Oil content and lipid composition of safflower (Carthamus tinctorius) irrigated with saline water under greenhouse and field conditions

Abstract

An intensive process of land deterioration of some regions in Uzbekistan including the Aral Sea basin has led to a significant increase in soil salinity levels and consequently to a considerable reduction of total fertile soil area, as these lands are of little use for plant growth. The area is estimated to be more than 1.4 million ha of seabed. As a result, there was an immediate need to cultivate new crops capable of stopping the movement of sands and the enlargement of saline soils. Safflower (Carthamus tinctorius) is considered to be a moderately salt-tolerant crop and, as such, one of a few crops well suited to the cropping systems of salt-affected soils. It is used in Uzbekistan as a reserve crop when the culture of the main crop fails. In spite of the great economic importance of this oil, there is almost no available information in the literature on the effect of salinity on oil quality and its chemical ingredients. The purpose of the present study was to determine, in greenhouse and field experiments, how irrigation with saline water would influence content of oil, lipids and other lipophylic components in safflower. We found that irrigation of safflower with moderate concentrations of saline water seems feasible, as far as oil and lipid composition is concerned. Consequently, safflower might be a potential crop for lands of little use for plant growth in Uzbekistan or other similar sites in the world.

Digital Phenotyping to Delineate Salinity Response in Safflower Genotypes

“…Safflower is a moderately salt (Francois et al, 1964;Maas, 1993;Kotuby-Amancher et al, 2000;Golkar, 2011) and drought tolerant (Istanbulluoglu, 2009;Hussain et al, 2016;La Bella et al, 2019) oilseed crop suitable for growing in a range of environments. Previous research has focussed on the effects of saline irrigation water, under field conditions, on safflower growth, morphology, and yield (Francois et al, 1964;Janardhan et al, 1986;Yeilaghi et al, 2015;Hussain and Al-Dakheel, 2018), as well as oil characteristics (Yuldasheva et al, 2011;Yeilaghi et al, 2012). Studies on glasshouse grown safflower have sought to understand the effects of Na + on vital traits including salt tolerance inheritance (Golkar, 2011), stress signaling pathways (Severino et al, 2014;Shaki et al, 2019), and oil composition (Yuldasheva et al, 2011;Harrathi et al, 2013).…”

Growth, Development and Yield of Crambe Abyssinica Under Saline Irrigation in the Greenhouse

“…Crambe abyssinica is a potential oilseed crop for semiarid and arid ecosystems where saline soils and saline irrigation water is common. This species is mainly used for industrial oil production and ornamental purposes (Carlson et al 1985, Yuldasheva et al 2011a and might be also used as a protein feed supplement in livestock feeds (Castaneda 1983, Perry et al 1983. Water stress conditions induced by polyethylene glycol solutions significantly reduced seed germination and vigour in Crambe (Teixeira et al 2011).…”

Evaluating the Contribution of Ionic and Agronomic Components toward Salinity Tolerance in Safflower

“…S alinity is one of the most important environmental factors that limits crop yield in arid and semiarid regions of the world. Moreover, in these regions, water availability is the main factor determining crop production, and the non‐conventional water resources such as saline water and treated sewage effluent are becoming important sources of water supply (Yuldasheva et al, 2011). Saline soil in Iran is about 23.8 million hectares of total land area (Ghassemi et al, 1995).…”
