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.).

The research deals with nitrogen doses and sowing densities in peas. The objective was to determine which nitrogen dose and planting density obtained the highest yield. The methodology is based on applied research; Therefore, the statistical model of the Completely Random Block Design was used, which consisted of 3 blocks and 6 treatments. The doses were applied at 17 days 1/2 N, 100% P2O5 and 100% K2O and 62 days after sowing 1/2 N, it was evaluated from sowing to harvest and the data were processed by analysis of variance of two factors and Duncan, took leaf samples for foliar analysis and determined the total amount of nitrogen used. It was determined that T5 stood out in stem length with 128.42 cm, commercial yield with 12.53 tn/ha, T4 in weight of pods with 620 g, number of pods per plant with 48, T6 in nitrogen concentration with 6.60 g/ 100 g of dry matter and T5 in the amount of nitrogen used with 154.3 kg/ha that obtained the highest yield. It is concluded that the higher dose of nitrogen and less distance that is T5 obtained higher performance exceeding by 24.52% in relation to T1.

O processo de germinação de sementes ocorre em sucessivas etapas e depende da qualidade fisiológica das sementes. Os cultivos de ervilha (Psidium sativa L.) em diversas regiões do Brasil vêm se destacando por ser uma alternativa economicamente viável de produção e comercialização. Assim, objetivou-se com este trabalho avaliar o potencial germinativo e os vigores de sementes de ervilhas provenientes de diferentes fornecedores. O experimento foi realizado no município de Ijuí, RS, entre os meses de abril a junho de 2018 e envolveu um esquema fatorial (3x4x20), com um total de 480 sementes. Foram analisados os teores de umidade das sementes, bem como, a percentagem de germinação das sementes, altura média e número médio de folhas das plântulas e vigor característico. Foi possível concluir que a semente intitulada por T3 é a que tem maior potencial de germinação, não diferindo estatisticamente das sementes T1 e T2, mas sendo a única a diferir da semente T4. Para as características, altura média de plântulas, número médio de folhas e vigor, a semente T3 apresentou diferenças significativas em relação às demais. A qualidade fisiológica das sementes, incluindo vigores e germinação é dependente dos fornecedores de sementes. Análises de germinação e vigor são extremamente necessárias para saber as potencialidades produtivas de culturas de interesse.

The IPD3/CYCLOPS transcription factor was shown to be involved in the regulation of nodule primordia development and subsequent stages of nodule differentiation. In contrast to early stages, the stages related to nodule differentiation remain less studied. Recently, we have shown that the accumulation of cytokinin at later stages may significantly impact nodule development. This conclusion was based on a comparative analysis of cytokinin localization between pea wild type and ipd3/cyclops mutants. However, the role of cytokinin at these later stages of nodulation is still far from understood. To determine a set of genes involved in the regulation of later stages of nodule development connected with infection progress, intracellular accommodation, as well as plant tissue and bacteroid differentiation, the RNA-seq analysis of pea mutant SGEFix--2 (sym33) nodules impaired in these processes compared to wild type SGE nodules was performed. To verify cytokinin’s influence on late nodule development stages, the comparative RNA-seq analysis of SGEFix--2 (sym33) mutant plants treated with cytokinin was also conducted. Findings suggest a significant role of cytokinin in the regulation of later stages of nodule development.

Garden pea (Pisum sativum L.) is a globally important legume crop. Like other legumes, it forms beneficial symbiotic interactions with the soil bacteria rhizobia, gaining the ability to fix atmospheric nitrogen. In pea nodules, the meristem is long-lasting and results in the formation of several histological zones that implicate a notable differentiation of infected host cells. However, the fine transcriptional changes that accompany differentiation are still unknown. In this study, using laser microdissection followed by RNA-seq analysis, we performed transcriptomic profiling in the early infection zone, late infection zone, and nitrogen fixation zone of 11-day-old nodules of pea wild-type line SGE. As a result, a list of functional groups of differentially expressed genes (DEGs) in different nodule histological zones and a list of genes with the most prominent expression changes during nodule development were obtained. Their analyses demonstrated that the highest amount of DEGs was associated with the nitrogen fixation zone. Among well-known genes controlling nodule development, we revealed genes that can be novel players throughout nodule formation. The characterized genes in pea were compared with those previously described in other legumes and their possible functions in nodule development are discussed.
