Relationship Between Essential Oil Content, Fruit Yield and Yield Component in Foeniculum vulgare Mill.

Fennel (Foeniculum vulgare var. vulgare Mill.) is an perennial herb, it is cultivated for the essential oil in the fruits. The quality criteria are essential oil content, microbiological contamination and residua of pesticides. The important part of the cultivation technology is ununiform maturity of the fruits. The aim of this work was to find out the influence of the desiccants on quality and yield characteristics of fennel fruits produced in field conditions in the first years of growing. Three preparations were applied: glufosinate-NH4, 150 g.l–1 (2 l.ha–1), diquat dibromide, 200 g.l–1 (3 l.ha–1) and glyphosate-IPA, 480 g.l–1 (3 l.ha–1) in three repetitions. The non treated control variant was also repetited three times. The samples were analysed for quantitative and qualitative parameters: the fruit yield (t.ha–1), the essential oil content (%, V/m), the essential oil yield (kg.ha–1), the essential oil composition and the residua content.

Main Component

The purpose of this study was to analyze the Foeniculum vulgare Mill. collection by the content and component composition of essential oil. The study was carried out in 2017-2019. The collection is located in the experimental site of the Research Institute of Agriculture of Crimea, located in the Crimea Foothill (Krymskaya Roza village) in accordance with the developed methods. The component composition of F. vulgare essential oil was determined by the method of gas chromatography on the “Crystal 5000.2”. It was found that the essential oil content in mature F. vulgare fruits amounted to the average of 5,88± 0.10%, which was higher than in the green plants’ material - 2,36± 0.06%. The main component of the essential oil is anethole. The anethole content in essential oil from fruits was higher than from the green plants’ material: 64.9-84.3% and 33.5-74.6%, respectively. 66.0% of the analyzed samples corresponded to ISO 17412:2007 requirements. Essential oil from the green plants’ material contained more α-phellandrene compared to essential oil from fruits: 1.5-19.9% and 0.1-0.4%, respectively. According to the research results, 9 promising samples with a high content of essential oil in fruits - from 6,52 ± 0.88 to 8,10± 0.91% were distinguished.
