Upland Rice And Allelopathy, N. K. Fageria, V. C. Baligar Jan 2003

Upland Rice And Allelopathy, N. K. Fageria, V. C. Baligar

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

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 …

Effects Of Submergence And Hypoxia On The Growth And Anatomy Of Rice (Oryza Sativa L.) Seedlings, Denise M. D'Abundo

LSU Doctoral Dissertations

Aerenchyma - a specialized tissue with abundant, interconnected gas spaces - facilitates oxygen transport from shoots to roots in many emergent wetland plants. The importance of oxygen transport to root elongation and aerenchyma development in rice (Oryza sativa L.) seedlings was demonstrated in this investigation. Germinated seeds of Lemont (a commercial cultivar) and red rice (an agricultural weed) were positioned at 4.5, 2.5, or 1.0 cm below the surface of aerated or hypoxic water to control the duration of leaf submergence and the availability of oxygen. Primary root and leaf lengths were measured daily. Aerenchyma was compared among emergent and …

Resistant Rice Starch Development, Siow Ying Tan Jan 2003

Resistant Rice Starch Development, Siow Ying Tan

LSU Master's Theses

This study showed that enzyme treatments were effective in producing resistant starch from rice flour and starch. Rice starch produced higher resistant starch yields than rice flour. The lower resistant starch yields in rice flour could be attributed to the presence of lipids and proteins which were competitively binding to amylose, resulting in decreased recrystallization of amylose. The gelatinization type and incubation periods were not as influential as enzyme treatments in the resistant starch formation. The rapid visco amylograph (RVA) analysis indicated that the gelatinized samples have minimal pasting characteristics since they had been gelatinized prior to enzyme treatments. Pasting …
