Kales (Brassica oleracea acephala group) are important vegetable crops in traditional farming systems the Iberian Peninsula. They grown throughout year to harvest their leaves and flower buds. The glucosinolate content of kales is dependent upon environmental factors, plant part examined, phenological stage growth, level insect damage. objectives this study were evaluate changes total individual concentrations during development determine if significant variation levels can be explained by...

Abstract Introduction – Brassica vegetables have been related to the prevention of cancer and degenerative diseases, owing their glucosinolate phenolic content. Objective Identification glucosinolates, flavonoids hydroxycinnamic acids in representative varieties kale, cabbage leaf rape. Methodology One local variety each crop was evaluated this study using a multi‐purpose chromatographic method that simultaneously separates glucosinolates phenolics. Chromatograms were recorded at 330 nm for...

Due to its biennual life cycle Brassica oleracea is especially exposed seasonal changes in temperature that could limit growth and fitness. Thermal stress plant growth, leaf development photosynthesis. We evaluated the performance of two local populations B. oleracea: one population cabbage (B. capitata group) kale acephala under limiting low high temperatures. There were differences between crops how they responded stress. Low temperatures affect photosynthesis fresh weight. Stomatal...

ABSTRACT Glucosinolates (GSLs) are secondary metabolites found in Brassica vegetables that confer on them resistance against pests and diseases. Both GSLs glucosinolate hydrolysis products (GHPs) have shown positive effects reducing soil pathogens. Information about their vitro biocide is scarce, but previous studies sinigrin associated allyl isothiocyanate (AITC) to be biocides. The objective of this work was evaluate the 17 GHPs leaf methanolic extracts different GSL-enriched crops...

Brassica oleracea crops are exposed to seasonal changes in temperature because of their biennial life cycle. Extreme temperatures (cold and heat) affect the photosynthetic activity yield cabbage (B. capitata group) kale acephala group). We studied relationship among antioxidant defenses, photosynthesis, under extreme both crops. Under these conditions, plants increase responding an increment reactive oxygen species (ROS). The accumulation ROS chloroplasts decreases chlorophyll content...

A new more sustainable agricultural system needs to be developed increase production without compromising human and animal health preserving essential resources, such as soil, water diversity. Bio-inoculants can a tool favor this transition, they replace or complement agrochemicals that do not meet the above premises. generated from endophytic filamentous fungi mycorrhizal fungi, whether used individually, in combination with each other microorganisms, stand out for their potential. This...

Abstract Brassica foods are among the top 10 economic crops in world (i.e. broccoli, kale, cauliflower and Chinese cabbage). These vegetables have been identified as important components of a healthy diet because their high levels nutrients health‐promoting phytochemicals phenolics, glucosinolates, vitamins minerals). Epidemiological studies shown that increased consumption is strongly associated with reduced risk degenerative diseases, cancer, cardiovascular disease immune dysfunction....

The study of domestication contributes to our knowledge evolution and crop genetic resources. Human selection has shaped wild Brassica rapa into diverse turnip, leafy, oilseed crops. Despite its worldwide economic importance potential as a model for understanding diversification under domestication, insights the number events initial crop(s) domesticated in B. have been limited due lack clarity about or feral status conspecific noncrop relatives. To address this gap reconstruct history rapa,...

The glucosinolate profile of leaves and seeds 33 Brassica napus L. crops, including leafy forage, rutabaga, oilseed was compared by high-performance liquid chromatography to investigate the relation between consumable product each crop profile. Glucosinolate concentration higher in than leaves, varying from 3.8-fold crops 7.1-fold root vegetable crops. Aliphatic glucosinolates predominated both organs. In seeds, aliphatic represented 91% 94% different groups, whereas there more variation....

Glucosinolates are major secondary metabolites found in the Brassicaceae family. These compounds play an essential role plant defense against biotic and abiotic stresses, but more interestingly they have beneficial effects on human health. We performed a genetic analysis order to identify genome regions regulating glucosinolates biosynthesis DH mapping population of Brassica oleracea. In obtain general overview regulation whole plant, analyses were three organs where synthesized (leaves,...

Abstract Brassica oleracea var. acephala (kale) is a cruciferous vegetable widely cultivated for its leaves and flower buds in Atlantic Europe the Mediterranean area, being food of great interest as "superfood" today. Little has been studied about diversity endophytic fungi genus, there are no studies regarding kale. In this study, we made survey present roots six different Galician kale local populations. addition, investigated whether presence endophytes was beneficial to plants terms...

Brassica crops include important vegetables known as "superfoods" due to the content of phytochemicals great interest human health, such glucosinolates (GSLs) and antioxidant compounds. On other hand, Trichoderma is a genus filamentous fungi that includes several species described biostimulants and/or biological control agents in agriculture. In previous work, an endophytic strain hamatum was isolated from kale roots (Brassica oleracea var. acephala), describing its ability induce systemic...

This study aimed to standarize a protocol for obtaining bioactive extract from broccoli (Brassica oleracea var. italica) crop residues, that is suitable application on an industrial scale and effective in reducing plant disease incidence. For this purpose, the influence of several extraction factors glucosinolate (GSL) content was studied with leaves collected two conventional fields organic fields. The analysis showed lyophilization had no GSL content. Storage material under different...
