“…Materials were grown from May to the beginning of July 2016. Prior to sowing, seeds were treated with 2.5% (v/v) commercial bleach for 5 min followed by 100 ppm gibberellic acid (Duchefa Biochemie, Haarlem, The Netherlands) solution for 24 h [19]. Seeds were then sown in individual seedling trays filled with commercial Neuhaus Humin-substrat N3 substrate (Klasmann-Deilmann Gmbh, Geeste, Germany), and placed under long day conditions (16/8 h, T = 25 • C).…”

“…Three pots per population were transplanted, with 25 plants each. The plants were fertigated using a drip irrigation system, with the following final concentration for the main cations and anions in the watering: 11.47 mM NO 3 − , 1.00 mM NH 4 + , To prepare the samples, plants were harvested at the appearance of the first flower bud and before stem elongation [19], and only leaves without stems were used. While this wild vegetable is commonly harvested before flowering, taking the appearance of flower bud as reference allowed us to ensure the same phenological stage in all populations.…”

Wall rocket is a leafy vegetable with pungent flavor related to the presence of isothiocyanates (ITCs). Despite interest in it as a crop of high organoleptic quality, the variability of the volatile profile in the species remains unknown. Twenty-four populations grown under a greenhouse were evaluated. A considerable diversity for the total levels of volatiles was found, providing information of the aroma intensity among accessions. ITCs represented the main fraction. Allyl ITC was the main compound, and levels showed up to 6-fold difference among populations. The esters fraction was mainly represented by cis-3-hexenyl isovalerate and cis-3-hexenyl butyrate, with 20-fold differences among populations. Additionally, the content in sinigrin was evaluated as main GSL in wall rocket. Differences reached up to 13-fold. These results suggest that some populations can be used to develop highly pungent varieties, whereas some others can be selected for mild-pungent varieties, as it is the case of DER045 with low levels of ITCs and high in esters. The presence of several ITCs in the profile also suggested the presence of other novel GSLs. Overall, the work increases the knowledge in the variability of wall rocket for the volatile profile and sinigrin accumulation, a starting point for future breeding programs.

“…Thus, two independent growing cycles were evaluated: the late autumn-winter season (hereafter called the winter season) and late winter-early spring season (hereafter called the spring season). In each cycle, assays were simultaneously carried out in two cultivation systems: a heated glasshouse (39 • First of all, seeds were treated with a pre-germinative treatment in order to break the possibly secondary dormancy and increase the germination uniformity [30]. Thus, seeds were treated with commercial sodium hypochlorite 2.5% (v/v) for 5 min plus gibberellic acid 100 ppm (Duchefa Biochemie, Haarlem, The Netherlands) for 24 h. Treated seeds were sown in commercial Neuhaus Humin-substrat N3 substrate (Klasmann-Deilmann Gmbh, Geeste, Germany) and placed in a growing chamber with long day conditions (16/8 h, 25 • C) for two days.…”

Wall rocket (Diplotaxis erucoides) is a wild vegetable with the potential to become a crop of high antioxidant quality. The main bioactive compounds include ascorbic acid (AA), sinigrin, and a high content of total phenolic compounds (TP). It also accumulates nitrates. Since these compounds are affected by environmental conditions, adequate crop management may enhance its quality. Eleven accessions of wall rocket were evaluated under field and greenhouse conditions during two cycles (winter and spring) and compared to Eruca sativa and Diplotaxis tenuifolia crops. The three species did not differ greatly. As an exception, sinigrin was only identified in wall rocket. For the within-species analysis, the results revealed a high effect of the growing system, but this was low among accessions. The highest contents of AA and TP were obtained under field conditions. In addition, the levels of nitrates were lower in this system. A negative correlation between nitrates and antioxidants was determined. As a counterpart, cultivation in the field–winter environment significantly decreased the percentage of humidity (87%). These results are of relevance for the adaptation of wall rocket to different growing conditions and suggest that the field system enhances its quality. The low genotypic differences suggest that intra-species selections in breeding programs may consider other aspects with greater variation.

“…The experiment was performed during the months of May to July 2016, at the UPV (39 • 29' 00" N; 0 • 20' 27" W). Seeds were treated with 2.5% commercial sodium hypochlorite plus 100 ppm gibberellic acid (Duchefa Biochemie, Haarlem, The Netherlands) solution [21]. Treated seeds were sown in seedling trays (112 cells, 22 mL each) using commercial Neuhaus Humin-substrat N3 substrate (Klasmann-Deilmann Gmbh, Geeste, Germany), placed for one week in a growing chamber with long-day conditions (16/8 h, 25 • C), and then moved to a glasshouse.…”

“…Analyses were performed in triplicate. The AA content was measured from fresh material by using the high performance liquid chromatography (HPLC) technique, according to Guijarro-Real et al [21]. Briefly, 1.0 g was homogenated with 5 mL 3.0% (w/v) cold meta-phosphoric acid solution and filtered through a 0.22 µm PVDF filter (Teknokroma, San Cugat del Vallès, Spain).…”

Wall rocket is a wild vegetable with interest to become a crop. However, the information regarding morphological variability in the species is scarce, despite the interest it has received for breeding programs. In addition, evaluating the phytochemical composition can also be useful for developing materials of a high quality. In this study, forty-four populations were evaluated for selected morphoagronomic traits and contents in ascorbic acid (AA), total phenolics (TP), and nitrates (NO3−). Wall rocket plants had, on average, an intermediate growth habit and a good response to transplant. Moderate variability, mainly for size-related traits, was found, with low to moderate heritability estimates (H2 < 0.35). A Principal Component Analysis revealed that some materials may be selected for differenced traits. On the other hand, wall rocket materials had, on average, high contents in AA (53 mg 100 g−1) and TP (116 mg CAE 100 g−1) but also accumulated high levels of NO3− (891 mg 100 g−1). Significant positive correlations were found for AA and TP, which could be exploited for increasing the antioxidant activity and properties of the final product. We provide new information on the variation of wall rocket for traits of morphological and phytochemical interest, which together with other traits, such as the profile of glucosinolates, can be useful for the selection of materials in future breeding programs.
