites varied from 1.6 to 5.3 total insects/min for field pennycress and 1.4 to 4.5 insects/min for winter camelina. Lowest visitation rates occurred in central Iowa and highest rates in south‐eastern Minnesota for both crops. Multiple regressions showed that visitation rates for specific insect groups were correlated poorly but significantly (p < .10) with select variables. For example, in field pennycress, visitation by combined bumblebees and honeybees (Apidae) increased with greater air temperature at sampling time and annual site precipitation, whereas fly (Diptera) visitation was related to sampling date and flower cover. Similarly, in winter camelina, solitary bees were linked to increasing air temperature at sampling time and annual site precipitation, whereas flies were correlated with wind speed and flower cover at sampling. Field pennycress and winter camelina are reliably attractive to beneficial pollinating insects across a wide geographic region, but visitation rates and proportional representation of various insect groups depended on a range of site and weather characteristics.
