O presente estudo teve como objetivo avaliar o potencial de bactérias, na promoção de crescimento, produção de compostos de defesa e no biocontrole do mofo branco em folhas destacadas de duas cultivares de soja. Os ensaios foram realizados com as bactérias antagonistas FIT09 (Bacillus cereus) e FIT62 (B. thuringensis), do fungo Sclerotinia sclerotiorum e com as cultivares de soja M6210 IPRO e Brasmax Garra IPRO. Nos ensaios in vivo foram avaliados a capacidade das bactérias na promoção do crescimento de plantas de soja e na constituição dos compostos secundários produzidos pelas plantas oriundas de sementes microbiolizadas com suspensões bacterianas. Além disso, os ensaios de biocontrole do mofo branco, foram realizados com folhas destacadas em estádio V3, as quais foram pulverizadas com as suspensões das bactérias FIT09 e FIT62. As bactérias FIT09 e FIT62 apresentaram compatibilidade com B. japonicum e no ensaio de biocontrole com folhas destacadas, verificou-se que a FIT 09 reduziu o diâmetro das lesões necróticas causadas por S. sclerotiorum em ambas cultivares de soja avaliadas em teste de folhas destacadas. No ensaio de promoção de crescimento, as bactérias aumentaram o poder germinativo na cultivar M6210 IPRO. Para a avaliação da análise fitoquímica, as bactérias auxiliaram positivamente na produção dos compostos relacionados ao sistema de defesa. Palavras-chave: Metabólitos Secundários. Fitoquímica.

The tests were performed with the antagonist bacteria FIT09 (Bacillus cereus) and FIT62 (B. thuringensis), with the fungus Sclerotinia sclerotiorum and with the soybean cultivars M6210 IPRO and Brasmax Garra IPRO. In vivo tests evaluated the capacity of bacteria to promote the growth of soybean plants and the constitution of secondary compounds produced by plants from microbiolized seeds with bacterial suspensions. In addition,  white mold biocontrol bioassays were carried out with detached leaves in stage V3 and they were sprayed with suspensions of the bacteria FIT09 and FIT62.The bacteria FIT09 and FIT62 were compatible with B. japonicum and in the biocontrol assay with detached leaves, it was found that FIT09 promoted superior control of 70% against the disease in both cultivars, however the disease did not manifest in the assay in plants. In the growth promotion test, the bacteria increased the germinative power in cultivar M6210 IPRO, for the assessment of fresh and dry mass there were no differences and for phytochemical analysis, the bacteria positively helped in the production of compounds related to the defense system.   Keywords: Secondary Metabolites.

Experimental objectives were to assess metribuzin tolerance of predominately privately developed soybean cultivars and to evaluate a greenhouse screening procedure. In field results in 1982, ‘Vinton 81’, ‘Northrup King 1884’ and ‘L77-1863’ soybean cultivars were extremely sensitive to metribuzin at 0.56 kg/ha, averaging 34% injury. The other 45 cultivars showed no significant injury at the 0.56 kg/ha rate, from 9 to 46% injury at 1.4 kg/ha, and 18 to 72% injury at 2.2 kg/ha. In greenhouse hydroponic studies, these same three soybean cultivars were killed, while the other 45 cultivars were injured from 15 to 82%. A good agreement of greenhouse and field data was determined, with a correlation coefficient of r = 0.82.

Species Translocation

The uptake, translocation, and metabolism of the ethyl ester of chlorimuron in three soybean cultivars and two morningglory species was investigated. Soybean used included the normal cultivars ‘Vance’ and ‘Essex,’ and the sulfonylurea-resistant cultivar ‘W-20.’ Entireleaf morningglory and pitted morningglory, both moderately tolerant to chlorimuron, were used. Twenty-day-old seedlings of all plant species were exposed to root-applied14C-labeled chlorimuron for 6, 24, and 72 h. After 24 and 72 h, chlorimuron uptake was lowest in W-20 soybean and the two morningglory species. Translocation of root-absorbed chlorimuron to shoots and leaves of all species was limited and it did not differ among species. The moderate tolerance of pitted and entireleaf morningglories to chlorimuron may be due to reduced herbicide uptake. The response of Essex and Vance soybean to chlorimuron was related to herbicide metabolism. At 6 h after treatment with radiolabeled chlorimuron, Essex soybean metabolized the herbicide more rapidly than either W-20 or Vance soybean. At 24 h and 72 h, Essex and Vance soybean metabolized chlorimuron to the same extent. W-20 was not very efficient in metabolizing chlorimuron at any time after treatment and its resistance to chlorimuron is due to an altered target site.

Soybean (Glycine max (L.) Merr.) cultivars were tested for yield at various populations in hillplots that had plants compactly clumped and in comparative hill and row plots. Results indicated that thinning to a uniform stand should be worthwhile in cases where population varies and that selection in hills for material to be grown in rows could be from 43 to 95% as effective as direct selection in row plots.Key words: Glycine max, soybean cultivars, plant density, yield, hill plots, selection

Ten commercial soybean [Glycine max (L.) Merr.] cultivars were evaluated for reaction to over-the-top applications of two rates of 3′,4′-dichloropropionanilide (propanil) at the growth stage when three nodes on the main stem had completely unrolled leaves. Propanil, a herbicide commonly applied to rice [Oryza sativa L.] for control of grass weeds, was applied at 0.56 and 3.36 kg/ha; the higher rate is commonly used for control of weeds in rice. ‘Davis’, ‘Hood’, and ‘York’ soybean cultivars were damaged more by propanil than ‘Hill’, ‘Lee’, ‘Lee 68’, ‘Pickett’, ‘Semmes’, ‘Bragg’, or ‘Dare’ when damage was measured by reductions in seed yield and stand and by leaf injury.

Soybean cultivars were grown in a hydroponic culture to evaluate tolerance to dimethenamid and metolachlor. Root length was reduced in 7 of the 32 cultivars with 50 ppb dimethenamid. ‘Asgrow 5403’ and ‘Bryan’ root lengths were reduced more than 20%. ‘Asgrow 6297’ was the only cultivar with greater than 12% root length reductions with 83 ppb metolachlor. The longest lateral root of all cultivars was shortened with dimethenamid. ‘NK-1460’ and Bryan expressed the most lateral root length reduction, at 73 and 62%, respectively. Asgrow 6297 was tolerant to dimethenamid, but lateral roots were reduced 16%. Metolachlor reduced the lateral root lengths of 12 cultivars, with Asgrow 5403, ‘Coker 6955,’ and Bryan reduced more than 20%. Bryan was the most sensitive cultivar to both herbicides, while ‘Brim’ was the most tolerant of cultivars evaluated.

Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves. The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds. Meanwhile, according to the different expression levels of RSTK, ISCP, and H+-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H+-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

O presente trabalho foi realizado com o objetivo de avaliar os teores de óleo e proteína dos grãos em cultivares de soja em função do retardamento da colheita e verificar a influência da época de semeadura sob condições de baixa latitude. No ano agrícola de 2015/16, foram realizados dois ensaios de competição de cultivares de soja em Palmas-TO, sendo o primeiro instalado em 17 de dezembro de 2015 e o segundo em 04 de janeiro de 2016. O delineamento experimental utilizado em cada época de semeadura foi de blocos casualizados com setenta tratamentos e cinco repetições. Os tratamentos foram dispostos em um esquema de parcelas subdivididas, representados por dez genótipos de soja (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR), nas parcelas, e por sete estádios de colheita dos grãos (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias), nas subparcelas. Houve efeito das épocas de plantio e dos estádios de colheita nos teores de óleo e proteína dos grãos. As cultivares apresentaram comportamentos diferenciados nas duas épocas de semeaduras, a cultivar M9144 RR obteve um crescente aumento nos teores de proteína na segunda época com retardamento da colheita dos grãos. A partir do estádio R8 de desenvolvimento, o teor de óleo nos grãos de três cultivares foi maior na primeira época de semeadura. Na segunda época, quatro cultivares mostram aumento no teor de óleo a partir de R8.Palavras-chave: Glycine Max L.; retardamento; composição química dos grãos. EPOCH AND AFTER DELAYED OF SOYBEAN HARVEST VISUALIZING OIL AND PROTEIN PRODUCTION  ABSTRACT: The present work was carried out with the objective of evaluate the oil and protein contents of the grains in soybean cultivars as a function of the harvest delay and to verify the influence of the sowing season under conditions in low latitude. In the agricultural year 2015/16, two competition trials of soybean cultivars were carried out in Palmas-TO, the first one being installed on December 17, 2015 and the second on January 4, 2016. The experimental design used at each time were randomized blocks with seventy treatments and five replications. The treatments were arranged in a scheme of subdivided plots, represented by ten soybean genotypes (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR, on the plots, and seven stages of grain harvest (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias) in the subplots. There was an effect of planting times and harvest stages on the oil and protein contents of the grains. The cultivars presented different behaviors in the two sowing seasons; the cultivar M9144 RR obtained an increasing increase in the protein content in the second season with grain harvest delay. From the R8 development stage, the oil content in the grains of three cultivars was higher in the first sowing season. In the second season, four cultivars show an increase in oil content from R8.Keywords: Glycine max L.; retardation; chemical composition of grains.
