Rice Allelopathy and Momilactone
Rice has been extensively studied with respect to its allelopathy as part of a strategy for sustainable weed management options. All available information indicates that rice plants possibly release unknown allelochemicals into the neighbouring environments. A large number of compounds, such as phenolic acids, fatty acids, indoles and terpenes, were identified in rice root exudates and decompos...
متن کاملUpland Rice and Allelopathy
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 chem...
متن کاملImproving drought tolerance in rainfed lowland rice: An example from Thailand
A large portion of the world’s poor farm in rainfed systems where the water supply is unpredictable and droughts are common. In Thailand there are approximately 6.2 million ha of rain fed lowland rice, which account for 67% of the country’s total rice-growing area. This rice system is often characterised by too much and too little water in the same season. Farmers’ estimates of their annual los...
متن کاملRice—A Step Toward Use of Allelopathy
house and field experiments. Research to accomplish the above goals cannot be carried out in one laboratory, Rice (Oryza sativa L.) allelopathy has been on the research agenda and needs active collaboration among a wide range of for a decade. Now it is important to step back and look at its progress to enable priority setting for future research. This paper aims to do scientists, including biol...
متن کاملInvestigating crop processing using phytolith analysis: the example of rice and millets
The application of crop processing models to macro-botanical assemblages has traditionally been used to interpret past husbandry practices and organisation of labour involved in crop-processing. Phytoliths offer an alternative method of analysis because they are durable in most environments, regardless of whether plant parts are charred, and the identification of plant types and plant parts all...
