Drought is one of the major challenges global crop production, and its severity increasing because climate change. This abiotic stress an important target for Brassica species, which are generally grown in arid semi-arid climates. study was conducted to investigate effects water deficit on a set accessions belonging core collection EU H2020 BRESOV project, represented by oleracea L. crops complex species (n = 9). In particular, variation amount profile glucosinolates (GLSs) compounds...

The gene flow from Brassica oleracea L. wild relatives to B. vegetable crops have occurred and continue occur ordinarily in several Mediterranean countries, such as Sicily, representing an important hot spot of diversity for some them, broccoli, cauliflower kale. For detecting exploiting the forgotten alleles lost during domestication processes crops, attention has been pointed individuation specific markers individuating genotypes characterized by hypertrophic inflorescence traits marker...

Nowadays, there is a global surge in interest surrounding novel foods, particularly sprouts, microgreens, and baby leaves, attributed to their rich content of bioactive compounds, such as phenolic derivatives, glucosinolates, vitamins. This study delves into the impact exogenously applied melatonin on foods derived from Brassica oleracea L. Two distinct cultivars broccoli (Brassica var. italica Plenck), namely Sicilian sprouting (Broccolo nero) commercial variety (Cavolo Broccolo Ramoso...

Drought stress significantly affects plant growth, productivity, and yield by inducing morphological, physiological, biochemical changes. This study evaluates exogenous melatonin effects on agronomic traits of two broccoli varieties (Brassica oleracea L. var. italica Plenck) at the baby-leaves stage under drought stress. The used were Sicilian sprouting black broccoli, Broccolo nero (BR), commercial one, Cavolo Ramoso Calabrese (CR). experiment was conducted in a cold greenhouse Catania,...

Drought tolerance of Brassica crops can be genetically improved by establishing plant ideotypes with yield responses associated agronomic traits and biochemical markers. The objective this study was to compare 20 oleracea L. accessions grown under two different water treatments (100% 35% reintegration evapotranspiration irrigation) select potential tolerant genotypes for organic cultivation based on several parameters measured in response drought stress. Significant differences were...
