Three lots were used for the cultivars Tabarana, Tucunaré and Monsoy 8866. The analyzes were germination, seedling emergence, tetrazolium test, oil content, protein and free fatty acids. The lot 3 of Tabarana cultivar presented higher germination compared to the others. By the tetrazolium test, the seed viability was similar between lots and cultivars. The seedling emergence was higher in Tabarana cultivar and also from seeds of lot 3. The contents of protein, oil free fatty acids in soybean seeds were variable between lots and reflected in the average difference between cultivars. The protein content was higher in Tabarana cultivar and oil content showed higher value in cultivar Monsoy 8866. The free fatty acids was lower in seeds of Tucunaré cultivar. The chemical composition varies among seed cultivars and lots, maintaining relationship the quality of soybean seeds. / O presente trabalho teve por objetivo estabelecer relação entre a variabilidade da composição química e a qualidade fisiológica de sementes de soja. Foram empregados três lotes de sementes de soja, cultivares Tabarana, Tucunaré e Monsoy 8866. Foram realizados os testes de germinação e de emergência de plântulas e de tetrazólio e determinações dos teores de óleo, proteína e ácidos graxos livres. O lote 3 da cultivar Tabarana apresentou maior germinação comparativamente aos demais. Pelo teste de tetrazólio, a viabilidade de sementes foi similar entre lotes e cultivares. A maior emergência de plântulas verificou-se no lote 3 da cultivar Tabarana. Os teores de óleo, proteína e ácidos graxos livres em sementes de soja foram variáveis entre lotes e refletiram em diferença média entre cultivares. O teor de proteína foi maior em sementes da cultivar Tabarana e o teor de óleo apresentou maior valor nas sementes da cultivar Monsoy 8866. O nível de ácidos graxos livres foi inferior na cultivar Tucunaré. A composição química de sementes é variável entre cultivares e lotes e apresenta relação com a qualidade fisiológica de sementes de soja.

<p>Izvod<br />IZ<br />Pet hibrida suncokreta (Sremac, Oliva, Cepko, NS-H-111 i Sumo 2 OR) gajena su tokom<br />vegetacionih sezona 2010. i 2011. godine na oglednom polju Instituta za ratarstvo i<br />povrtarstvo, Novi Sad, na Rimskim &scaron;ančevima i na oglednom polju Poljoprivredne stručne<br />službe Zrenjanin. Laboratorijski deo ogleda izveden je u Laboratoriji za ispitivanje semena<br />Instituta za ratarstvo i povrtarstvo iz Novog Sada i Biohemijskoj laboratoriji<br />Poljoprivrednog fakulteta u Novom Sadu. Cilj istraživanja je bio da se utvrdi da li semenski<br />materijal, poreklom sa istog lokaliteta i iste parcele, u procesu dorade semena tj. odvajanja<br />semena po frakcijama menja kvalitet, kao i da li ovakav način dorade semenskog materijala<br />utiče na prinos i komponente prinosa semena, kao i na sadržaj i prinos ulja odabranih<br />hibrida suncokreta. Takođe, cilj je bio i da se utvrdi da li nedostatak primarnog korena kod<br />ponika suncokreta dovodi do statistički značajnog smanjenja prinosa semena i ulja, kao i<br />kakav uticaj ima na komponente prinosa suncokreta. Analizirane su sledeće osobine:<br />klijavost i vigor semena, enzimska aktivnost, nicanje u polju, nakupljanje suve materije (po<br />biljnim organima i ukupno po biljci), visina stabla, prečnik glave, prinos semena, masa 1000<br />semena, sadržaj ulja i prinos ulja. Statistička obrada podataka izvr&scaron;ena je primenom analize<br />varijanse trofaktorijalnog ogleda, prema modelu podeljenih parcela. Iz tabele analize<br />varijanse je prikazana verovatnoća značajnosti razlika po F-testu, a na osnovu uče&scaron;ća u<br />sumi kvadrata tretmana određen je procentualni udeo svakog faktora u ukupnoj<br />varijabilnosti. Takođe su izračunate i LSD vrednosti za poređenje razlika između tretmana<br />posmatranog faktora, na pragovima značajnosti od 1 i 5%. Utvrđena je i korelaciona<br />zavisnost posmatranih osobina. Rezultati analize varijanse pokazali su visoko značajno<br />uče&scaron;će glavnih faktora (godine, lokaliteta, frakcije semena, tipa ponika), kao i njihovih<br />međusobnih interakcija za većinu ispitivanih osobina. Na vrednosti ispitivanih osobina<br />najveći uticaj imala je godina istraživanja, a zatim lokalitet. Frakcija semena je imala visoko<br />značajan uticaj na klijavost semena, nicanje u polju, nakupljanje suve materije, prinos<br />semena i prinos ulja. Tip ponika je imao visoko značajan uticaj na enzimsku aktivnost</p> / <p>Five sunflower hybrids (Sremac, Oliva, Cepko, NS-H-111, and Sumo 2 OR) were grown in<br />2010 and 2011, on experimental fields of the Institute of Field and Vegetable Crops Novi<br />Sad - Rimski &Scaron;ančevi, and experimental fields of the Agricultural Service Zrenjanin.<br />Laboratory tests were conducted at Laboratory for Seed Testing of the Institute of Field<br />and Vegetable Crops Novi Sad, and Biochemical Laboratory of the Faculty of Agriculture,<br />University of Novi Sad. The aim of this research was to determine whether seed material<br />from the same locality and the same field lot changes quality during seed processing, i.e.<br />dividing seed lot into fractions, and additionally whether this type of seed processing<br />affects seed yield, seed yield components, oil yield, and oil content of the selected<br />sunflower hybrids. The aim was also to determine if missing primary root in sunflower<br />seedlings results in statistically significant decrease of seed and oil yield, and establish how<br />it influences sunflower yield components. The following traits were examined: seed<br />germination and vigour, enzymatic activity, field emergence, dry matter accumulation (in<br />plant organs and in the whole plant), stem height, head diameter, seed yield, 1000 seed<br />mass, oil content and oil yield. Statistical analysis of data was performed by analysis of<br />variance of the trifactorial trial using the split-plot design model. Table of analysis of<br />variance shows the probability of significance of differences by F-test, and based on the<br />participation in the treatment sum of squares, percentage ratio of each factor was<br />calculated in the total variability. LSD values at 1 and 5% were computed to compare<br />differences between treatments of the observed factor. Correlation dependence between<br />the observed traits was determined. Results of the analysis of variance showed a highly<br />significant participation of the main factors (year, locality, seed fraction, type of seedling),<br />and their mutual interactions for the majority of the examined traits. Year and locality had<br />the highest effect on the value of the examined traits. Seed fraction had highly significant<br />effect on seed germination, emergence, dry matter accumulation, seed yield, and oil yield.<br />Type of seedling had a highly significant effect on the enzymatic activity, seed yield, oil<br />content, and oil yield.</p>
