Various oils, fats and emulsifiers in the composition of preparations for soil enrichment or plant protection can have a significant effect on the germination capacity and energy of sprouting of pea seeds. Fat of black soldier fly (Hermetia illucens) larvae can be used as a pesticide carrier as well as for increasing seed resistance to contamination with fungi and insects during storage and sprouting. Therefore, the aim of the study was to determine an effect of insect fat in a form of an emulsion on sprouting of pea seeds of the variety “Rodnik” depending on a type of an emulsifier or stabilizer. It was found that the use of 0.3 weight% of xanthan gum as a stabilizer for fat emulsion of black soldier fly (Hermetia illucens) larvae significantly increased the number of germinated seeds and the energy of seed sprouting. The use of 1–5 weight% of Tween 20 as an emulsifier for fat of black soldier fly (Hermetia illucens) larvae led to inhibition of seed growth. Lecithin, sodium caseinate and microcellulose with addition of fat of black soldier fly (Hermetia illucens) larvae also decreased the germination capacity and sprouting of pea seeds (Pisum sativum L.).

Proximate And Mineral Composition

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

AbstractFeeding stem–leaf–pod explants with d-chiro-inositol and d-pinitol was used as a method to modify α-d-galactosides in developing pea (Pisum sativum) seeds. Four genotypes differing in the composition of raffinose, stachyose and verbascose (raffinose family oligosaccharides or RFOs) in seeds – high RFOs (cv. Tiny), low RFOs (SZD175) and low verbascose (cv. Hubal and cv. Wt 506) – were studied. Although seeds of all examined pea lines were able to take up both d-chiro-inositol and d-pinitol, only d-chiro-inositol was effectively converted into its galactosides: mainly fagopyritol B1 (O-α-d-galactopyranosyl-(1 → 2)-d-chiro-inositol) and fagopyritol B2 (O-α-d-galactopyranosyl-(1 → 6)-O-α-d-galactopyranosyl-(1 → 2)-d-chiro-inositol). In seeds of pea lines naturally containing low levels of verbascose (cv. Hubal) and low RFOs (SZD175), the enhanced accumulation of fagopyritols depressed the RFO level by c. 64 and 20%, respectively. Moreover, in both genotypes, about 25 and 30% of total galactose bound in α-d-galactosides occurred in fagopyritols. d-Pinitol present in the pea seeds was converted into monogalactosides, but their accumulation was several-fold lower than that of fagopyritols and did not significantly influence the accumulation of RFOs. Pea seeds with the composition of soluble carbohydrates modified by feeding with either of the cyclitols were able to complete germination.

Representative Samples

The goal of the trial was to reduce the content of antinutritional substances in pea (Pisum sativum L.) seeds in order to enhance its use in livestock nutrition. A variety of field pea (Pisum sativum L.) with a high content of antinutritional substances and favourable production traits (Gotik) was chosen. Native and heat-treated pea seeds were used to collect representative samples (n = 6) for analytical purposes. The technology (V-0 technology, Czech patent No. 285745) was further modified by adjusting the reactor temperature, the duration of exposure to that temperature, and the duration of ageing of the material treated in this way (V-I and V-II technologies). The methodology of treatment is based on exposing pea seeds to vapour, organic acids and selected oxides.The monitored parameters included antinutritional substances. As far as the antinutritional substances were concerned, the content of trypsin inhibitors in native pea seeds (P) was around 15.4 ± 0.5 TIU. After treatment with technologies V-0, V-I, and V-II its activity dropped by 83.8, 80.5 and 83.8%, respectively. The pre-treatment titre of lectins (P) was 717 ± 376. It dropped by 70.3, 35.7 and 73.2% after treatment with technologies V-0, V-I and V-II, respectively. The content of tannins measured by the amount of gallic acid in native pea seeds was 49.1 ± 2.7 mg per kg. It dropped by 41.4, 32.0 and 46.2% after the application of the above-mentioned technologies. The content of indigestible oligosaccharides causing flatulence was less affected by the treatments. The pre-treatment content of raffinose was 9.5 ± 0.5 g/kg. The drop associated with the treatment was 9.5, 6.3 and 10.5%, respectively. The pre-treatment content of stachyose was 21.4 ± 0.8 g/kg and after treatment with technologies V-0 and V-II it dropped by 7.0% and by 16.4%, respectively. The application of technology V-I did not result in a drop in the content of stachyose. The content of verbascose in native pea seeds was 16.1 g/kgand the treatment with technologies V-0; V-I and V-II resulted in a drop by 7.5, 5.6 and 20.5%, respectively. As for the detected phenolic acids, with the exception of caffeic acid, not a drop, but an increase in their content was recorded. Isoflavone oestrogens such as daidzein and genistein also recorded a small increase in their content. The results of the trial lead us to conclude that the above-described methods of pea seed treatment, especially the V-II variant, proved to be useful and can be recommended for practical use.

Apparently Healthy

A find of 2572 charred seeds of pea (Pisum sativum L.) was detected at the Late Bronze Age tell settlement Hissar near Leskovac, in Serbia, belonging to the Brnjica cultural group, 14-10 cent. BC. Two types of pea seeds were observed: apparently healthy seeds and seeds damaged by the activity of a weevil (Coleoptera, Bruchidae). At least two-fifths of all finds have apparently been infested most probably by pea weevil (Bruchus pisorum L.), one of the most important pea pests worldwide, especially in medium-moist and dry climates, such as Southern Europe and Australia. A large amount of infested pea seeds indicates a developed pea production on small plots, strongly indicating that cultivating this ancient pulse crop must have been well-rooted in field conditions. Previous DNA analyses of charred pea placed the ancient Hissar pea at an intermediate position between extantly cultivated pea (P. sativum L. subsp. sativum var. sativum) and a wild, winter hardy, 'tall' pea (P. sativum subsp. elatius (Steven ex M. Bieb.) Asch. et Graebn.). Based on an assumption of its late harvest time and combined with pea weevil life cycle stage in charred seeds, it was possible to estimate the season during which the seeds were carbonized, namely, the second half of July or the first days of August at the latest. Older, final weevil instars were predominant before seed carbonization. The pea infestation rate at Hissar is one of the highest noted among pulses in the Old World and the highest among peas, so far.

Objective. To evaluate the green pea (Pisum sativum L.) collection in order to identify carriers of r and rb mutations in it. Methods. Pea accessions were grown in the field, and seeds were produced under controlled pollination. The starch granule shape was determined in micrographs taken with a computer digital microscopic camera DMC-300 through a Biolam-15 microscope (object lens × 40). The starch content was determined polarimetrically by the Evers method and the amylase content colorimetrically — by the BO Juliano method. The data were statistically processed using analysis of variance. Results. The effect of r and rb mutations on the starch content and fractional composition in pea seeds was confirmed. In smooth-seed accessions the average starch content was 39,9 %, and the amylose content in starch was 45,9 %, while in r mutation carriers these contents were 31 ,2 % and 67,6 %, respectively, and in rb mutation carriers — 26,9 % and 28,2 %, respectively. An accession with marrowfat seeds, roundish starch granules and a low content of amylose in starch was identified. It was established that this accession was a carrier of a recessive mutation that is not allelic to r mutation and coincides with rb mutation by the effect type. Conclusions. A new genetic source of starchmodifying monogenic rb mutation of pea was identified. It was involved hybridization with sources of r mutation to expand the genetic basis of pea cultivar breeding.Keywords: peas, Pisum sativum, genetic diversity, r, rb, seed phenotype, starch grain shape, starch content, amylose content.
