Potential of <i>Opuntia</i> seed oil for livelihood improvement in semi-arid Madagascar

Safflower seeds provide an oil rich in mono and polyunsaturated fatty acids. Its adaptation to drought and high temperatures makes it an alternative for the development of oleaginous crops in semi-arid areas. This study examines the oil content and the chemical composition of seed oil from three safflower accessions (Gila, Halab, Touggourt) cultivated over three years (2015, 2016, and 2017) in a semi-arid area in Tiaret (West of Algeria). Under these semi-arid conditions, characterized by low rainfall and high temperatures, seed oil content remained relatively high and was composed mainly of unsaturated fatty acids, with their ratio to saturated fatty acids reaching an average value of 9. Seed oil content varies between 22.8% and 28.4% among the genotypes and throughout the three years. The extracted oil consists essentially of unsaturated fatty acids, linoleic and oleic acids, poly and monounsaturated, respectively. Their contents over the three years vary between 75% and 79.3% for linoleic acid and between 10.2% and 14.7% for oleic acid. The saturated fatty acids content of the oil reached a maximum value of 9%. They consist mainly of palmitic acid, of which the average genotypic content varies between 6.6% and 7.15% depending on all grown years. The results obtained may assist in better understanding the response of cultivars under rainfed conditions and could be helpful for breeders with regards to introduction into selection programs.

Interest in oilseed crops for agro-industrial research and development projects has increased in the Mediterranean area, in recent years. Safflower (Carthamus tinctorius L.) is of potential interest for agriculture mainly due to fatty acid content variability in the seed oil. The aim of this study was to assess the agronomic performance of 16 new safflower accessions together with safflower variety Montola 2000, used as a reference, in a semi-arid environment. Research was carried out in Sicily (Italy) from 2013–2014. Hierarchical cluster analysis carried out on the fatty acid composition of safflower accessions resulted in their division into four main groups. Linoleic, oleic and palmitic acids were the main fatty acids present in the accessions. Seed yield was 1.11 t ha−1 on average and seed oil content was found to be approximately 35.01% of dry matter on average. Positive and significant relationships between seed/oil yield and other tested traits were found. The carbon, hydrogen and nitrogen content as a percentage of dry matter varied greatly both for the above- and belowground plant parts on average. This study confirms the interest of safflower for both food and non-food applications, offering interesting prospects in semi-arid regions.

AbstractFive Euphorbiaceae species (Jatropha macrocarpa, J. hieronymi, J. excisa, Cnidoscolus tubulosus and Manihot guaranitica) were analysed for seed oil content and fatty acid profiles in order to evaluate their potential as sources of biodiesel. The five species are perennial shrubs adapted to arid and semi-arid environments of north-western Argentina. The seed oil content for all species ranged from 27.9 to 38.7% by dry weight. Fatty acid composition consisted mainly of linolenic, myristic, palmitic, stearic, arachidic, oleic and linoleic acids, with linoleic and oleic acid being the most abundant. Among the five species analysed, J. macrocarpa has the best potential to be used as a biodiesel source. The average total seed oil content (35.8%) and a high value of oleic acid (27.3%) together with the lowest values of linoleic acid (55.8%) make this species a promising crop as a source of biodiesel in arid and semi-arid regions.

Number Of Seeds

The research experiments conducted on the role of salicylic acid (SA) sprayed in three concentrations viz., 0.5 mM, 1.0 mM and 3.0 mM on the yield in terms of buds/plant, flowers/plant, number of bolls/plant, boll weight, fibre length, number of seeds/plant, 100 seed weight and cotton seed oil contents of two varieties of cotton (Gossypium herbaceum L.) viz., Bt- cotton and non-Bt plants grown in the semi-arid tropics of Nizamabad was studied. Nizamabad district soil is known for its salinity and the black soil which is largely responsible for the drought and saline stresses which hampers plant growth and metabolism. Application of three concentrations of SA stimulated the yield of both Bt-cotton and non-Bt cotton varieties. The Bt-cotton variety showed better performance over non-Bt varieties. SA at 3.0 mM conc. was found most effective in increasing the yield of both cotton varieties of over 1.0mM SA, 0.5mM SA applications as well as untreated controls. The enhancement of yield in terms of buds/plant, flowers/plant, number of bolls/plant, boll weight, fibre length, number of seeds/plant, 100 seed weight and cotton seed oil contents in both cotton varieties is an indicator that SA mitigated the negative effect of the semi-arid conditions of the soils in Nizamabad district.
