Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chemical interactions. The level of phytotoxicity of allelochemicals is influenced by abiotic and biotic soil factors. Adopting suitable management strategies in crop rotation can reduce or eliminate allelochemicals phytotoxicity. Rice yields can be improved by growing rice in rotation with other crop species. Allelochemicals of rice can be used for control of weeds in this crop as well as other crops that are grown in rotation with rice. This review highlights that present knowledge of allelopathy in upland rice is inadequate and fragmentary, and therefore, more controlled and field studies are needed to understand and to reduce the detrimental effects of allelopathy in the upland rice production. |

ABSTRACT: The aim of this study was to evaluate the influence of pod wall permeability on the physiological quality of soybean seed. The cultivars studied were Sant'Ana, FT-2, FT-10, Bossier, Davis and the breeding line F 84-7-30, with a black seed coat. Pods were collected from plants at the R4, R5, R6, R7 and R8 development stages, which composed the treatments in regard to time of harvest. The parameters of permeability and the lignin content of the pods and the seeds within the pods were evaluated. The seeds were collected just after full maturity (R8), and the following tests were performed: germination, electrical conductivity, and tetrazolium, which determined seed viability and vigor. A randomized complete block design in a split-plot in time arrangement was used, with four replications per treatment. The soybean genotypes (six) composed the plots, and the split-plots consisted of the development stages (R4, R5, R6, R7 and R8). In seed evaluation, the same design was used, reducing the number of treatments to three in the split-plots (R6, R7 and R8). Pod permeability varied with the genotype and stage of development; this affected seed vigor, but not the viability of newly-harvested seeds. The pod lignin content did not show any influence on pod permeability. RESUMO: O objetivo do trabalho foi avaliar a influência da permeabilidade da parede da vagem na qualidade fisiológica das sementes de soja. As cultivares utilizadas foram Sant'Ana, FT-2, FT-10, Bossier, Davis e a linhagem F 84-7-30 com tegumento na cor preto. Coletaram-se vagens nos estádios de desenvolvimento R4, R5, R6, R7 e R8, sendo que os mesmos compuseram os tratamentos quanto à época de coleta. Avaliaram-se a permeabilidade e o conteúdo de lignina das vagens e das sementes no interior das mesmas. As sementes para os estudos foram obtidas logo após a maturidade plena (R8), sendo avaliadas a germinação, a condutividade elétrica e a viabilidade e o vigor pelo teste de tetrazólio. O delineamento experimental na avaliação das vagens foi em blocos ao acaso com parcelas subdivididas, sendo nas parcelas genótipos de soja (seis) e nas subparcelas estádios de desenvolvimento (R4, R5, R6, R7 e R8) com quatro blocos. Na avaliação das sementes utilizou-se o mesmo delineamento reduzindo o número de tratamentos para 3 nas subparcelas (R6, R7 e R8). A permeabilidade da vagem variou com o genótipo e com o estádio de desenvolvimento, e influenciou o vigor das sementes, entretanto, sem afetar a viabilidade das sementes recém-colhidas. O conteúdo de lignina nas vagens não teve influência sobre a permeabilidade das mesmas.
