A two-factorial field experiment was performed in a randomized block design with three replications in 2010-11 in the Experimental Garden of the University of Warmia and Mazury in Olsztyn, to determine the effect of seedling planting time on the concentrations of mineral compounds in basil leaves. Plot area was 1.2 m2. The experimental factors were: (1) plants of sweet basil, purple (purpurascens) basil, and cinnamon basil, and (2) time of planting basil seedlings. The concentrations of macroelements (total nitrogen, phosphorus, potassium, magnesium, calcium, and sodium) and microelements (iron and copper) were determined in basil leaves. The content of total nitrogen, phosphorus, potassium, magnesium, calcium, and sodium in basil leaves depended on the cultivar. Cinnamon basil contained the highest concentrations of total nitrogen, phosphorus, magnesium, and calcium, whereas sweet basil had the highest content of potassium and sodium. The time of planting seedlings had a significant effect on the iron content of basil leaves, which was higher in plants that developed from seedlings planted on 19 May.
The aim of this study was to compare chemical composition of lemon balm and basil herbage grown in containers under fluorescent lamps (FL) and LED modules (LEDs). There were significant differences in the response of the species for the applied source of light. The content of essential oils was greater in basil herbage under fluorescent lamps, whereas the content of essential oils in lemon balm herbage was greater under LED lamps. The basil and lemon balm plants were characterised by high content of fructose and glucose and by very low content of sucrose. There were no significant differences in the nitrates content in basil and lemon balm herbage grown under either source of light. Both the basil and lemon balm herbage were found to have higher content of macroand micronutrients when they were grown under LEDs compared with fluorescent lamps. It can be concluded that the chemical composition of lemon balm and basil herbage was very varied and dependent on both the light and the species.
The study was carried out in 2002 and 2003. The experimental material was basil plants cultivated in the field for a bunch harvest, using for plant covering perforated foil and polypropylene unwoven cloth. The control object was basil grown without covering. The covers tested in the experiment had a significant influence on the yielding of basil cultivated for a bunch harvest. The highest yield was obtained when polypropylene unwoven cloth was used. Basil plants grown under polypropylene unwoven cloth were the highest (18.2 cm), had the biggest diameter (13.4 cm) and the largest leaves (5.9 cm long and 3.3 cm wide). Using covers (perforated foil and polypropylene unwoven cloth) caused a decrease of dry matter content in the yield of basil, in comparison with the plants grown without covering.The covers used in the study caused a decrease of nitrogen, potassium, calcium and magnesium in the basil yield, but did not decrease phosphorus and sodium content.
Doświadczenie dwuczynnikowe przeprowadzono w latach 2012-2014 w szklarni Katedry Ogrodnictwa Uniwersytetu Warmińsko-Mazurskiego w Olsztynie w układzie podbloków losowanych w trzech powtórzeniach. Pierwszym czynnikiem badawczym było sześć odmian botanicznych bazylii pospolitej: bazylia zielonolistna, tajska ‘Siam Queen’, grecka (drobnolistna) ‘Minette’, czerwonolistna, cytrynowa oraz cynamonowa. Drugim czynnikiem doświadczenia była uprawa roślin w doniczkach o zróżnicowanej pojemności oraz liczbie roślin: 0,7 dm3 z jedną rośliną w pojemniku; 3,0 dm3 z jedną rośliną w pojemniku; 3,0 dm3 z czterema roślinami w pojemniku. W kolejnych latach trzyletniego cyklu doświadczenia, między 22 a 24 lutego, w szklarni na stołach przesuwnych w zależności od objętości doniczek (0,7 dm3 i 3,0 dm3) ustawiono pojemniki wypełnione podłożem organicznym, w którego skład wchodził torf sfagnowy. Na podstawie przeprowadzonych badań wykazano, że spośród uprawianych odmian botanicznych bazylia grecka i tajska były niższe od pozostałych, a bazylia grecka posiadała ponadto najwięcej rozgałęzień. Zastosowanie w uprawie bazylii pospolitej doniczek o pojemności 3,0 dm3, w których uprawiano po jednej roślinie, powodowało istotne zwiększenie masy i liczby rozgałęzień.
Genetic relatedness among basil accessions including six species of Ocimum (O. basilicum L., O. americanum L., O. x citriodorum L., O. minimum L., O. gratissiumum L., O. tenuiflorum L.) and six botanical varieties or cultivars of O. basilicum L. [var. basilicum L. cv. Genovese, var. basilicum L. cv. Sweet Basil, var. difforme Benth., var. purpurascens Benth., cv. Dark Opal, and var. thyrsiflorum (L.) Benth.] were analyzed by random amplified polymorphic DNA (RAPD) markers. Five primers were used for amplification. They yielded a total of 102 easily scorable polymorphic markers. Jaccard indices were calculated and phylogenetic relationships were determined by neighbor-joining cluster analysis. Different Ocimum species were clearly divided into separate clusters with the exception of O. minimum accessions, which clustered together with O. basilicum accessions. In addition to morphological, chemical and crossability data, RAPD analysis can be a useful tool for resolving existing problems in identification and classification of basils.
Bazylia pospolita (Ocimum basilicum L.) jest rośliną jednoroczną, z rodziny jasnotowatych (Lamiaceae), której świeże i suszone ziele stosowane jest w przemyśle kosmetycznym, farmakologicznym, perfumeryjnym oraz w gastronomii. Jako gatunek pochodzący z klimatu ciepłego ma wysokie wymagania termiczne. Zapobiegając działaniu niskiej temperatury, szczególnie w okresie wiosennych przymrozków, bazylię pospolitą uprawia się z rozsady, jednak należy ustalić optymalny termin wysiewu nasion, dla uzyskania odpowiedniej jakości i wielkości plonu surowca przyprawowego. W tym celu w latach 2010-2012 przeprowadzono doświadczenie polowe w układzie losowanych podbloków w trzech powtórzeniach. W szklarni wysiano nasiona czterech ekotypów bazylii pospolitej (zielonolistnej, czerwonolistnej, cynamonowej oraz cytrynowej) w dwóch terminach (30 marca i 14 kwietnia). Badaniu poddano plon świeżego i suchego ziela bazylii pospolitej, a następnie przeprowadzono ocenę składu chemicznego świeżego surowca przyprawowego, określając w nim zawartość: suchej masy, kwasu L-askorbinowego, cukrów ogółem i redukujących. Analizując wyniki badań wykazano, że uprawiane eko-typy Ocimum basilicum L. istotnie różnicowały wielkość plonu oraz skład ziela. Największym średnim plonem w toku trzyletnich badań charakteryzowała się bazylia cynamonowa, zaś najmniejszy średni plon ziela pozyskano z bazylii czerwonolistnej, której surowiec przyprawowy zawierał najmniej suchej masy, kwasu L-askorbinowego oraz cukrów ogółem. Najwięcej suchej masy oraz kwasu L-askorbino-wego zawierała bazylia zielonolistna, zaś największą zawartością cukrów ogółem charakteryzował się surowiec przyprawowy bazylii cynamonowej. Największą zawartością cukrów redukujących odznaczała się bazylia pospolita cytrynowa, a najmniejszą – bazylia zielonolistna. Analiza terminu siewu nasion w drugim oraz trzecim roku badań wykazała, iż wcześniejszy termin siewu istotnie zwiększał wielkość plonu oraz zawartość cukrów ogółem.
One of the most popular and usable Aromatic plants are kinds of Basilica (Ocimum sp., Lamiaceae). This genius has different characteristics in behavior germination. Biodynamic agriculture is a new science in the research and especially the position of stars and planet relative to each other, position of moon around the earth and seasonal change and Solar and lunar eclipses. We must demonstrate this theory. In this experiment, we want to record the effect of based on two calendars (biodynamic and Astronomic) on three ecotypes of Basilica seed germination. The base of this experiment was a randomized block design with three replications. We used 50 seeds in Falcon tube (value=15ml) and recorded the weight and value of seeds in tube. Then we added 5ml of water in tube and shacked after moisturized and control and recorded the Mucilage value and another behavior of seed germination in lab condition. Results showed that different position of some planets such as moon and Mars and Jupiter had the highest effect, positive and significant effect on mucilage percent (p>95%), germination speed and length of root. Therefore, we could express the lunar position had the highest effect on root length of local type and the lowest effect on purple basil. Mucilage percentage of seed coat in green basil had the highest content relative to another ecotype and this content was significant (p>95%). Thus, the best suggestion for the produce of mucilage from the basil seeds, the best time is the first quadrature of the moon.
Mycorrhizal fungi, algae and cyanobacteria are some of the most important soil microorganisms and major components of a sustainable soil-plant system. This study presents for the first time evidence of the impact of green alga and cyanobacterium solely and in combination with arbuscular mycorrhizal fungi (AMF) on plant-antioxidant capacity. In order to provide a better understanding of the impact of AMF and soil microalgae on Ocimum basilicum L. performance, changes in the pattern and activity of the main antioxidant enzymes (AOEs), esterases and non-enzymatic antioxidants including phenols, flavonoids, ascorbate, and α-tocopherols were evaluated. The targeted inoculation of O. basilicum with AMF or algae (alone and in combination) enhanced the antioxidant capacity of the plants and the degree of stimulation varied depending on the treatment. Plants in symbiosis with AMF exhibited the highest antioxidant potential as was indicated by the enhanced functions of all studied leaf AOEs: 1.5-, 2- and more than 10-fold rises of superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione reductase (GR), respectively. The greatest increase in the total esterase activity and concentration of phenols, flavonoids and ascorbate was marked in the plants with simultaneous inoculation of mycorrhizal fungi and the green algae. 2,2-diphenyl-1-pycril-hydrazyl (DPPH) free radical scavenging method and ferric reducing antioxidant power (FRAP) assay proved the increased plant antioxidant capacity after co-colonization of green algae and mycorrhizae.
The objective of a study conducted in the years 2007–2008 was to determine the nitrate content of the edible parts of vegetables and spice plants. The analyzed materials consisted of the following species: tomatoes, carrots, sweet basil and marjoram grown in the field, and tomatoes and chili peppers grown in a plastic tunnel. The experiment comprised different cultivation methods, sowing and planting dates, and fertilization levels. Among the analyzed cultivars of field-grown tomatoes, increased nitrate concentrations were observed in the fruits of cv. Złoty Ożarowski. Similar results were noted when eight tomato cultivars were grown in an unheated plastic tunnel. The fruits of cv. Bawole Serce had the lowest nitrate content, compared with the remaining tomato cultivars. Supplemental fertilization of tomato plants grown under cover significantly contributed to nitrate accumulation. The fruits of chili peppers grown in a plastic tunnel had a very low nitrate content. As regards marjoram, the highest nitrate concentrations were reported for the second date of sowing. The average nitrate content of carrot storage roots did not exceed the maximum permissible levels. Supplemental fertilization contributed to an insignificant increase in the N-NO3 content of carrot roots.
The study aimed to determine agronomic characteristics and essential oil components of different basil ecotypes in semi-arid climatic conditions of South Eastern Anatolia, Diyarbakir, Turkey. Two-year harvest data about fresh and dry herb yield, dry leaf yield, essential oil content and its components from the plants of year 2015 and 2016 was analyzed in this study. Essential oil components were detected by gas chromatography/ mass spectrometry (GC/MS). The resulting outcomes demonstrated that both ecotypes and harvests had important effects on fresh and dry herb, dry leaf yield and essential oil contents of sweet basil. The highest dry leaf yield was noted from green leafy ecotypes and from second harvest stage. Twenty-three constituents were detected in the essential oil of O. basilicum ecotypes. The main components of basil essential oil were linalool, methyl chavicol, neral, geranial and methyl cinnamate that differed according to ecotypes and harvests during experimental years 2015 and 2016. Purple leafy basil ecotypes were determined as linalool rich, while greenish leaf ecotypes were abundant in methyl chavicol. Silbe – green ecotype contains higher neral and geranial levels than the other ecotypes. It was concluded that basil plant could be grown successfully and harvested two or more times to prefer for maximum dry leaf yield and essential oil contents under semi-arid climatic conditions.
