“…Many studies have confirmed the effects of storage duration and conditions on the quality of broccoli heads (Starzyńska et al 2003, Hasperué et al 2015, Vale et al 2015. According to Balouchi et al (2011), of the five broccoli cultivars compared in their study, after 40 days of storage at 0°C, four cultivars exhibited a significant increase in phenolic content, while a fall was observed in one of the cultivars.…”

“…According to the authors, the level of the acids increased until the fifth day of storage, and then it decreased to the lowest value after 12 days. In the research by Starzyńska et al (2003), when broccoli heads were stored at 5°C there was a significant increase in the concentration of phenolic compounds after 7 and 10 days, both in the heads packed in commercial polymeric film and in non-packed heads. The factors considerably affecting both the phenolic and flavonoid contents were: controlled atmosphere of storage (1-2°C, 85-90% RH, 10% O 2 and 5% CO 2 ) (FernandezLeón et al 2013), cultivation conditions -organic or conventional (Valverde et al 2015), and fertilization (Vallejo et al 2003).…”

Biostimulants are commonly used in horticulture, primarily to increase yield quantity and quality, as well as plant tolerance to stress. The purpose of the study was to determine the effect of amino acid-based biostimulants and amino acids in combination with Ascophyllum nodosum filtrate, applied during the growing season on the phenolic content in broccoli heads both after harvest and after long storage in a cold store. The seedlings were planted in mid-July, and heads were harvested from September to October in each year of the study. Ascophyllum nodosum filtrate at a concentration of 1% was used during seedling production. The plants were watered with biostimulants twice, in the fourth and fifth week after sowing. They were also sprayed with amino acid-based biostimulants (1.5 dm 3 ha -1) three times, i.e. after the second, fourth and sixth week after planting. The biostimulants were not used in the control treatment. After harvest, the heads were stored for three weeks in a cold store at 1-2°C and 95% RH. Chemical analyses of total phenolic, caffeic, ferulic and sinapic acids, and of quercetin and kaempferol were carried out on samples of fresh broccoli and after the first, second and third week of storage. It was found that the application of biostimulants resulted in a significant increase in the total phenolic content, sinapic acid content, as well as quercetin content. Both in the control treatment and in the plants treated with the biostimulants, the concentration of all the tested phenolic compounds increased with the duration of storage.Ke y wor d s: amino acids, Ascophyllum nodosum filtrate, Brassica oleracea var. italica, kaempferol, phenolic acids, quercetin

Background: Recent inquiries into high-quality foods have discussed the importance of the functional aspects of foods, in addition to traditional quality indicators such as color, firmness, weight, trimming loss, respiration rate, texture, and soluble solid content. Recently, functional Chinese cabbage, which makes up a large portion of the vegetables consumed in Korea, has been identified as an anticancer treatment. However, the investigation of practical issues, such as the effects of storage conditions on quality indicators (including functional compounds), is still limited. Purpose: We reviewed various studies on variations in the quality indicators and functional compounds of Chinese cabbage in response to different storage environments, focusing on storage temperature and storage period. In particular, we emphasized the effect of storage temperature and storage period on glucosinolate (GSL) levels, in order to provide guidelines for optimizing storage environments to maximize GSLs. Additionally, we used response surface methodology to propose experimental designs for future studies exploring the optimal storage conditions for enhancing GSL contents. Review: Large variations in quality indicators were observed depending on the cultivar, the type of storage, the storage conditions, and the harvest time. In particular, GSL content varied with storage conditions, indicating that either low temperatures or adequate air composition by controlled atmospheric storage may preserve GSL levels, as well as prolonging shelf life. Even though genetic and biochemical approaches are preferred for developing functional Chinese cabbage, it is important to establish a practical method for preserving quality for marketability; a prospective study into optimal storage conditions for preserving functional compounds (which can be applied in farms), is required. This may be achievable with the comprehensive meta-analysis of currently published data introduced in this review, or by conducting newly designed experiments investigating the relationship between storage conditions and the levels of functional compounds.

IntroductionProper growth and development of plants depends on an efficient defense system, mainly against reactive oxygen species. Studies on how plant genotypes respond to all kind of stresses indicate a similar mechanism of adaptation to unfavorable environmental conditions. These reactions are mostly connected with neutralizing free radicals, particularly reactive oxygen species (ROS) which frequently appear as the effect of different stress factors [1][2][3]. Many experiments indicate significance changes in the enzymatic and non-enzymatic antioxidant system during environmental stresses in plant tissues. The most active in this respect are usually the classified enzymes: catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) as well as chemical compounds such as glutathione, ascorbic acid or different polyphenols [4,5]. It is well established that the mechanisms of tolerance to chilling, freezing, drought or high salinity include the action of common genes. For this reason chilling transplants before planting might result in a better adaptation of plants cultivated from such transplants to various stresses via a well-defined increase in the antioxidant activity system in particular plant organs [6,7]. In recently carried out investigations that were focused on the reaction of wild species or cultivated plant cultivars to abiotic stresses, only early vegetative stages of development in the studied genotypes were applied [7,8]. Moreover, these experiments were mainly carried out in strictly controlled conditions. As a rule, neither the natural environment of plant growth nor the stage of full generative development was considered.The Brassica oleracea L. var. italica that was used in the presented experiment is a vegetable of great economical value, and in Europe it is grown on a large scale that could be compared to that of the cauliflower. Broccoli flower buds contain an elevated level of health-promoting substances, which are active during the neutralization of free radicals [9,10]. A crucial example of such is glutathione, a non-enzymatic hydrophilic antioxidant that commonly occurs in plants belonging to the Brassicaceae family. This thiol compound is an important substrate of the enzymatic defense system in the cytoplasm and in the chloroplasts of plant cells. Because of its anticarcinogenic functions it is very important in the human diet. In some cultivars of broccoli the glutathione content may exceed 200 nmol g −1 of fresh weight [11]. The cultivar italica of B. oleracea can optionally be planted from transplanted seedlings in spring, summer or autumn, but this practice sometimes requires storage of the transplant material. The storage may be necessary because of unfavorable weather conditions. For that reason offering an efficient way AbstractThe study was designed to determine the possible relationship between Brassica oleracea var. italica seedlings stored at 2°C in the dark for seven and fourteen days, respectively, and the level of certain antioxidant parameters in particular organs. ...
