    Opis:
    Introduction and Objective. Carthamus tinctorius L. is commonly known as Safflower. C. tinctorius extracts and oil are important in drug development with numerous pharmacological activities in the world. This plant is cultivated mainly for its seed which is used as edible oil. For a long time, C. tinctorius has been used in traditional medicines as a purgative, analgesic, antipyretic and an antidote to poisoning. It is a useful plant in painful menstrual problems, post-partum haemorrhage and osteoporosis. Objective. The subject of this study is the seeds of Kazakhstan species of ‘Akmai’ safflower, collected in the flowering stage in Southern Kazakhstan. Volatile oil was carry out to study the component composition of Kazakhstan ‘AkMai’ safflower flowers. Materials and Method. Pale yellow oily extracts were obtain by varying the process parameters. The volatile oil obtained by hydrodistillation of the petals Carthamus tinctorius L. was analyzed by gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.175 % (v/w). 20 compounds representing 99.81% of the oil were characterized. The volatile oil was found to be rich in undecanoic acid, octane, 2-nonen -1-ol, hexadecanal, dodecanal, dec-2-en-1-ol, nonanoic acid, tetradecanoic acid, 2 pentadecanone, 6,10,14-trimethyl, 1,2-benzenedicarboxylic acid, isobutyl-beta-phenylpropionate, 1.3-cyclohexadiene, myrtenoic acid, octadecanoic acid, heneicosanoic acid, 2(3H)-furanone, 4,4-dipropylheptane, hexcosane,1-eicosanol, as well as heptocosane. Results. Volatile oil from the flowers of the Kazakhstan safflower species ‘Ak-Mai’ were investigated by GC/MS which allowed the detection of 20 compounds. Biologically active complex of the flower of the Kazakhstan safflower species ‘Ak-Mai’ was released for the first time by using this oil.

    Opis:
    By 2050, global crop demand is projected to rise by 60-110%. Crop yields have also been impacted by cli mate change in some nations, and these impacts are likely to continue. To prevent the influence of climate change on crop output, it is critical to adjust planting times in weather-related open fields to meet food security concerns. Present study was carried out at Experimental Farm of Faculty of Agriculture, Al-Azhar University, Assiut, Egypt, during two successive seasons, 2019 and 2020. It was aimed to study the effect of different sowing times (1st and 15th October, 1st and 15th November), and plant spacings (25, 20, and 15 cm) on growth, fruit yield, and oil production of caraway (Carum carvi L.) plants. The results showed that sowing caraway plants on 15th October with plant spacing of 25 cm gave the highest dry weight (72.6 g∙plant-1), fresh weight (266.15 g∙plant-1), seed yield (37.43 g∙plant-1), and oil yield (0.659 cm 3∙plant-1). The maximum umbels (50.83 number per plant) and essential oil (1.78%) were also recorded in the plants receiving same treatment. On the other hand, plants sown at 15th November with spacing of 15 cm exhibited the minimum values of recorded traits. While the highest value of plant height gave with sowing caraway plants on 15th October with plant spacing of 15 cm (135.35 cm). In conclusion, the plants sowed on October 15th with a maximum plant spacing of 25 cm had the highest values of the evaluated morphological, biochemical, and yield attributes of caraway.

    Opis:
    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.

    Opis:
    One of the most important problems in horticultural seed science and technology nowadays is looking for new methods to improve seed quality. Especially interesting are the ones, in which compounds of natural origin are used. One of such groups is ethereal oils from plants. The commercial seed samples of lettuce (Lactuca sativa L. ‘Dumka’) were soaked in 9 different treatments of 5% alcoholic solution of camphor tree (Cinnamomum camphora L.) ethereal oil and 9 different treatments of 5% alcoholic solution of patchouli plant (Pogostemon cablin Benth.) ethereal oil. Then the seeds were routinely tested for seed germination, the length of the received seedlings was also measured and the seeds health status was evaluated. The tested ethereal oils had no effect on the germination of lettuce seeds. However, soaking the seeds in the ethereal oils solutions did decrease the percentage of dead seeds in the tested samples. Soaking of the seeds in the ethereal oils solutions also increased the percentage of healthy ungerminated seeds. Treating the seeds with the concentrations of the ethereal oils solutions, although had no effect on their germination, still shortened the length of seedlings. Moreover, the used ethereal oils lowered the amount of identified Alternaria alternata and Cladosporium sphaerospermum fungi on the seeds.
    Jednym z najważniejszych problemów nasiennictwa ogrodniczego dziś jest poszukiwanie nowych metod poprawy jakości nasion. Szczególnie interesujące są te z nich, w których wykorzystuje się substancje naturalne. Jedną z takich grup są olejki eteryczne z roślin. Nasiona handlowe sałaty (Lactuca sativa L.) odmiany Dumka potraktowano na 9 różnych sposobów 5% alkoholowym roztworem olejku eterycznego z drzewa kamforowego (Cinnamomum camphora L.) i na 9 różnych sposobów 5% alkoholowym roztworem olejku eterycznego z paczuli (Pogostemon cablin Benth.). Następnie nasiona poddano rutynowej ocenie kiełkowania, zmierzono długość otrzymanych siewek i oceniono zdrowotność nasion. Badane olejki eteryczne nie wpłynęły na kiełkowanie nasion sałaty, natomiast zmniejszyły odsetek martwych nasion w badanych próbach. Moczenie nasion w badanych roztworach olejków zwiększyło także odsetek nasion zdrowych niekiełkujących. Traktowanie nasion roztworami olejków eterycznych o wyższych stężeniach, choć nie wpłynęło na ich kiełkowanie, to jednak skróciło długość otrzymanych z nich siewek. Ponadto stosowane olejki eteryczne obniżyły ilość oznaczonych na nasionach grzybów: Alternaria alternata i Cladosporium sphaerospermum.
