Brassica Oleracea L

Some new foods (sprouts, microgreens and baby leaf) of the brassica genus are appreciated for their nutritional and nutraceutical values. The aim of this experimental trial was to improve the nutraceutical traits of these foods by evaluating the effects of the climatic condition, genotype, and plant growth stage on the development of greater quality in relation to these new foods. The morphometric and glucosinolates (GLSs) traits of three traditional Italian cultivars of Brassica oleracea crops, such as broccoli (B. oleracea var. italica), namely the traditional Sicilian landrace ‘Broccolo Nero’ (BN) and the commercial ‘Cavolo Broccolo Ramoso Calabrese’ (CR), as well as the commercial kale cultivar ‘Cavolo Laciniato Nero di Toscana’ (CL) (B. oleracea var. acephala DC.), were evaluated in an unheated greenhouse in Catania during the end of 2019 and the beginning of 2020. Plant growth was studied at different phenological stages—from seeds to sprouts, microgreens, and baby leaves—over two growing cycles, one in autumn–winter and the other in spring–summer. ‘Broccolo Nero’ (BN) broccoli showed more rapid growth and biomass production than the other two cultivars evaluated (i.e., weight, hypocotyl length, and leaf width). The GLS profile varied significantly (p < 0.05), in relation both to plant’s growth stage and to genotype. The highest amount of glucoraphanin was detected for BN microgreens and baby leaves, about 8 µmol g−1 d.w., whereas glucobrassicin and its related derivatives were about 14 µmol g−1 d.w. in microgreens and baby leaves of CL and about 15 µmol g−1 d.w. and 10 µmol g−1 d.w. for glucoraphanin in CR, respectively. These new foods can also be produced at home with simple and cheap equipment

Blackleg, also known as Phoma stem canker, caused by Leptosphaeria maculans (Phoma lingam), is one of the most serious diseases of canola worldwide. In this study, the mean disease severity (Ds) and incidence (Di) of canola cv. Westar plants infected at the cotyledon, three-leaf, and six-leaf stages by pycnidiospores of L. maculans were monitored in the greenhouse after infection of the plants under field conditions in two successive years and associated with meteorological data during infection time. Pearson's correlation coefficient showed that total rainfall per week (R) was significantly correlated to Ds on plants infected at the cotyledon, three-leaf, and six-leaf stages, and average maximum temperature per week (Tmax) only showed significant correlation with plants infected at the cotyledon and six-leaf stages. These results also indicated that there is correlation between Di and R for plants infected at all three growth stages. A nonlinear model was developed to evaluate the combined effects of R and Tmax on Ds. The best model comprised monomolecular function and β probability density function for plants infected at the above three growth stages. Parameters, including maximum potential for Ds at a given rainfall (dmax), rate of changes with respect to rainfall (k), constant of integration (B), maximum potential for Ds with respect to Tmax (e), rate of increase with increasing Tmax to optimum (n), and rate of decrease as Tmax increased and passed the optimum Tmax (p), were estimated for plants infected at the above three growth stages. The effect of plant growth stage was characterized by differences in the upper limit parameter a. This parameter was greater for the plants infected at the cotyledon stage than for plants infected at the other two stages. The estimate of parameter k was the same for the plants infected at the cotyledon and three-leaf stages. This parameter was much lower for the plants infected at the six-leaf stage compared with two other stages. The logistic model could describe the disease incidence with respect to R slightly better than the other two models in the plants infected at all three growth stages. Based on the model, upper-limit estimate (dmax) was ≈100, 94.4, and 88.8% in the plants infected at cotyledon, three-leaf, and six-leaf stages, respectively. Di increased until rainfall reached ≈18, 10, and 13 mm/week and became constant in the plants at cotyledon, three-leaf, and six-leaf stages, respectively. Effects of plant growth stage on the rate of change with respect to R (parameter k) were lower in the plants infected at cotyledon than at the other two stages. The accuracy of the nonlinear models suggests that they could be used to develop a comprehensive model to evaluate epidemics of blackleg based on pycnidiospores as sources of inoculum. However, additional years of data collection should improve model fit and evaluation of introduced models and contribute to the development of a more robust predictive model.

The inheritance of the three glucosinolate components, goitrin, volatile isothiocyanates and thiocyanate ion, was studied in cabbage (Brassica oleracea L. ssp. capitata L.) plants obtained from various crosses between two moderate inbred lines, one selected for low, the other for high goitrin content. While all three glucosinolate components showed a strong heterosis towards lower concentrations, maternal effect in inheritance was observed for goitrin only. Inheritance of both goitrin and volatile isothiocyanates was controlled by four to six genes, whereas three to five genes were involved in thiocyanate ion. Estimates of broad-sense heritability were 35% for goitrin, 39% for volatile isothiocyanates and 80% for thiocyanate ion. Evidence suggests that some of the genes controlling inheritance of goitrin and volatile isothiocyanates are linked.Key words: Glucosinolate, cabbage, glucosinolate inheritance, Brassica

Brassica Oleracea L

Background: Aiming to increase the productivity and achieve production levels that meet the market demands, agriculture makes use of pesticides and fertilizers. Fertilizers are natural or artificial substances that contain chemical elements and physical proprieties that enhance plant growth and productivity [1]. However, the addition of fertilizers has generated environmental impacts that jeopardize the sustainability of agricultural ecosystems in the medium and long term [2]. Fertilizers are associated with eutrophication of rivers and lakes [2], soil erosion [3], among others. The organic agriculture is an alternative for the use of additives, which aims to enhance the efficient use of nonrenewable natural resources, and utilization of renewable natural resources and biological processes aligned to biodiversity, the environment, economic development and quality of human life [4]. The use of homeopathy for the cultivation of plants is into the organic agriculture. Homeopathic medicines can lead to greater plant growth, the elimination of pests and soil enrichment, without presenting environmental impacts, or damage to the consumer or for the handler. Aim: The objective of this study is to find on the homeopathic medicine an alternative method for the use of fertilizers in order to increase the germination of broccoli (Brassica oleracea L. var. Italica. Methodology: Seeds of broccoli will be treated with homeopathic medicines for phosphorus and gibberelic acid in the following method and scale 6cH, 30cH and 200cH, according with the 3rd edition of the Brazilian Homeopathic Pharmacopoeia. These seeds will be cultured on Petri dishes in a MS medium. The dilution and the agitation water on the same high dilutions above, are used as a growth control, in the same way, gibberelic acid, a hormone, widely used commercially as a fertilizer, is also used as control. The applications will be made six days a week. It will be conducted a seedlings count since the first days of germination and also will be measured the germination velocity and the hypocotyl and primary roots lengths. Results: A quickly, regular and more complete germination is expected when used homeopathic drugs. Rather than use substances harmful to human health, such as fertilizers but gaining it´s same efficiency with a less aggressive results for the plant and for who will eat it or work with agriculture [5-8].
