Water deficit effects on caraway (Carum carvi L.) growth, essential oil and fatty acid composition

Evaluation of caraway essential oil from different production areas of Serbia

“…The assumption is that the lack of rainfall in the region of Banat caused a statistical increase in the essential oil content in caraway fruits. Laribi et al (2009) the water deficit increased the essential oil yield in caraway seed, as confirmed by our research.…”

“…Embong et al (1997) postulated that carvone content is increased by dry and sunny weather; either by the stimulation of photosynthesis which would in turn favour formation of carvone to formation limonene, or increased volatilization of the more volatile limonene leading thus to an altered ratio. However, water deficit can change plant behaviour regarding the biosynthesis of bioactive compounds (Laribi et al 2009). Water deficit induced an increase in the limonene proportion and decrease in carvone proportion, but did not affect the chemotype of caraway essential oils.…”

Irrigation Management for Higher Productivity in Seed Spices-A Review

“…Thus, water deficit induced a significant reduction in growth parameters and fatty acid content, and an increase in the essential oil compounds at medium water stress (Laribi et al, 2009). Total fatty acids content of caraway seeds decreases significantly by about 35.17 and 56.59 percent under medium water deficit and severe water deficit, respectively, in comparison to the seeds of no moisture deficit.…”

“…It has been reported that water deficit is a primary factor in increasing oil percentage of medicinal plants and increasing irrigation times significantly decreased the cumin oil percentage. It is reported that water stress affects the crop growth and development, but influence positively on biosynthesis of secondary metabolites and enzyme activities in many medicinal plants (Ahmadian et al, 2011;Laribi et al, 2009;Rebey et al, 2012). Based on this irrigation methods prevailing in seed spices are surface irrigation, sub surface irrigation and micro irrigation.…”

Textural and Petrographic Characterization of the Soil of Amtiman (South-East Chad)

“…Likewise, they are stable clays with a swelling-shrinkage effect, and can thus be used in the foundations of dwellings (Parker et Rae, 19890;Maison, 2011). The difference in cation exchange capacity values of kaolinite and illite is small (Laribi et al, 2009). These results do not agree with those of Gourouza et al (2003), according to which the mixed clays of Niger consist of 34% montmorillonite, 24% kaolinite, 17% illite and 25% interstratified illite / smectite.…”
