Resumo: Occurrence of sterile spikelets in wheat (Triticum aestivum L.) was determined during 1979 and 1980 at the Experimental Station of Lorena, SP, on holm soils. Application of micronutrients B, Fe, Mo, Mn, Cu and Zn as silicated oxydes (fritted trace elements - FTE) caused lower spikelet sterility and substantially greater yield in late maturity cultivars than in early cultivars. The occurrence of sterile spikelets was correlated with low relative humidity during the cultivar flowering stage. IAC-13 (Lorena) showed the best performance for grain yield.

A aplicação dos micronutrientes B, Fe, Mo, Mn, Cu e Zn em forma de óxidos silicatados (FTE) diminuiu o índice de chochamento e trouxe melhores resultados para as cultivares tardias do que para as precoces. A ocorrência de chochamento teve estreita relação com o grau de umidade relativa do ar no período da floração. O melhor desempenho em produção de grãos verificou-se na cultivar IAC-13 (Lorena).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFelício, João CarlosLeite, Norberto2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16308Pesquisa Agropecuaria Brasileira; v.17, n.10, out. 1982; 1417-1421Pesquisa Agropecuária Brasileira; v.17, n.10, out. 1982; 1417-14211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16308/10510info:eu-repo/semantics/openAccess2014-04-15T19:48:10Zoai:ojs.seer.sct.embrapa.br:article/16308Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
