“…Makkar et al (1997) reported values of 19-29 and 43.9-59.0 g/100 g for protein and oil contents, respectively, in J. curcas kernel from different countries. The oil content of J. curcas seeds is comparable with the contents obtained for some conventional oilseeds: safflower (29.3%), sunflower (19.5%) and peanut (30.3%) (Gama et al 2010;Alencar 2011;Ullah and Bano 2011). This unconventional seed may be an alternative to obtain oil and protein for human and animal consumption.…”

The origin of Jatropha curcas L. is in Central America, probably Mexico, although it is also distributed in South America, Africa and Asia. In Mexico, it grows as nontoxic and toxic J. curcas genotypes. In this work, the protein quality including protein efficiency ratio (PER), net protein ratio (NPR) and true digestibility (TD) of nontoxic genotype defatted flour was assessed using Wistar rats. The probed diets contained flour (3), flour‐lysine, 1% (4), flour‐phytase, 500 FTU (5) and two control diets: nitrogen‐free (1) and casein (2). The rats were fed for 28 days. The PER (1.37, 1.77 and 1.61) and NPR (1.80, 2.29 and 2.12) obtained values for diets (3.4 and 5) were lower than those obtained for casein (2.07 and 2.46), respectively. No statistical differences were found in TD. PRACTICAL APPLICATIONS Jatropha curcas defatted flour may be used in the food industry for the development of diets for human and animal consumption. Besides achieving fortification of foods that are made from wheat, which has a low protein content, with the addition of Jatropha meal, these foods will improve the protein quality of many food products.

“…Cytokinins have been used for increasing yield and oil contents of oil seed crops (Rijavec and Dermastia, 2010). Ullah and Bano (2011) used kinetin at rate of 10 -5 M during safflower flowering (140 day after sowing) as foliar application. They found that kinetin was highly effective in increasing achen yield, 100-achen weight.…”

Safflower seed yield is generally lower than that of other oilseed crops. So for this reason, it is necessary to increase safflower yield. Information regarding the effect of growth regulators and its suitable concentration on growth and yield of safflower is very limited. Therefore, two field experiments were conducted at the Desert Experimental Station in Wadi El-Natroon, Fac. Agric., Cairo Univ., during 2012/2013 and 2013/2014 seasons. Three growth regulators i.e., Melagrow, gibberellic acid, cytokinin were applied at three different concentrations viz., 20, 40 and 60 ppm, as well as, the control treatment of distilled water. The results revealed that all safflower traits were significantly affected by the tested growth regulators, except seed index and seed-oil %. Foliar application of the growth promoter Melagrow gave higher values for all studied traits compare with GA3 and Cytokinin, except plant height and linoleic%. Increase concentration of growth regulators from 0 up to 60 ppm significantly increased petal yield plant-1 by 48.3% and 37.1%, seed yield fed-1 by 26.4% and 21.3%, as well as, oil yield fed-1 by 29.4% and 27.5% in the first and second seasons, respectively. Quality traits, in terms of carthamin%, carthamidin%, oleic%, and oleic/linoleic ratio were significantly increased by increasing levels of growth regulators in both seasons. The highest values of such traits were obtained at 60 ppm level. The interaction effect between growth regulators and concentration on number of capitula plant-1 , seed weight plant-1 , petal yield plant-1 , seed and oil yields fed-1 was significant in both seasons. Spraying Giza-1 cultivar with Melagrow at 40 or 60 ppm four times was recommended for improving yields and its quality.

“…Many studies have shown that changes in the siliques color may be an indicative of seed maturation, as observed in canola oil . Concurrently, changes occur in chemical composition, which is reported for oilseed species such as canola, sunflower and safflower (Ullah and Bano, 2011). After maturation and harvesting, the deterioration process begins and that can be faster or slower depending on storage conditions of the seeds.…”

-The oil radish siliques maturation occurs in a non-uniform way, which makes it difficult to define the ideal harvesting time in order to produce high quality seeds. In addition, the high lipid content of the seed may hamper its preservation. To evaluate the effect of the maturation stage at harvesting on the physiological quality and chemical composition of the oil radish seeds stored under different conditions, the siliques were harvested at three stages, according to three colors: green, beige and brown. Seeds from different siliques harvesting stages were stored at ambient conditions and in a cold chamber under dry conditions (10 °C and 46% RH) and evaluated as to their physiological and health quality and chemical composition before being stored and after 3, 6 and 9 months of storage. The siliques color is not the ideal indicator to define the oil radish seeds harvesting time due to the variation of the maturity and physiological quality of oil radish seeds within the siliques. The oil radish seeds storage in cold chamber preserves the physiological quality as assessed by the emergence test. There were no consistent changes in the centesimal composition of oil radish siliques harvested at different stages of maturation in relation to their color alteration.Index terms: Raphanus sativus, storage, maturation.Colheita, beneficiamento e controle de qualidade de sementes de nabo forrageiro RESUMO -A maturação das síliquas de nabo forrageiro ocorre de maneira desuniforme, o que dificulta a definição do momento ideal de colheita para produção de sementes de qualidade superior. Além disso, o alto conteúdo lipídico da semente pode dificultar sua conservação. Para avaliar o efeito do estádio de maturação na colheita sobre a qualidade fisiológica e a composição química de sementes de nabo forrageiro armazenadas sob diferentes condições, as síliquas foram colhidas em três estádios de maturação identificados pelas colorações, verde, bege e marrom. As sementes provenientes dos diferentes estádios de colheita das síliquas foram armazenadas em condições ambientais e câmara fria e seca (10 °C e 46% de UR) e avaliadas quanto à sua qualidade fisiológica, sanitária e composição química antes de armazenadas e aos 3, 6 e 9 meses de armazenamento. A cor das síliquas não é indicativo ideal para definição do momento de colheita das sementes de nabo forrageiro pela variação de maturidade e qualidade fisiológica das sementes dentro das síliquas. O armazenamento das sementes de nabo forrageiro em câmara fria preserva a qualidade fisiológica conforme avaliação do teste de emergência. Não foram observadas alterações consistentes na composição centesimal em síliquas de nabo forrageiro colhidas em diferentes estádios de maturação relacionados à sua alteração de cor.Termos para indexação: Raphanus sativus, armazenamento, maturação.
