A Novel Continuous Phase‐Transition Extraction Effectively Improves the Yield and Quality of Finger Citron Essential Oil Extract

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.

Different Doses

Caraway has very low competitive ability against most of weed species. Therefore, it is important to choose a suitable herbicide control, especially at biennial caraway. The experiments with the herbicides applied in caraway were found in pure growth, with variety Kepron (with standard length of vegetative period). The aim of the trials was to find out the differences at achenes yiled and essential oil content after the treatment by the various herbicides, applied preemergently. Also, the selective activity of individual herbicides was tested, including the different doses. The herbicides used in the experiments had enough level of selektivity on the plants of caraway. They had a positive effect on the yiled comparing to non-treated control variant in all observed years. There was no statistically significant difference in essential oil kontent between the treated variants and non-treated control. On the basis of these results, the most suitable herbicide was chosen for the „minor“ registration for caraway.

Physical And Chemical

A field experiment was conducted from 1989 to 1991 on a Fox loamy sand soil to study the effects of harvest date on selected agronomic, physical and chemical characteristics of peppermint (Mentha piperita L.). Plant biomass and essential oil yields increased throughout the season to a maximum in very late August to early September. Menthol, neomenthol, and menthyl acetate concentrations increased in the essential oil with plant development. The amount of menthone and isomenthone was highest in immature plants. The concentrations of menthofuran and pulegone in the essential oil corresponded to the amount of flower bloom in the peppermint. Changes during the season in the concentrations of piperitone, terpinene-4-ol, α-terpineol, 1,8-cineole, limonene, γ-terpinene, terpinolene, α-terpinene, α-pinene, β-pinene, 3-octanol, β-myrcene, Linalool, sabinene, caryophyllene and Germacrene-D were typically quite small. In general, these preliminary results indicate that peppermint can be grown successfully on the coarse-textured soils of Ontario.

Tuning Parameters

We present further methods to investigate in how far atmospheric precipitation can be described as a continuous phase transition. Previous work has shown a scale-free range in the rainfall event size distribution and a suggestive power-law pickup in the rain rate above a critical level of instability. Here we examine an additional technique for estimating critical parameters, we investigate the rain rate pickup for an example of an extreme event, namely satellite observations of Hurricane Katrina, and develop an analysis of fluctuations in the rain rate to estimate uncertainties in the tuning parameters relevant for the transition.
