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].

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

Abstract Ornamental plants are used to improve the aestheticquality of urban and rural landscapes, recreational areas, interiorscapes and commercial sites. Any negative effects of salts on ornamental plant growth have to be taken into consideration mainly for their negative influences on aesthetic value of ornamental plants. The research was conducted to determine the effects of different concentrations of calcium nitrate on some stress parameters (i.e. leaf relative water content, chlorophyll, stomatal conductance, ion leakage in the leaf tissues) and some plant growth parameters (total leaf number, number of dried leaf, main stem diameter, plant crown diameter, plant height, fresh and dry weight of root) of ornamental kale (Brassica oleracea L. var. acephala) plant grown under saline conditions. Four doses of NaCl (NaCl1:30, NaCl2:60, NaCl3:90, NaCl4:120 mM), three doses of Ca(NO3)2 (CaN1:5, CaN2:10, CaN3:15 mM), groups combined together in all doses of NaCl and Ca (NO3)2 and control (NaCl0:0 + CaN0:0) were applied into the pots with three replications. Ca (NO3)2 was applied to the leaf surface of the plants in the pots to be applied as Ca (NO3)2 spray. When the plants reached a certain maturity (two weeks after transfer to the pot), salt stress applications were started. Ca (NO3)2 treatments have applied after one week from salt stress applications. Calcium nitrate treatements applied under salt stress conditions had positive effects and increasing in effect on all parameters examined except for chlorophyll and ion leakage in leaf tissues of the plant. With increasing in calcium nitrate concentration, morphological and physiological characteristics of plants were observed increases in general. It was concluded that the increase of the number of leaves by NaCl2+CaN3 application can be minimized with CaN3 (with 15 mM Ca (NO3)2) stress caused by 60 mM salt concentration According to the results of the research, calcium nitrate applications can be recommended for ornamental kale plants grown under salt stress conditions especially limiting the negative effects of stress and to minimize such damage.
