Some natural products are known to kill fungi and destroy toxins and toxin-producing agents. Objectives: The purpose of this study is to provide experimental data on the antifungal activity of cumin oils and their components that could be considered suitable for application in foods and drugs. Materials and Methods: The essential oil (EO) of Cuminum cyminum L. collected from Alborz Mountain, Iran, was obtained by hydro-distillation. The oil was analyzed by gas chromatography (GC) and chromatography/mass spectrophotometry (GC/MS). The antifungal activity of the oil was studied with regard to the inhibition of the growth of Aspergillus flavus PICC-AF39 , Aspergillus flavus PICC-AF24, Aspergillus parasiticus NRRL-2999 and Aspergillus niger. The minimal inhibitory (MIC) and minimal fungicidal (MFC) concentrations of the oil were determined. Results: α-Pinene (29.2%), limonene (21.7%), 1,8-cineole (18.1%), linalool (10.5%), linalyl acetate (4.8%), and α-terpineole (3.17%) were the major components of the essential oil from C. cyminum L., and the oil showed a strong inhibitory effect on fungal growth. Conclusions: Essential oils could be safely used as preservatives in pharmaceuticals as well as health and food products to protect them against toxigenic fungal infections.

Quadratic and linear models were used for simulating leaf area expansion. Functional models were used using leaf area at 10 days interval from 10 to 120 DAS, under four weed management practices viz., (i) Atrazine, 0.75 kg ai/ha (eliminating competition of grasses and broad leaf weeds), (ii) 2, 4-D EE 0.8 kg ai/ha (eliminating competition from broad leaf weeds), (iii) Hand weeding at 20 and 40 DAS (eliminating all weed types competition) and (iv) Unweeded control (offering competition of all weed types). Fourth degree polynomial showed prediction of 88 to 98% in simulating course of leaf area expansion per unit leaf number in maize, while quadratic model showed prediction of 88 to 96% and linear model gave prediction of 74 to 88%. Differentiating quadratic and the linear functional models indicated that relative rate of leaf area expansion (RRLAE) (cm 2 /plant/day) was improved by 455.06 to 491 in hand-weeding or Atrazine application due to elimination of weed competition over unweeded control. Further, models worthiness by using linear and quadratic models in terms of relative rate of leaf area expansion in maize was higher with pre-emergence use of Atrazine or Oxyfluorfen at 3 DAS and was compared similar to hand weeding at (20 and 40 DAS).

This experiment was conducted in the greenhouse of the laboratory of tropical horticultural science, department of International agricultural development, Tokyo University of Agriculture. The design was a factorial CRD (completely randomized design) with five sodium chloride (0 mM, 50 mM, 100 mM, 150 mM, and 200 mM) treatments and four primings (0 MPa, 0.4 MPa, 0.8 MPa, and 1.2 MPa) treatments. Micro-Tom seeds were soaked in polyethylene glycol (PEG6000). Salinity was applied through irrigation water when the first flower bloomed. Reproductive-related parameters such as the number of flowers per plant, pollen viability, pollen germination, pollen tube length, number of fruits per plant, fruits size and yield per plant were measured. It was observed that salinity affected the tomato plants severely during the flowering stage, and many flowers did not bear fru...

Empirical models simulated the crop growth (dry matter production) of maize by 98% indicating that competition of weed types did not alter the pattern of growth of maize, but cumulatively affected the total dry matter at harvest, where as, the linear function predicted the crop growth by 92 to 94%. Differentiating quadratic and linear functions indicated that dry matter production efficiency (DMPE) were improved by 34 to 46% in hand weeding or atrazine treatments due to elimination of weed competition over unweeded control. Competition of grassy weeds (in 2,4-D EE treatment) lowered the DMPE by 24% over atrazine treatment with less weed competition, while competition from broad leaf weeds and sedge lowered the DM...
