Not AvailableOil content analysis in oilseed crops requires methods that are non-destructive, accurate, fast, eco-friendly (without the use of solvent), inexpensive in terms of consumables, and easy to use. Pulsed low-resolution nuclear magnetic resonance (NMR) satisfies all these conditions. The objective of the present study was to develop an oil measurement method for seeds using NMR spectrometry. A bench-top pulsed NMR analyser was calibrated with respect to temperature. Six genotypes each of sunflower, safflower and castor were used for the analysis. Changes in sample conditioning temperature can lead to significant changes in the calibration graph. Based on the statistical parameters (correlation coefficient, variance and standard deviation) obtained, the best calibration was found for sunflower and safflower at 40C and castor at 44C among the temperature ranges tested.Not Availabl

Not AvailableFive oilseed based cropping systems fallow-safflower; pearl millet-chickpea + safflower (3:1); fallow-sunflower; soybean-sunflower and soybean + pigeonpea (4:2) which are popular in Vertisols were evaluated in four land configuration practices in broad bed and furrow system. The amount of rainfall received during cropping season (June-March) was 1009 mm. Crops did not suffer from moisture stress. Land configuration practices did not differ statistically in influencing the cropping systems productivity. Among the different oilseed based cropping systems, soybean + pigeonpea (4:2) recorded significantly the highest system productivity (4625 kg/ha). The system productivity of other four were in the order of double cropping of soybean-sunflower (3175 kg/ha) > millet-chickpea+safflower (1513 kg/ha) > fallow-sunflower (1488 kg/ha) > fallow-safflower (1200 kg/ha).Not Availabl

Not AvailableSafflower (Carthamus tinctorius L.) is an important oilseed crop, its oil demand is increasing world over because of its potential for multi-purpose uses. Oleic content in safflower oil is generally around 17-20% making it unsuitable for deep frying (Gecgel et al. 2007). High oleic safflower oil is stable at high temperatures and makes it superior for frying. High oleic oil is also suitable as a biodiesel fuel additive (Bergman and Flynn, 2001). The high oleic safflower line, Ole-9-P2-P1-P22, having 81% oleic content was developed from a cross, EC523367-9 x EC548816-14, through back-crossing followed by sib-crossing and simultaneous selection for high oleic and high oil content at the Directorate of Oilseeds Research, Hyderabad, India (Praduman and Anjani, 2012). The parent, EC-523367-9 is a high oleic selection and the parent, EC-548816-14 is a lenoleic selection possessing high seed weight.Ole-9-P2-P1-P22 possesses high oil content (34%). It is spiny in nature with profuse branching habit, serrate obvate upper leaves and green stem. It matures in 70-75 days and matures in 120 to 125 days after planting. It also exhibited resistance to wilt (Fusarium oxysporum f.sp carthami) in wilt sick plot over three years at the Directorate of Oilseeds Research, Hyderabad.Not Availabl

Not AvailableCastor (Ricinus communis L.) is one of the ancient non-edible, multi-purpose, drought tolerant oilseed crop. It has a long history of more than 6000 years. Castor seeds were an important item of commerce in ancient Egypt. The castor seed is the source of numerous economically important products and is one of the world’s most important vegetable oils for industrial usage. Dioscorides named castor as Kroten or Kiki in Greek, and the genus Ricinus is derived from the latin term meaning ‘dog tick’ because of the resemblance of its seed as that of the common pest of dogs which Linnaeus retained. The plant’s common name was apparently coined by English traders who confused the oil with that from Vitex agnus-castus, known to the Spanish and Portuges in Jamaica as agno-casto.Not Availabl

Not AvailablePlants are exposed to various environmental stresses throughout their life cycle. Plants possess physical barriers, such as the cuticle, the cell wall and a number of biological and molecular mechanisms to counteract the effect of these stresses, which also includes the synthesis of ROS, namely the oxidative burst. ROS can react with proteins, DNA, and membrane lipids to reduce photosynthesis, increase electrolyte leakage, and accelerate senescence and cell death. These are under strict control through an antioxidative system comprising various enzymes and low molecular weight components. ROS are not only toxic by-products of aerobic metabolism, but are also signalling molecules involved in several developmental processes. Here, the divergent sources of ROS and antioxidative system that is present in plant cells are discussed and also reviewed the role of ROS in the cell signalling.Not Availabl
