Brokkoli Tohumlarına Uygulanan Bazı Organik Asit ve Bitkisel Kökenli Materyallerin Çimlenme, Çıkış ve Fide Kalitesine Etkisi

The research was carried out to investigate the effect of plant materials which are used as an alternative to synthetic chemicals in organic agriculture (thyme, mint, basil and garlic oil, hot pepper, and neem tree seed extract) and some organic acids (salicylic and jasmonic acid) on the germination, emergence, and seedling traits in broccoli (Brassica oleracea var. italica) cv. Jade. The seeds of broccoli treated with these materials were subjected to germination and emergence tests at 20±1°C and 60±5% RH in autumn period. After that, all seeds (including untreated) were kept at 5±1°C and again evaluated for germination, emergence, and seedling traits in spring period. In spring period, the seeds treated with neem seed extract gave highest germination percentage (91.75%). Also, they germinated in shortest time (3.80 days). The lowest germination/emergence percentage and highest mean germination/emergence time was obtained from the seeds treated with thyme oil in both periods. The seeds treated with basil oil had the higher infected seedlings than others. There were no significant differences among treatments in term of seedling traits (except leaf number).

In recent years, green nanotechnology-based approaches using plant materials have been accepted as an environmentally friendly and cost-effective approach with various biomedical applications. In the current study, AgNPs were synthesized using the seed extract of the Eugenia uniflora L. (E.uniflora). Characterization was done using UV-Visible spectroscopy, X-ray diffraction (XRD), scanning electronic microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses. The formation of AgNPs has confirmed through UV-Visible spectroscopy (at 466 nm) by the change of color owing to surface Plasmon resonance. Based on the XRD pattern, the crystalline property of AgNPs was established. The functional group existing in seed of E.uniflora extract accountable for the reduction of Ag+ ion and the stabilization of AgNPs was investigated. The morphological structures and elemental composition was determined by SEM and EDX analysis. With the growing application of AgNPs in biomedical perspectives, the biosynthesized AgNPs were evaluated for their antibacterial and along with their antidiabetic potential. The results showed that AgNPs are extremely effective with potent antidiabetic potential at a very low concentration. It also exhibited potential antibacterial activity against the three tested human pathogenic bacteria. Overall, the results highlight the effectiveness and potential applications of AgNPs in biomedical fields such as in the treatment of acute illnesses as well as in drug formulation for treating various diseases such as cancer and diabetes. It could be concluded that E. uniflora seed extract AgNPs can be used efficiently for in vitro evaluation of their antibacterial and antidiabetic effects with potent biomedical applications.

ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours after application, the number of dead larvae per plant was counted. In the second step, pupal mortality was recorded. The total mortality was also calculated considering the number of larvae and the number of emerged adults. We verified that, increasing the concentration of aqueous neem seed extract, an increase in the larval and pupal mortality of the leafminer in melon crop was noticed. The concentration 10 g/100 mL presented the best results, resulting in 36.4% of larval mortality, 96.5% of pupal mortality and 96.8% of total mortality.

The efficacy of the Senegal prickly-ash Zanthoxylum zanthoxyloides (Lam.) roots and the African locust bean tree Parkia biglobosa (Jacq.) pod back was study for their efficacy in the control of okra pest, Podagrica spp. The study was carried out in the laboratory and on the field in the farming season of 2018. Z. zanthoxyloides roots were obtained from Jima-Doko forest and P. biglibosa fruit back from Takunpara. Both plant materials were air-dried under shade for 120 hours. Both plant parts were pounded separately in wooden mortar with the aid of wooden pestle until the materials turns to fine particles. Determined weight of 100, 150, 200, 250, and 300 grams were taken for each plant materials and soaked in water for 24 hours and stirred at intervals of an hour. The mixture were then sieved with a muslin cloth and filtered with Whatman filter paper to eliminate all finest particles of varying sizes. These concentrations were applied individually on 10 adults of Podagrica spp. in the laboratory. It was observed that the concentration of 200 – 300g performed better for both plant materials in the control of okra flea beetle. These resulted to the death of above 50% of the insect within 2 hours. These significant laboratory trials were then formulated and taken to the field. Both plant materials acted as anti-feedants and repellants against Podagrica spp. It was also revealed that Z. zanthoxyloides performed significantly (p<0.05) better than the P. biglibosa. Furthermore, short interval applications (<or=3days) of these plant materials could be a good replacement for synthetic chemicals, hence bio-pesticides that could be adopted for organic agriculture.

Neem Seed Extract

Abstract A neem seed extract was applied to black spruce trees at two stages of reproductive development to control insect damage to the seed cones. Applied after pollination, neem had no effect on damage by the spruce cone maggot but did provide some protection against defoliation by the spruce budworm. Neem had no effect on the numbers of spruce budworm larvae for the first 9 days of the experiment, but after 23 days, populations declined on trees with two of three neem treatments compared to control trees. Neem reduced cone grazing damage by lepidopteran larvae when applied during the flowering stage. However, increased female flower abortion also resulted. The application of neem seed extract for controlling spruce budworm damage appears promising, but more information is needed on earlier applications in the field to determine if this product could be used operationally without causing substantial flower abortion.

Emergence Percentage

Large achenes of sunflower (Helianthus annuus) exhibited a slightly higher germination percentage and greater mean hypocotyl length than small achenes, resulting in a higher field emergence percentage at sowing depths exceeding 6 cm. Size of achenes sown had no effect on achene yield, provided plant populations from large and small achenes were equal. Plants grown from small achenes produced achenes of higher kernel percentage in both seasons, resulting in higher protein percentage in one season and higher oil percentage in the other. Performance of ungraded achenes was equal to that of graded achenes of the same mean size. Deep sowing reduced emergence percentage considerably, especially when small achenes were sown, but the effect of deep sowing on growth and yield was confounded with effects of reduced plant density (because of reduced emergence) and effects of delayed emergence causing slightly later timing of growth and development processes in relation to environmental factors.
