Analysis of interspecies physicochemical variation of grain legume seeds

Abstract

A b s t r a c t. The paper presents an attempt to assess the reaction of seeds to mechanical loads taking into account their geometry expressed as seed thickness and 1000 seed weight. The initial material comprised 33 genotypes of grain legume plants and included cultivars registered in the country and breeding lines that are subject to pre-registration trials. The analysis of variance revealed significant diversity of the cultivars and lines of the species studied in terms of each of the analysed trait. The highest weight of 1000 seeds were obtained for white lupine seeds and peas, the lowest for andean lupine seeds. The maximum deformation and energy were obtained for white lupine seeds, the lowest for pea seeds, the maximum force and module the lowest values were determined for narrow-leafed lupine and pea. The highest values of protein were obtained for andean and yellow lupine, a fat content for andean and white lupine. The fatty acid profile as much as 70% or more were linoleic and oleic acids. Against the background of all the species are distinguished by white lupine seeds with a high content of oleic acid and the lowest of linoleic acid, for yellow lupine were obtained the inverse ratio of the two acids.

Estimation of the physicochemical variation of chickpea seeds (Cicer arietinum L.)

“…What appears characteristic are the very low values of the maximum load for small-seeded Desi accessions Nos 44 and 47, originating in Ethiopia and India. A similar average value of this parameter, at the level of 240 N, was obtained for lentil seeds, while the value of 276 N was obtained for grass pea seeds, 440 and 404 N for narrow-leafed and yellow lupine, respectively, and 932 N for the particularly resistant seeds of white lupine (Rybiński et al, 2014). The same accession as for the maximum load (No.…”

Variability of fat content and fatty acids profiles in seeds of a Polish white lupin (Lupinus albus L.) collection

“…Another literature data for linolenic acid are comparable to ours [8.88% in Mierlita (2015), 9.2% in Uzun et al (2007), 9.68% in Bhardwaj (2002) and 10.2% in Oomah and Bushuk (1984)]. The content of linolenic acid in seeds of narrow-leafed lupin, yellow lupin and Andean lupin was lower: 6.2, 4.2 and 2.6%, respectively (Petterson, 1998;Cowling and Tarr 2004) and 4.9, 8.13 and 2.86% (Rybiński et al 2014).…”

“…1) the average percentage of palmitic acid was in the range from 6.09% for CO accessions to 6.68% for accessions of XD with the broadest variation from 4.5 to 9.0% for LR accessions. Average content of palmitic acid (6.37%) is similar to 6.21, 6.79, 7.2 and 7.6% reported for white lupin by Rybiński et al (2014), Mierlita (2015), Oomah and Bushuk (1984) and Uzun et al (2007), respectively, but markedly lower as compared to 11.6 and 15.2-19.8% noticed by Erbas et al (2005) and Boschin et al (2008), respectively. No significant differences (7.8 and 7.1%) were found between sweet and bitter white lupin (Yorgancilar and Bilgicli 2014).…”

“…It is particularly true for Andean lupin with oil content on the level 16-20% (Ś więcicki et al 2015). Lower content have seeds of white lupin (9.76-12.1%) but higher as compared to narrow-leafed and yellow lupin -6.5 and 5.1% as well as to field pea and grass pea -1.6 and 1.1%, respectively (Rybiński et al 2014). Oil is present particularly in cotyledons, 95-98% of total content (Smulikowska et al 1995).…”

“…yellow lupin and narrow-leafed lupin, have lower x-3/x-6 ratio, due to a much higher linoleic acid content (Boschin et al 2008). According to data given by Rybiński et al (2014) seeds of yellow lupin, narrow-leafed lupin and Andean lupin contain high amount of linoleic acid (51.9, 40.5 and 34.5%, respectively) as compared to white lupin (15.6), what in consequence influences the unfavorable low value of x-3/x-6 fatty acid ratio (0.16, 0.12 and 0.10, respectively). Similar low values for vegetable oils, such as olive oil (0.13), soybean oil (0.15) and walnut oil (0.20) noticed Belitz and Grosch (1999).…”
